Answer:

x=1

Step-by-step explanation:

First you would do the parentheses.

So, 4 x X= 4x

4x2=8

4x+8=2x+10

subtract 2x on both sides

2x+8=10

subtract 8 from both sides

2x=2

x=1

elixir [45]

Any integer can be written as a fraction! Just put that integer as the numerator of a fraction with a denominator of 1.

What is the equation for this graph pls help me and pls make sure it’s right:))

SVETLANKA909090 [29]

Answer:

y = 5x + 4

Step-by-step explanation:

First I found the slope by using the the definition that slope is rise/run so I saw that the y value went up from 4 to 9 which is 5 units and then the x value went up one in that same time. This means that the slope is 5/1. Then I found the y intercept by seeing where x = 0. On the graph you can see the line touches the y - axis at a value of 4 which means that the y - intercept is 4. Plugging these values into the y = mx + b equation you get y = 5x + 4.

Look at the formula for the volume of a cylinder below.

scZoUnD [109]

$h = V / ( \pi r^2)$

Okay, so we already have the volume equation for a cylinder here.
$V = \pi r^2 h$
Since we need to find the height(h), we need to basically isolate it in the equation. To do that we just have to divide both sides by (pi * r^2), where we end up with:
$V / (\pi r^2) = h(\pi r^2) / (\pi r^2)$
then
$V / ( \pi r^2) = h$
$h = V / ( \pi r^2)$
