Answer:

7x - 8y = -23

Slope = 1.750/2.000 = 0.875

x - intercept = -23/7 = 3.28571

y - intercept = 23/8 = 2.87500

7x - 7y = -14

Slope = 1

x - intercept = -2/1 = -2.00000

y - intercept = 2/1 = 2.00000

Noelle and karina both leave the Internet cafe at the same time, but in opposite directions. If karina travels 9 mph faster than
Vesna [10]
Noelle goes east at N mph.
Karina travels west at N + 9
then their velocity between them is (N + N + 9)
After 8 hours they travel 8(2N + 9) = 232
(2N + 9) = 29
2N = 20
N = 10 mph for Noelle
N+9=19 mph for Karina

trasher [3.6K]

There are 30.48 centimeters in 12 inches.

Step-by-step explanation:

Given,

1 inch = 2.54 centimeters

For x inches;

x inches = 2.54*x centimeters

x inches = 2.54x centimeters

Number of centimeters in 12 inches

What is -x/3 = 9. Solve for x
vlada-n [284]

Note: I just noticed that you only have one negative sign. If you mean to put -9, change the sign to positive. If not, leave the answer.

Note the equal sign. what you do to one side, you do to the other. Isolate the x. First, multiply 3 to both sides

-x/3(3) = 9(3)

-x = 9(3)

-x = 27

Next, to isolate the x, divide -1 from both sides

-x/-1 = 27/-1

x = 27/-1

x = -27

-27 is your answer for x.

hope this helps

When looking at the net of a cylinder, what is the relationship between the height of the rectangle and the cylinder?
Nastasia [14]

Volume of a cylinder = πr²h

where,

r is the radius of the cylinder

h is the height of the cylinder

Area of the rectangle = length X breadth

We can consider that a rectangle if rotated will form a cylinder.

In that case, the breath of the rectangle will become the diameter of the cylinder and the length will become the height of the cylinder.
