00 Which graph shows the solution to the system of
equations?
x+y=4
x - y = -2

The solution is (1, 3).

Step-by-step explanation:

Solving the second equation for x, we get x = y - 2.

Substituting y - 2 for x in the first equation, we obtain y - 2 + y = 4, or

2y = 6

Then y = 3.  

Substituting 3 for y in the 1st equation, we get x + 3 = 4, or x = 1.

The solution is (1, 3).

step-by-step explanation:

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
