Are the two expressions equivalent?
a. 4(8y - 8)
b: 32y - 32
no, because for y = 2, the value of expression a is 128 and the value of expression b is 32.
b.
yes, because for y = 2, the value of expression a is 32 and the value of expression b is 32.
c.
yes, because for y = 2, the value of expression a is 128 and the value of expression b is 128.
d.
no, because for y = 2, the value of expression a is 32 and the value of expression b is 128.

B

Step-by-step explanation:

Distribute 4 to all of the quantities in parentheses to get 32y-32

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
