A 2-column table with 5 rows. Column 1 is labeled Miles with entries 3.5, 7, b, 14, d. Column 2 is labeled Hours with entries 1, a, 3, c, 5. Margie can walk 3.5 miles in 1 hour.

Find the values of a, b, c, and d that complete the table showing this relationship.

a =
b =
c =
d =

step-by-step explanation

2r= 2300

r =1150

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
