Grace was driving down a road and after 4 hours she had traveled 66 miles. At this speed, how many miles could Grace travel in 8 hours? Fill out the table of equivalent ratios until you have found the value of x.

132 miles

Step-by-step explanation:

4 is half of 8 so you just have to multiple everything by 2 to get your answer

132

Step-by-step explanation:

Since in four hours you can travel 66 miles, 8 hours would be 66x2, which is 132.

1hour=16.5

2hour=33

3hour=49.5

4hour=66

5hour=82.5

6hour=99

7hour=115.5

8hour=132

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
