Hey there! :)

Answer:

C. Both (2,1) and (4,9)

Step-by-step explanation:

To solve this question, simply plug in the coordinates of answer choices given into y = 4x - 7:

1 = 4(2) - 7

1 = 8 - 7

1 = 1. A is correct.

9 = 4(4) - 7

9 = 16 - 7

9 = 9. B is correct.

Therefore, the correct answer is C. Both (2,1) and (4,9) are solutions to this equation.

serious [3.7K]

Factor each number:
14=2*7
35=5*7

7 is a common factor, and no other (except 1), so 7 is the greatest common factor (GCF) of 14 and 35.

Crazy boy [7]

All together is - 60 cupcakes

Jim placed - 0.45 or 5 cupcakes

Dora placed - 10

Ada placed - 25% or 15

Kim placed the remaining and that is - 30

10 + 5 = 15 and 15 + 15 = 30 so Kim had 30 that means 30 + 30 = 60 cupcakes

Find the volume of a cylinder with base radius of 3 and height of 2

Lunna [17]

Answer:

Volume equals 56.6 when rounded to the nearest tenth

Step-by-step explanation:

YOU NEED A CALCULATOR TO SOLVE THIS!

To find the volume of a cylinder you need the formula $V = \pi r^{2}h$

Now that you have the formula you plug in the radius and the height

$V = \pi (3^{2}) (2)$

Then solve

$V = \pi (9)(2)$

$V = 18\pi$

$V = 56.548667764616278$
