Answer:

Step-by-step explanation:

y=mx+c

So in this case, m is (-3/7), which is the slope.

(-3/7)(another slope)=-1

Another slope=3/7

A. The slope is -7/3

B. The slope is 3/7

C. The slope is -7/3

D. The slope is -3/7

Thus, the answer is the bottom of the left hand side, which is 3x-7y=14

Hope it helps!!! Good luck!!

Step-by-step explanation:

$3 + \frac{9}{4} = \frac{9}{x+4} \\ \\ \therefore \: \frac{3 \times 4 + 9}{4} = \frac{9}{x+4} \\ \\ \therefore \: \frac{12 + 9}{4} = \frac{9}{x+4} \\ \\ \therefore \: \frac{21}{4} = \frac{9}{x+4} \\ \\ \therefore \:21(x + 4) = 36 \\ \\ \therefore \:21x + 84 = 36\\ \\ \therefore \:21x = 36 - 84\\ \\ \therefore \:21x = - 48\\ \\ \therefore \:x = \frac{-48}{21} \\ \\ \therefore \:x = \frac{-16}{7} \\ \\ \huge \red{ \boxed{ \therefore \:x = - 2 \frac{2}{7} }}\\ \\$

Answer:

Step-by-step explanation:

Measure of angle J K H + measure of angle J K L = 180 degrees

True.

Measure of angle J K L + measure of angle J L K + measure of angle K J L = 180 degrees

True. The sum of all interior angles = 180

Measure of angle J K H = measure of angle J L K =
