Answer:

f^-1 (x) = -21x + 7 is your answer

Answer: slope=-1, y-intercept=(0,-4)

Step-by-step explanation:

Answer:

1

Step-by-step explanation:

first you have to find the slope of the original question

2x+2y=-8

2y= -8 -2x

y= -4-x

slope = -1

to find the perpendicular slope you flip it and multiply by -1

-1 -> -1 *-1 -> 1

Answer: not congruent

Step-by-step explanation:

To know if CD and EF are congruent, you need to use the distance formula to find CD and EF. If the distance is the same, then they are congruent.

Distance formula: [tex]d=\sqrt{(x_{2}-x_1)^2+(y_2-y_1)^2}[/tex]

CD

[tex]d=\sqrt{(-4-(-4))^2+(3-(-5))^2}[/tex]                [parenthesis]

[tex]d=\sqrt{(0)^2+(8)^2}[/tex]                                           [exponent]

[tex]d=\sqrt{0+64}[/tex]                                                   [add]

[tex]d=\sqrt{64}[/tex]                                                         [square root]

[tex]d=8[/tex]

------------------------------------------------------------------------------------------------------------

EF

[tex]d=\sqrt{(-8-(-3))^2+(2-2)^2}[/tex]                      [parenthesis]

[tex]d=\sqrt{(-5)^2+(0)^2}[/tex]                                        [exponent]

[tex]d=\sqrt{25+0}[/tex]                                                  [add]

[tex]d=\sqrt{25}[/tex]                                                        [square root]

[tex]d=5[/tex]

------------------------------------------------------------------------------------------------------------

After finding the distance of CD and EF, we can say that they are not congruent. The line CD is 8 units long and line EF is 5 units long. Therefore, they are not congruent.

Answer:

m=1

Step-by-step explanation:

step 1: 8(m + 2) = 3(12 - 4m) remove the parentheses

step 2: 8 m + 2 = 3 12 - 4m move the terms

step 3: 8m+ 12m= 36 - 16 collect like terms and calulate

step 4: 20m=20 divide both sides

solution: m=1

Answer:

m = 1

Step-by-step explanation:

To solve for m, we will have to get m by itself on one side, with some value on the other side.

8(m + 2) = 3(12 - 4m)

Distribute the 8 on the left side and the 3 on the right side.

8m + 16 = 36 - 12m

Add 12m to both sides.

20m + 16 = 36

Subtract 16 from both sides.

20m = 20

Divide both sides by 20.

m = 1

So now we have the answer m = 1.

Answer:

Brad's shadow is 3 feet long

Step-by-step explanation:

If a tree is 24 feet tall, and casts a shadow 12 feet long, The we know the shadows will be half as big as the main object.

Because Brad is 6ft tall, His shadow will be half of his hight (3ft long)

The slope of the tree to shadow is equal to the slope of Brad to shadow. The Brad's shadow is 3 ft long.

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function. The Pythagoras is the sum of the square of two sides is equal to the square of the longest side.

A tree 24 feet tall casts a shadow 12 feet long.

Brad is 6 feet tall.

The slope of the tree to shadow is equal to the slope of Brad to shadow (x). Then we have

[tex]\rm \dfrac{x}{6} = \dfrac{12}{24}\\\\x \ = \dfrac{6*12}{24}\\\\x \ = 3[/tex]

Answer:

8

Step-by-step explanation:

Let the number be n

6*n = 16 + 4*n

6n = 16 + 4n

6n - 4n = 16

2n = 16

2n/2 = 16/2

n = 8

Answer: There are several information's of immense importance already given in the question. Let us write them down first.

Diameter of the cylinder = 6 inches

Then

Radius of the cylinder = 3 inches.

Height of the cylinder = 3 * radius

                                  = 3 * 3

                                  = 9 inches

Volume of the cylinder = (pi) * (Radius)^2 * Height

                                   = 3.14 * (3)^2 * 9

                                   = 3.14 * 9 * 9

                                   = 254.34 cubic inches

Answer:

5

Step-by-step explanation:

The distance between the points (4,3) and ( 0,6) is; d = 5

The formula for distance between two coordinates is given as;

d = √((y2 - y1)² + (x2 - x1)²)

We are given the coordinates;

(4,3) and (0,6)

Thus;

x1 = 4

x2 = 0

y1 = 3

y2 = 6

Thus;

d = √((6 - 3)² + (0 - 4)²)

d = √(3² + 4²)

d = √25

d = 5
