–4v – 9z – 9v + 2 – 4v find the sum

-1x(13v+9z+2)

Step-by-step explanation: try solve this :)

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
