Seth is driving to a friends house that is y miles away .after driving x miles in 4 hours, he still has 612 miles to go. the equation that relates y and x is . if he is driving at a speed of d miles per hour, the equation that relates x and d is

Step-by-step explanation:

speed x time = distance

s (1.5) = 105

1.5s=105

s = 70mph

d(t) = 70t

The equation that relates y and x is , and the equation that relates x and d is .

Step-by-step explanation:

Step 1: First we know that the total distance is equal to y. The distance traveled in 4 hours equals x, and the distance from point x to y equals 612 miles. Adding x to the remaining 612 miles gives the total distance y.

Step 2: To know the relationship between x and d, we must first raise the speed during the journey to x.

Then, we set the speed d e equal v:

Clearing x we get:

Have a nice day!

take it another

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
