Annette rode her bike 6.8 miles at a constant rate for 90 minutes. to find how fast she traveled, she solved the equation 6.8=x·90 . what does x represent?

x represents the velocity of the bike.

Step-by-step explanation:

If velocity of a vehicle is multiplied by time, the distance that the vehicle goes can be found. Thus, Annette uses this formula to find her bikes velocity.

distance = velocity*time

x Represent velocity in this equation.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

the answer is 375 miles
