Answer:

r = -14

Step-by-step explanation:

22 = r/7 + 24 <-- try and isolate r

22-24 = r/7

-2 = r/7

-2(7) = r

r = -14

Answer:

-14

Step-by-step explanation:

subtract 24 on both sides

-2=r/7

-14=r

Answer: 420 legislators

Step-by-step explanation:

For this problem, we would have to multiply.

If Alabama has 140 legislators for 4 million people, we know the unit rate is:

[tex]140[/tex] legislators for [tex]4[/tex] million people.

So, we have to multiply 140 by 3 because 12 is 3 times the amount of 4, and the other state has 12 million people.

140 x 3 = 420

The answer to the question would be 420.

Answer:

420

Step-by-step explanation:

I set this up as a proportion of 140/4,000,000=x/12,000,000. Then you can cross multiply, getting 1,680,000,000=4,000,000x. Divide both sides by 4,000,000 and you get x=420. Please mark brainliest if this helped!

Answer:  m = 2/5

Step-by-step explanation:

The formula for the slope is m = rise over run = y^2 - y^1 / x^2 - x^2

which makes it 4-2 over 3-(-2) which equals 2/5

Youre answer is 2/5

Answer:

The slope of the line that contains the points (-2, 2) and (3, 4) is 2/5.

Step-by-step explanation:

The slope of a line is denoted by m and is calculated using the formula:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Here

[tex](x_1,y_1)[/tex] are the coordinates of the first point on line and

[tex](x_2,y_2)[/tex] are the coordinates of the second point on line

Given two points are:

(x1,y1) = (-2, 2)

(x2,y2) =(3, 4)

Putting the values in the formula

[tex]m = \frac{4-2}{3-(-2)}\\m = \frac{2}{3+2}\\m=\frac{2}{5}[/tex]

Hence,

The slope of the line that contains the points (-2, 2) and (3, 4) is 2/5.

is 16 or 30 lol

Step-by-step explanation:

....................

You need to follow the order of operations, so you would solve what is in the parentheses first. (I'm assuming that is the variable x in 2x and not a multiplication symbol. If it is, then just multiply 5 by 3 to get 15, and then multiply that by 2 to get 30) This will give you 15. Then you multiply 2x by 15 to get 30x.

Answer:

x^2-2x+3

Step-by-step explanation:

Answer:

x ≈ 1.32, x ≈ - 5.32

Step-by-step explanation:

Given

x² + 4x - 7 = 0 ( add 7 to both sides )

x² + 4x = 7

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(2)x + 4 = 7 + 4

(x + 2)² = 11 ( take the square root of both sides )

x + 2 = ± [tex]\sqrt11}[/tex] ( subtract 2 from both sides )

x = - 2 ± [tex]\sqrt{11}[/tex]

Thus

x = - 2 - [tex]\sqrt{11}[/tex] ≈ - 5.32 ( to 2 dec. places )

x = - 2 + [tex]\sqrt{11}[/tex] ≈ 1.32 ( to 2 dec. places )

the answer is yes

Step-by-step explanation:

Answer:

B.) 55 degrees

Step-by-step explanation:

Angle 4 is complementary to angle 5.

The two triangles with these two angles inside are congruent.

So angle 5 is congruent to the given angle of 35 degrees.

Thus,

90 = 35 - x

X = 90 - 35

X = 55

Answer:

3p + 89 < 765

Correct answer: D.

Step-by-step explanation:

Austin, his dad, and brother make a group of three people of varying weights. Assume their average weight is p and their total weight 3p.

The cooler and other supplies weigh 89 pounds in total.

The weight of the supplies and the three people in the canoe should not be equal or exceed the maximum allowable weight of the canoe of 765 pounds.

This leads to inequality:

3p + 89 < 765

Correct answer: D.

The value of x must be 3, for quadrilateral WXYZ to be a parallelogram

The given parameters are:

[tex]\mathbf{CY = 3x + 2}[/tex]

[tex]\mathbf{WC = 2x + 5}[/tex]

From the question, we understand that:

Segments ZC and CX are congruent

This means that:

Segments WC and CY are congruent

So, we have:

[tex]\mathbf{WC = CY}[/tex]

This gives

[tex]\mathbf{3x +2 = 2x + 5}[/tex]

Collect like terms

[tex]\mathbf{3x + 2x =-2 + 5}[/tex]

[tex]\mathbf{x =3}[/tex]

Hence, the value of x must be 3, for quadrilateral WXYZ to be a parallelogram

Answer:

The measure of angle Q'R'S' is 35°

Step-by-step explanation:

The given parameters are;

The measure of angle QRS = 35°

The transformation applied to triangle QRS = 90° clockwise rotation

For a 90° clockwise rotation, we have;

Coordinate of the preimage (x, y), coordinate of the image after rotation (y, -x)

Given that the distance, d, between points is given by √((x₂ - x₁)² + (y₂ - y₁)²), we have that the distance between points of the image will be given as follows;

d' =√((y₂ - y₁)² + ((-x₂) - (-x₁))²) = √((y₂ - y₁)² + (x₁ - x₂)²)

Whereby we have √((y₂ - y₁)² + (x₁ - x₂)²) = √((x₂ - x₁)² + (y₂ - y₁)²)

Therefore, d = d' and the length of the sides and measures of the angles in ∠QRS and ∠Q'R'S' will be equal and ∠Q'R'S' = ∠QRS = 35°.

Answer:

y-7= -1/5x

Step-by-step explanation:

general formula (y-y1)= m(x-x1)

m is the slope and in this case m=-1/5

(x1, y1) is a point on thhe line in this case is (0, 7) because f(x)=y

substitute your given in the equation

(y-7) = -1/5(x-0)

y-7= -1/5x
