Jessica wanted to know how much farther she ran in Week 2 than in Week 1. Her work is below. 15.05 minus 11.90 = 5.95. The decimals in the equation are all aligned. The 0 in 15.05 is crossed out and a 10 is above it. The first 5 in 15.05 is crossed out and a 6 is above it.

What mistakes did Jessica make when solving the problem? Select all that apply.
She did not align the decimal points.
She did not subtract 10 and 9 correctly.
She subtracted instead of adding.

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

2/4 is the answer

step-by-step explanation:

x= total pieces

both ate 9 pieces

mindy ate 3 so troy ate 6

6= (1/4)x

x =24
