Travis traveled 315 miles in 5 hours. what is his unit rate of speed in miles per hour?

63 miles per hour

20character limit is silly

D(distance) r(rate) t(time)
Formula to use: d=r*t
however, you are looking for the r (rate) so we need to rearrange the formula to r=d/t.

Now plug in what you know: r=315 miles (d)/ 5 hours (t)= 63 mi/hr

Translate each point of the graph of h(x) 3 units left ⇒ 4th answer

Step-by-step explanation:

Let us revise the translation of a graph

If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)  If the function f(x) translated horizontally to the left by h units, then its image is g(x) = f(x + h)  If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k  If the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k  

∵

∵  

∵ x in h(x) is changed to (x + 3) in m(x)

- From the 2nd rule above, that means the graph of h(x)

   is translated 3 units to the left

∴ The graph of h(x) is translated 3 units to the left

∴ Each point on the graph of h(x) is translated 3 units to the left

∴ Translate each point of the graph of h(x) 3 units left

Look to the attached figure to more understand

The red line represents h(x)

The blue line represents m(x)
