Answer:
-1/3
Step-by-step explanation:
y = 3x+7
This is in the form y = mx+b
The slope is m so it is equal to 3
Perpendicular lines have slopes that are negative reciprocals
m perpendicular = - (1/3)
D because it is a quadratic function
S= 5? that's at the top of my head
Answer:
21 weeks.
Step-by-step explanation:
To start, you have to get the pounds lost per week.
12/3=4
4 pounds lost per week.

4x=84
Divide 84/4=21
Therefore, it took 21 weeks to lose 84 pounds.

negative 24 minus 16x (-1) divided by 6^2 divided by 9
ANSWER
four divided by 81 and than X minus 24
