Answer-
C + 5 = x
C showing how many charms Jenny has on her bracelet.
5 for the number of how many more her sister has.
X for the final sum.
B because of you do 1/4 times -144 you will get 36 which is equivalent to 1/4x - 36

Given that d = 7 m


Answer:
256.4
Step-by-step explanation:
The line y = mx + c has a slope of m.
Parallel line:
A parallel line will also have a slope of m, and should be of the form
y = mx + k
Because the line passes through the point (a,b), therefore
ma + k = b
k = b - ma
The equation of a parallel line is
y = mx + b - ma
= m(x-a) + b
Perpendicular line:
A perpendicular line will have a slope of -1/m, because the product of slopes should be -1.
The equation for a perpendicular line is of the form
y = -(1/m)x + k
Because the line passes through (a,b), therefore
-(1/m)a + k = b
k = b + a/m
The equation for a perpendicular line is
y = -(x/m) + b + a/m
= -(1/m)(x-a) + b
Answer:
Parallel line:

Perpendicular line:
