Which quadratic rule represents the data in the table? x –1 0 1 2 3
y –4 –5 –4 –1 4

A. y = –2x² + 5
B. y = –x² + 5
C. y = x² – 5
D. y = x² + 5

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

the answer is $42.96

step-by-step explanation:

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
