Answer: c is perpendicular to y = -5x - 2

Explanation: The slope of a perpendicular line is an opposite reciprocal of the original slope/line. (Basically switch the numerator and denominator and the sign. In this case, the slope is -5/1x. It’s opposite reciprocal is 1/5x.)

You can take a look at my notes for further clarification. Hope this helps!

20. Determine the following product. 5g(-3g²h - 7g + 9)

soldier1979 [14.2K]

Distribute 5g to all of the terms in parentheses:

$5g \times -3g^2h = -15g^3h$
$5g \times -7g = -35g^2$
$5g \times 9 = 45g$

$-15g^3h - 35g^2 + 45g$

The answer is A.
