5c=y. This is the equation represented in the statement.
We need to follow PEMDAS.
We need to do the division before we can do the subtract (which becomes into addition because of the signs).
12 - 16/-4
12 - (-4)
12 + 4
16
Your final answer is C. 16.
Answer:
D. p + q = 7
Step-by-step explanation:
The slope of AB is ...
mAB = (y2 -y1)/(x2 -x1) = (1 -4)/(6 -p) = -3/(6 -p)
The slope of BC is ...
mBC = (q -1)/(9 -6) = (q -1)/3
We want the product of these slopes to be -1:
mAB·mBC = -1 = (-3/(6 -p))·((q -1)/3)
-(q-1)/(6 -p) = -1 . . . . cancel factors of 3
q -1 = 6 -p . . . . . multiply by -(6 -p)
q + p = 7 . . . . . matches choice D
75-60=15
40+15=55 so Annette is 55 inches tall
