Help??????????????????
Neko [114]

Answer:

40

Step-by-step explanation:

52= 1/2(64 + x)

52 = 32 + 0.5x

52-32= 32-32 + .5x

20=.5x

Divide both sides by .5x

X = 40.

How do you graph an equation using x and y intercepts.
Citrus2011 [14]

Answer:

I'm going to use the following as an example.

2x + 4y = 8

To find the y-intercept, set x equal to 0 then solve for y.

2(0) + 4y = 8

two times zero is zero, so we have the following equation.

4y = 8

Solve for y

\frac{4y}{4}  =  \frac{8}{4}  \\ y = 2

Your first point you will graph is (0, 2).

Now solve for the x intercept. To do this, set y = 0.

2x + 4(0) = 8

4(0) = 0, so you can remove it, and solve for x.

2x = 8

\frac{2x}{2}  =  \frac{8}{2}  \\ x = 4

Now the next point you have is (4, 0). plot that point. Connect the two points with a line and you are done.
