Answer:

(0,2)

Step-by-step explanation:

7x - 4(4x + 2) = -8

7x - 16x - 8 = -8

-9x = -8 = -8

-9x = 0

x = 0

y = 4(0) + 2

y = 2

The subtraction function

$(k-x)(x)$

is defined as the subtraction of the two equations, representing each function:

$(k-h)(x)=k(x)-h(x)$

So, we have

$(k-h)(x)=k(x)-h(x)=14x-2-(2x^3+4x-8)=-2x^3+10x+6$

Answer:

Step-by-step explanation:

The two x angles on the right are supplementary which means they add up to 180 degrees

5x + 12 + 7x - 24 = 180

12x - 12 = 180

12x = 192

x = 192/12

x = 18

5x + 12 and y are corresponding angles and are therefore equal

5(18) + 12 = 90 + 12 = 102

Therefore y = 102
