C = hours Carlos drove, M = hours Maria drove.
52*C+54*M = 217
C = 4,1-M
52*(4,1-M)+54M = 217
213,2-52M+54M = 217
217-213,2 = 54M-52M
3,8 = 2M
M = 1,9
Maria drove 1,9h.
(-4)⁴ = (-4)*(-4)*(-4)*(-4)
= [(-4)*(-4)] * [(-4)*(-4)]
Because (-4)*(-4) = 16, therefore
(-4)⁴ = 16*16 = 256
Answer: 256
5/8
5*5=25
8*8=64
25/64 inches ^2
Option B:
<u>Solution:</u>
<u>Slope of the perpendicular lines:</u>
If two lines are perpendicular then their slopes are negative reciprocals of each other.
<u>Slope of the parallel lines:</u>
If two lines are parallel then they have the same slope.
i.e their slopes are equal.
Given line m and p are parallel.
Slope of the line m =
Using slope of the parallel lines definition,
Slope of the line p = slope of the line m
Slope of the line p =
Option B is the correct aswer.
Hence the slope of the of line p is .
