Answer:

x=4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

0.75x+3=6(x−3)

0.75x+3=(6)(x)+(6)(−3)(Distribute)

0.75x+3=6x+−18

0.75x+3=6x−18

Step 2: Subtract 6x from both sides.

0.75x+3−6x=6x−18−6x

−5.25x+3=−18

Step 3: Subtract 3 from both sides.

−5.25x+3−3=−18−3

−5.25x=−21

Step 4: Divide both sides by -5.25.

−5.25x/-5.25    =    -21/-5.25

Answer: x=4

The value of x from the given equation is 4.

The given equation is 0.75x + 3 = 6 (x - 3).

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation can be solve for x as follows:

0.75x + 3 = 6x - 18

⇒ 6x-0.75x = 3+18

⇒ 5.25x=21

⇒ x=21/5.25

⇒ x=4

Therefore, the value of x from the given equation is 4.

Answer:

The true statements are the 1st, 2nd, and 4th statement.

Answer:

Angle 1: 127

Angle 2: 153

Step-by-step explanation:

First, let's find angle 1 by finding the angle that's supplementary to it.

To solve for it, we can set up an equation where the unknown angle and the other angles in the triangle it's in add up to 180:

x+95+32=180

x=53

Since angle 1 is supplementary to 53, that means that angle 1 is equal to 180-53 = 127.

Then, to find angle 2, we can find the angle that's supplementary to it.

To solve for that, we can set up an equation where that unknown angle and the other angles in the triangle it's in add up to 180:

26+127+x = 180

x = 27

Since angle 2 is supplementary to 27, that means that angle 2 is equal to 180-27 = 153.

Explanation:

In the LS column, you'll have these steps

3x - 1

3*4 - 1

12 - 1

11

Effectively, we replaced x with 4 and then simplified using PEMDAS.

And in the RS column, you'll have these steps

x + 7

4 + 7

11

We get the same thing at the bottom of each column. This shows that we end up with 11 = 11 after simplifying both sides. Therefore, we've confirmed that x = 4 is the solution to 3x - 1 = x + 7

Answer:

Step-by-step explanation:

Step-by-step explanation:

We are given a regression model: test score = 800 - 8(student-teacher ratio)

If the student-teacher ratio drops by 2, then the new ratio is (old ratio - 2).

So, the new predicted test score is:

test score = 800 - 8(new ratio)

          = 800 - 8(old ratio + (-2))

          = 800 - 8(old ratio) - 8(-2)

          = 800 - 8(old ratio) + 16

Therefore, the predicted effect on the test score is an increase of 16 points.

So, the answer is (d) the test score will increase by 16 points.

1In unit 10 circles homework 9 standard form of a circle in all things' algebra, the center is (0,-2) and radius is 8 units.

The equation of the circle is the equation which is used to represent the circle in the algebraic equation form, with the value of center point in the coordinate plane and measure of radius.

The standard form of the equation of the circle can be given as,

\((x-h)^2+(y-k)^2=r^2\)

Here (h,k) is the center of the circle and (r) is the radius of the circle.

For the first problem,

\(x^2+(y+2)^2=64\)

Rewrite the equation to make it the equation of circle as,

\((x-0)^2+(y-(-2))^2=8^2\)

Compare it with equation of circle, we get center at (0,-2) and radius of 8 units. Similarly, the center and radius for each of the equation can be found out.

The classification of each pair of angles is given below.

What is an angle?

When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together.

The Latin word "angulus," which means "corner," is the source of the English term "angle." The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle.

Corresponding angle = figure 3 and figure 5

Alternate interior angle = figure 4

Alternate exterior angle = figure 1

None of these = figure 2

The number of intersections of the graphs of the given equations is 0.

To determine the number of intersections of the graphs of the equations:

1. One-halfx + 5y = 6

2. 3x - 30y = 36

We can convert the equations to slope-intercept form (y = mx + b) by isolating y:

1. \(\frac12\\\)x + 5y = 6

  5y = -\(\frac12\\\)x + 6

  y = (-1/10)x + 6/5

2. 3x - 30y = 36

  -30y = -3x + 36

  y = (1/10)x - 36/30

  y = (1/10)x - 6/5

Now, we can observe that both equations have the same slope, which is 1/10, but they have different y-intercepts (6/5 and -6/5).

Since the slopes are the same but the y-intercepts are different, the two lines are parallel.

Parallel lines do not intersect,

so the graphs of these equations have no intersection points.

Linearity is a trait or feature of a mathematical item or system that complies with the superposition and scaling concepts. Linear systems, equations, and functions are frequently referred to as linear in mathematics and physics.

a) Here are the steps to show that T is a linear map which is surjective and injective.

i) Linearity of TT to prove linearity, we want to show that

T(αA+βB) = αT(A) + βT(B) for all

α,β ∈ R and all

A,B ∈ Matn,m(R).αT(A) + βT(B)

= αA' + βB', where A' = AT and B' = BT.

Then(αA+βB)' = αA' + βB'. Thus, T is a linear map

ii) Surjectivity of TT To prove surjectivity, we need to show that for every B in Matm,n(R), there exists some A in Matn,m(R) such that T(A) = B. Take any B in Matm,n(R).

b) Here are the steps to show that (AB)t = BtAt.We want to prove that the matrix on the left-hand side is equal to the matrix on the right-hand side. That is, we want to show that the entries on both sides are equal.

Let (AB)t = C. That means that

ci,j = aji. bi,k for all 1 ≤ i ≤ m and 1 ≤ k ≤ p.

Also, let BtAt = D. That means that

di,j = ∑aikbkj for all 1 ≤ i ≤ m and 1 ≤ j ≤ p.

Let's calculate the i,j-th entry of C and D separately. For C, we have that ci,j = aji.bi,k.

c) Here are the steps to show that (At)t = A. Note that A is an m x n matrix. Let's denote the entry in the i-th row and j-th column of At by aij'. Similarly, let's denote the entry in the i-th row and j-th column of A by aij. By the definition of the transpose, we have that aij' = aji.

d) Here are the steps to show that if A is invertible, then AtA is invertible and

(At)−1 = (A−1)t.

Since A is invertible, we know that A-1 exists. We want to show that AtA is invertible and that

(At)-1 = (A-1)t.

Let's calculate (At)(A-1)t. We have that

(At)(A-1)t = (A-1)(At)t = (A-1)A = I,n where I,n is the n x n identity matrix. Therefore, (At) is invertible and (At)-1 = (A-1)t.

The length longer diagonal is 174 cm.

In a rhombus, the diagonals bisect each other as well as the the vertex angles and adjacent angles are supplementary

So assuming that the 70 degree angle is opposite the 122 cm diagonal, we have

(1/2 length of the shorter diagonal) / sin (35)  = (1/2 length of the longer diagonal) / sin(55)

Multiply both sides by 2

( length of the shorter diagonal) / sin (35)  = ( length of the longer diagonal) / sin(55)

Multiply both sides by sin(55).

Length of the longer diagonal = sin (55) (122 cm) / sin (35) = 174 cm

Therefore, the length of the longer diagonal is 174 cm.

A density graph of temperatures shows the frequency of different temperature values.

A density graph for all of the possible temperatures from 60 degrees to 260 degrees can be used to find the probability density function (PDF) of a continuous random variable that represents temperature within that range. The PDF describes the relative likelihood of observing different temperature values within the range, taking into account the continuous nature of temperature.

The density graph shows the distribution of temperature values, with the height of the graph at a given temperature indicating the relative probability of observing that temperature. The area under the density graph within a given range of temperatures represents the probability of observing a temperature within that range.

Therefore, a density graph can be used to find the probabilities of observing different temperatures within the given range and to analyze the distribution of temperatures within that range.

Total area of board = 36x² + 324 + 216x

Step-by-step explanation:

Given:

Side of square = x + 3

Total number of square = 6 x 6 = 36

Area of each square = Side x Side

Area of each square = (x + 3)²

Area of each square = x² + 9 + 6x

Total area of board = 36[Area of each square]

Total area of board = 36[x² + 9 + 6x]
