Solve the equations 4× + 4 = 20. Write the problem on the sketch pad then solve the problem algebraically. I need shown work.

x = 4

Step-by-step explanation:

I don't know what you mean by sketch pad but here is the working out

4x + 4 = 20

-4            -4

4x = 16

÷4           ÷4

x = 4

Hope this helps :)

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
