x = √40

Step-by-step explanation:

The Pythagorean theorem formula is

+ =

step 1) divide 4 by 2 to get 2

+ =

step 2) plug 2 and 6 into the formula

+ =

step 3) multiply 2 by 2 to get 4

4 + =

step 4) multiply 6 by 6 to get 36

4 + 36 =

step 5) add 4 by 36 to get 40

40 =

step 6) take the square root of both sides of the equal sign (the √ cancels out the ²)

√40 = c

step 7) now you have the answer x = √40

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
