Answer:
option B
(−1, 0) and (0, 6)
Step-by-step explanation:
Given in the question two equations,
Equation 1
y =−x² + 5x + 6
Equation 2
−6x + y = 6
plug value of y in second equation
−6x −x² + 5x + 6 = 6
-x² -6x + 5x +6 - 6 = 0
-x² - x + 0 = 0
-x² -x = 0
-x(x+1) = 0
x = 0
and
x = -1
plug value of x in second equation to find y
x = 0
−6(0) + y = 6
0 + y = 6
y = 6
and
x = -1
−6(-1) + y = 6
6 + y = 6
y = 0
Answer: Lucy ate more pizzas because he ate more inches of pizza than Anthony.
Step-by-step explanation:
Anthony eats 2 slices of a large 18 inch pizza. Total number of slice in the 18 inch pizza is 8
The size of one slice in inches would be total length of pizza / number of slices. It becomes
18 / 8 = 2.25 inches
Anthony ate 2 ×2.25 = 4.5 inches of pizza.
Lucy eats 4 slices of a 12 inch pizza.
Total number of slice in the 12inch pizza is 8
The size of one slice in inches would be total length of pizza / number of slices. It becomes
12 / 8 = 1.5 inches
Lucy ate 4 × 1.5 = 6 inches of pizza.
Lucy ate more pizzas because he ate more inches of pizza than Anthony.
f(x) = 10x + 50
multiply the cost per person by 5 ( you and 4 friends )
f(x) = 5(2x + 10) = 10x + 50
