((I've used 3.14 as pi))

Diameter = circumference / pi
= 4.5 / 3.14
= 1.43

Radius = diameter / 2
= 1.43 / 2
= 0.72

V = pi * r^2 * h
= 3.14 * 0.72^2 * 13
= 21.17
= B

Help!!! Question is attached. It is on Solving Equations.
kvv77 [185]
Hi there!

Okay, so we are solving for s. This is pretty simple. Just follow the steps below!

-10s = -8 - 9s

Step 1) Simplify both sides of the equation.

-10s = -8 + - 9s
-10s = -9s - 8

Step 2) Add 9s to both sides.

-10s + 9s = -9s - 8 + 9s
-s = -8

Step 3) Divide both sides by -1.

-s/-1 = -8/-1
s = 8

Our final answer is s = 8.

Hope this helps!

Answer: \Large\boxed{A.~y=3x+4}

Step-by-step explanation:

<u>Given information</u>

Slope = 3

Point = (-3, -5)

<u>Given the format of the equation</u>

Slope-intercept form: y = mx + b

  • m = Slope
  • b = y-intercept

<u>Substitute values into the equation</u>

y = (3)x + b

y = 3x + b

<u>Substitute the given point into the equation to get the value of [ b ]</u>

(-5) = 3(-3) + b

-5 = -9 + b

b = -5 + 9

b = 4

Therefore, the equation of the line is \Large\boxed{y=3x+4}

Hope this helps!! :)
