(5, 35) and (1,7)
unit rate = (35 - 7)/(5 - 1)
= 28/4
= 8
Answer
8 mpg
Let:
Ms. Barton = b
Mr. Weaver = b + 8
Mr. Fitzgerald = 2b - 15
Mr. Lloyd = 1/2b + 30
Find b:
176 = b + b + 8 + 2b - 15 + 1/2b + 30
176 = 9/2b + 23
153 = 9/2b
b=34
Plug in 9 to b:
Ms. Barton = 34 slices (4th place)
Mr. Weaver = 34 + 8 = 42 slices (3rd place)
Mr. Fitzgerald = 2(34) - 15 = 53 slices (1st place)
Mr. Lloyd = 1/2(34) + 30 = 47 slices (2nd place)
Answer:
Step-by-step explanation:
y = ax² + bx + c
Plug the points into the equation to get a system of 3 equations with 3 unknowns a, b, and c.
-27 = 4a - 2b + c
-42 = 9a + 3b + c
-12 = a + b + c
(a,b,c) = (-4,1,-9)
y = -4x² + x - 9
Answer:
6-10b
