Step-by-step explanation:

System of the equations have been given as,

\(y=x+1\) --------(1)

\(y=-\frac{1}{2}x+4\) -------(2)

Substitute the value of y from equation (1) to equation (2),

\(x+1=-\frac{1}{2}x+4\)

\(x+1=-\frac{1}{2}x+4\)

\(x+\frac{1}{2}x=4-1\)

Answer: g(x)=9^x-7

Step-by-step explanation:

The equation of the tangent line to the hyperbola y = f(x) at the point (4, 1.750) is y = 7x - 26.250.

Where, the slope, m = 7, and the y-intercept, b = -26.250.

Given that f(x) =  and f'(4) = 7, we can find the equation of the tangent line to the hyperbola y = f(x) at the point (4, 1.750).

The equation of a tangent line can be expressed in the point-slope form, which is given by:

y - y1 = m(x - x1),

where (x1, y1) is the point of tangency and m is the slope of the tangent line.

In this case, (x1, y1) = (4, 1.750), and

we know that the slope of the tangent line, m, is equal to f'(4), which is 7.

Using these values, we can write the equation of the tangent line as:

y - 1.750 = 7(x - 4).

To simplify further, we expand the equation:

y - 1.750 = 7x - 28.

Next, we isolate y:

y = 7x - 28 + 1.750,

∴The required equation is: y = 7x - 26.250.

In order to determine whether a critical point of a loss function is a global minimum, it is necessary to consider the second derivative of the function.

If the second derivative is positive at the critical point, then we can say with certainty that the critical point is a local minimum. However, this does not necessarily mean that it is a function function. This is because there may be other local minima at points which the second derivative is negative, and in this case, the critical point must be compared to these points to determine if it is indeed the global minimum.

In order to assess whether a local minimum is a global minimum, we must first identify any other local minima. This can be done by locating the points at which the first derivative of the function is equal to zero and then evaluating the second derivative of the function at these points. If the second derivative is negative at any of the points, then we have identified a local minimum. Then, we can compare the value of the loss function at the points function as local minima to the value of the loss function at the critical point. If the value of the loss function at the critical point is lower than the value of the loss function at the other local minima, then the critical point is the global minimum. If the values are equal, then the critical point is a global minimum if and only if it is the only local minimum.Overall, identifying whether a critical point of a loss function is a global minimum requires both sufficiency and necessity. It is necessary to evaluate the second derivative of the function at the critical point in order to determine whether it is a local minimum, and it is also necessary to identify any other local minima and compare the value of the loss function at the critical point to the value of the function at the other local minima in order to determine whether the critical point is the global minimum.

Answer:

P'(-8, -2), Q'(-4, -4), R'(0, -2) and  S'(-4, 0)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.

Reflection is the flipping of a point about an axis.

Given the Rhombus PQRS with vertices P(-8, 6), Q(-4, 8), R(0, 6), and S(-4, 4), if the rhombus is reflected over the y = 2 line the new point is:

For P(-8, 6): The point P has a y coordinate 4 units above the y = 2 line. Hence if it is reflected over the line y = 2, the new point would have a y coordinate 4 units below the y = 2 line which is P'(-8, -2)

For Q(-4, 8): The point Q has a y coordinate 6 units above the y = 2 line. Hence if it is reflected over the line y = 2, the new point would have a y coordinate 6 units below the y = 2 line which is Q'(-4, -4)

For R(0, 6): The point R has a y coordinate 4 units above the y = 2 line. Hence if it is reflected over the line y = 2, the new point would have a y coordinate 4 units below the y = 2 line which is R'(0, -2)

For S(-4, 4): The point S has a y coordinate 2 units above the y = 2 line. Hence if it is reflected over the line y = 2, the new point would have a y coordinate 2 units below the y = 2 line which is S'(-4, 0)

Therefore the reflected rhombus is at P'(-8, -2), Q'(-4, -4), R'(0, -2) and  S'(-4, 0)

The right hand side ranges for the five constraints are:

Constraint 1: 0 ≤ RHS ≤ (30 - 6x1 - 4x2) / 4

Constraint 2: 0 ≤ RHS ≤ (110 - 4x1 - 5x2) / 2

Constraint 3: 0 ≤ RHS ≤ 200

Constraint 4: 600 ≤ RHS ≤ ∞

Constraint 5: 0 ≤ RHS ≤ 1000

The right-hand-side (RHS) ranges indicate the allowable range of values for the constraints in a linear programming problem. To find the RHS ranges for this problem, we need to analyze each constraint and determine the range of values that the RHS can take without changing the optimal solution.

Let x1, x2, and x3 be the number of units of components 1, 2, and 3 produced, respectively.

Constraint 1: Shaper availability

The total time required on the shaper is:

6x1 + 4x2 + 4x3

This must be less than or equal to the shaper availability of 120 hours:

6x1 + 4x2 + 4x3 ≤ 120

Solving for x3, we get:

x3 ≤ (30 - 6x1 - 4x2) / 4

The RHS of this constraint can take any value less than or equal to the expression (30 - 6x1 - 4x2) / 4, without changing the optimal solution. Therefore, the RHS range for this constraint is:

0 ≤ RHS ≤ (30 - 6x1 - 4x2) / 4

Constraint 2: Grinder availability

The total time required on the grinder is:

4x1 + 5x2 + 2x3

This must be less than or equal to the grinder availability of 110 hours:

4x1 + 5x2 + 2x3 ≤ 110

Solving for x3, we get:

x3 ≤ (110 - 4x1 - 5x2) / 2

The RHS of this constraint can take any value less than or equal to the expression (110 - 4x1 - 5x2) / 2, without changing the optimal solution. Therefore, the RHS range for this constraint is:

0 ≤ RHS ≤ (110 - 4x1 - 5x2) / 2

Constraint 3: Component 3 limit

The number of units of component 3 produced must be less than or equal to 200:

x3 ≤ 200

The RHS of this constraint can take any value less than or equal to 200, without changing the optimal solution. Therefore, the RHS range for this constraint is:

0 ≤ RHS ≤ 200

Constraint 4: Component 1 demand

The number of units of component 1 produced must be at least 600:

x1 ≥ 600

The RHS of this constraint can take any value greater than or equal to 600, without changing the optimal solution. Therefore, the RHS range for this constraint is:

600 ≤ RHS ≤ ∞

Constraint 5: Component 2 demand

The number of units of component 2 produced must be less than or equal to 1000:

x2 ≤ 1000

The RHS of this constraint can take any value less than or equal to 1000, without changing the optimal solution. Therefore, the RHS range for this constraint is:

Answer:

x = 11

z = 86

Step-by-step explanation:

8x + 6 and 10x-16 are vertical angles

Vertical angles are pairs of angles that are opposite each other and have the same vertex, or point of intersection. They are formed when two lines intersect at a point, and are always congruent, or of equal measure.

To solve this equation, we need to isolate the variable x on one side of the equation. To do this, we can start by subtracting 6 from both sides of the equation:

8x + 6 - 6 = 10x - 16 - 6

8x = 10x - 22

Now we can subtract 8x from both sides of the equation:

8x - 8x = 10x - 22 - 8x

0 = 2x - 22

To solve for x, we can add 22 to both sides of the equation:

0 + 22 = 2x - 22 + 22

22 = 2x

Finally, we can divide both sides of the equation by 2 to find the value of x: 22 / 2 = 2x / 2

x = 11

Therefore, the solution to the equation is x = 11.

Now that we have x, z is a supplementary angle to 8x + 6 (or you could do 10x - 16)

Supplementary angles are pairs of angles that add up to 180 degrees. They are formed when two lines intersect at a point, and the angles formed at the intersection are supplementary.

First plug in x, 8x + 6 = 8(11) + 6 = 88 + 6 = 94

180 - 94 = z

z = 86

The equation that can be used to calculate the time in this scenario is:Time = Distance / Rate

In this case, the distance refers to the depth of Happy Valley, and the rate refers to the speed at which the valley floor is being lowered. By dividing the distance by the rate, you can determine the time that has been used in the lowering of the valley floor.

In the given scenario, we are trying to calculate the time it takes for the valley floor to lower in Happy Valley. We have two quantities: the distance (depth of Happy Valley) and the rate (speed at which the valley floor is being lowered).

To calculate the time, we can use the formula:

Time = Distance / Rate

This formula applies to situations where you have two known quantities and want to find the third. In this case, by dividing the distance (depth of Happy Valley) by the rate (speed at which the valley floor is being lowered), we can determine the time it has taken for the valley floor to lower.

By applying the same principle as the example of driving at a certain speed for a certain distance, we can calculate the time involved in the geological process of the valley floor lowering in Happy Valley.

Answer:

Step-by-step explanation:

To be parallel the slopes must be equal

4x-3y=15

3y=4x-15

y=(4x-15)/3

so m=4/3

Only line D. has a slope of 4/3

Answer:

D. y = (⁴/₃)x – 1

Step-by-step explanation:

To find the answer to this problem, we need to find the slope of 4x – 3y = 15 . Why? A line that is parallel to another line has the same slope as the other line.

The question gives the line in standard form, but all the options are in slope-intercept form. In addition, standard form is the only type of linear equation that does not explicitly give the slope. The slope is the change in the dependent variable, y, over the change in the independent variable, x. This means we need to solve the equation for y and so:

4x – 3y = 15  — original equation

4x – 3y – 4x = 15 – 4x  — subtracting 4x on each side to isolate 3y and reverse the addition of 4x

–3y = 15 – 4x  — simplifying; the 4x on the left cancels out

–3y ÷ –3 = (15 – 4x) ÷ –3  — dividing both sides by –3 to isolate y

–3y ÷ –3 = (15 ÷ –3) + (–4x ÷ –3)  — distributing the division by –3 on the right side to make it easier to understand

y = (⁴/₃)x – 5  — simplifying; this is our expression for y, and it gives us the slope

Now, which line has a slope of ⁴/₃? That would be Option D, y = (⁴/₃)x – 1, so that's our answer.

Of course, you could have just found two points on the graph and then used point-slope form to solve for the slope, but that takes more time…

I hope this makes it easier to understand the concept! Have a great day!
