Jamie is walking her neighbors’ dog while they are away. she is keeping track of the total number of blocks she walks over time. minutes blocks 6 3 14 7 20 10 does the table represent a proportional relationship? a) yes, because both columns are written in ascending order. b) yes, because the values in the second column are less than the values in the first column. c) yes, because the ratios are equivalent between each pair of values. d )no, because the values in the table do not increase by the same amount in each row.

Yes, because the ratios are equivalent between each pair of values.

I don't have an explanation, but this answer showed up on my test as the correct answer.

      Have a good day!

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

the answer i believe is 27 units.
