Answer:

x = 31

m<ABC = 113

Step-by-step explanation:

The angles are supplementary.

x + 82 + x + 36 = 180

2x + 118 = 180

2x = 62

x = 31

m<ABC = x + 82 = 31 + 82 = 113

Answer:

x = 31

m<ABC = 113

What are the solutions of the following system? y=-2x^2 y=x-2
vovikov84 [41]

Answer:

x = 0.781 , y = -1.219

and

x = -1.281 , y = -3.281.

Step-by-step explanation:

Since both of the x terms are equal to y we can equate the x terms:-

-2x^2 = x - 2

2x^2 + x - 2 = 0

x = [-1 +/- √(1^2 - 4*2*-2) ] / 4

= ( - 1 +/- √(17)) / 4

= 0.781, -1.281.

When x = 0.781  y = 0.781 - 2 = -1.219.

when x = -1.281 , y = -1.281 - 2= -3.281.

What is the solution for the system of equations? 2y=4x-12 and y=-2x+2
pashok25 [27]

2y = 4x - 12 \\ y =  - 2x + 2 \\  \\ 2( - 2x + 2) = 4x - 12 \\  - 4x + 4 = 4x - 12 \\ 4 = 8x - 12 \\ 16 = 8x \\ 2 = x \\  \\ y =  - 2(2) + 2 \\ y =  - 4 + 2 \\ y =  - 2
