Willis analyzed the following table to determine if the function it represents is linear or non-linear First he found the differences
in the y-values as 7 - 1 = 6, 17 - 7 = 10 and 31 - 17 = 14. Then he concluded that since the differences of 6, 10, and 14 are
increasing by 4 each time the function has a constant rate of change and is linear What was Willis's mistake?

He found the differences in the y-values as 7 - 1 = 6, 17 - 7 = 10 and 31 - 17 = 14
He determined that the differences of 6. 10. and 14 are increasing by 4 each time
He concluded that the function has a constant rate of change
He reasoned that a function that has a constant rate of change is linear

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.
