perpendicular = negative reciprocal
should multiply with -8 to give -1
-8x = -1
x = -1/-8
perpendicular slope = 1/8
(explanation: perpendicular lines have a slope that is the negative reciprocal and multiply with 8 to give -1)
parallel slope = 8
(parallel lines have the same slope)
Answer:
x = 7
Step-by-step explanation:
123 = 17x + 4
123 - 4 = 17x
119 = 17x
119 / 17 = x
7 = x
Answer: 65
Step-by-step explanation:
We know that her three tests are 69,65,77 so far
in order to get her average at 69 we need to do the following:
69+65+77+x=(69x4)
211+x=276
x=276-211=65
if she will get a 65 her average will be 69
