By solving the system using elimination method 5x + 4y = 12 and 3x -3y = 18 we get x = 4 and y = -2.

What is Elimination Method?

To create an equation in one variable using the elimination approach, you can either add or subtract the equations. To eliminate a variable, add the equations when the coefficients of one variable are in opposition, and subtract the equations when the coefficients of one variable are in equality.

Now solving the both equation by using elimination method;

5x +4y = 12                                                     ----------------------------eq(1)

3x - 3y = 18                                                     ----------------------------eq(2)

Multiply equation (1) by 3 and equation (2) by 4,  we get;

15x + 12y = 36

12x - 12y = 72

Now, same equation will beb together;

15x + 12y + 12x - 12y = 36 + 72

15x + 12x = 36 + 72

27x = 108

x = 108/27

x = 4

Now, we calculate for the y ;

3x - 3y = 18

3 * 4 - 3y = 18

12 - 3y = 18

12 - 18 = 3y

3y = -6

y = -6/3

y = -2

(x, y) = (4, -2)

So, by solving the system using elimination method 5x + 4y = 12 and 3x -3y = 18 we get x = 4 and y = -2.

The statement that is true about the function is:

A function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given:

The minimum value of the curve = (1.9, -5.7),

The maximum value = (0, 2)

The point the function crosses the x-axis (the x-intercept) = (-0.7, 0), (0.76, 0), and (2.5, 0)

The point the function crosses the y-axis (the y-intercept) = (0, 2)

The given points can be plotted using MS Excel, from which we have:

F(x) is less than 0 over the interval from x = -∞, to x = -0.7, and the interval from x = 0.76 to x = 2.5.

Hence, the correct option is A.

Answer: The value of 5w - 2 is -12

Step-by-step explanation:

First, solve for w in the equation of -7w-7=7

Add 7 to both sides to isolate -7w

You then get: -7w=14

Divide both sides by -7 to isolate w

You then get: w=-2

Then substitute -2 for w into the equation 5w-2

You then get: 5(-2)-2

Simplify and you get the final answer of -10-2=-12

Answer: The answer to the equation 5w-2 is -12, since w is -2

Step-by-step explanation:

We are given this equation:

−7w-7=7

==> −7w-7=7 ( add 7 to both sides)

==> -7w = 14 ( divide both sides by -7)

==> w = -2

Now that we know the value for w, we can solve the former equation;

==> 5w-2

=> 5(-2) -2 (distributive property)

=> -10 -2

=> -12

The answer to the equation 5w-2 is -12, since w is -2

The set (A U B) n (A U C) is {2, 5, 7, 10}. A.

To find the set (A U B) n (A U C), we first need to calculate the union of sets A and B, and then calculate the union of that result with set C. Finally, we find the intersection of these two sets.

Set A U B:

The union of sets A and B, denoted as A U B, is the combination of all elements from both sets without any repetitions.

A contains the elements 2, 5, 7, and 10, while B contains the elements 1, 2, and 3.

A U B consists of the elements {1, 2, 3, 5, 7, 10}.

Set (A U B) U C:

Next, we calculate the union of the set (A U B) with set C, denoted as (A U B) U C. A U B contains the elements {1, 2, 3, 5, 7, 10} and C contains the elements {1, 2, 3, 4, 5}.

Taking the union of these two sets results in {1, 2, 3, 4, 5, 7, 10}.

Finding the intersection:

Finally, we find the intersection of (A U B) U C with A U C. A U C consists of the elements {2, 5, 7, 10}.

The intersection of these two sets is the combination of common elements.

The common elements are {2, 5, 7, 10}.

Answer:

T = (3,16)

Step-by-step explanation:

The midpoint formula is just another version of the pythagorean theorem, and it states that the midpoint between (x1,y1) and (x2,y2) is \(\left(\frac{x_1+x_2}{2}\right),\:\left(\frac{y_1+y_2}{2}\right)\)

Substituting what we know:

endpoint S is (3,2) and endpoint T is (x2,y2)

Midpoint Z is (3,9). We will apply the formula -- backwards.

\(\left(\frac{3+x_2}{2}\right)=3\), solving with algebra we get x2 = 3

So the x-coordinate of endpoint T is 3.

\(\left(\frac{2+y_2}{2}\right)=9\quad\), solving with algebra, we get y2 = 16.

So the y-coordinate of endpoint T is 16.

So the location of endpoint T is (3,16)

If there are b ounces of water in a bottle, b + 5 could represent the amount of water after you drink 5 bottles.

The algebraic expression for this problem is defined as follows:

Answer:

1.5 meters

Step-by-step explanation:

The formula for the area of a trapezoid is h * (a+b)/2, where a is the first base and b is the second base. Now, we can work backwards to determine the height of the trapezoid:

3.75=h*(1.7+3.3)/2

3.75=h*2.5

h=3.75/2.5=1.5

Hope this helps!

Answer:

Step-by-step explanation:

use the formula and rearrange for h.

1/2 x h x  (a + b) = A

1/2 x (1.7 + 3.3) x h = 3.75

2.5 x h = 3.75

h = 1.5

The information of ZY = 15 also gives the value of YX. ZY is the radius of the greater circle inside the big circle. So we have that:

The radius of the circle that has the center on X (the big one) is the sum of ZY and YX. This value is also equal to UX! Therefore:

If UX is 30 and the question says that WX is 10, we can find the following equation:

Obs: UV = VW (radius of the circle). Then we can find UW using the equation above (UW is the diameter of the circle with center V).

The diameter of a circle is two times the radius. Thus:

Then the radius of the circle V will be:

A personal example of a measurement I use routinely is converting weight from U.S. customary units to metric units. Let's convert pounds to kilograms.

To convert pounds to kilograms, we use the conversion factor of 1 pound = 0.453592 kilograms.

For example, if I have a weight of 150 pounds, I can calculate the equivalent weight in kilograms as follows:

150 pounds * 0.453592 kilograms/pound = 68.0388 kilograms

Therefore, 150 pounds is approximately equal to 68.0388 kilograms.

In this conversion, we multiply the weight in pounds by the conversion factor to obtain the weight in kilograms. By using the appropriate conversion factor, we can accurately convert weights from U.S. customary units to metric units.

It's important to note that conversion factors may vary slightly depending on the rounding used and the exact value of the conversion factor.
