which expression is equivalent to (-7x + 8x 19y) - (6y + 8 -20x -16y) A. -19x -3y + 8 B. -19x + 9y + 8 C. 31x + 29y - 8 D. 35x + 19y - 8

can you make your screen more see able?

then i might be able to .

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
