The graph shows the speed of a blue car after the driver applies the brakes. The driver of a red car applies the brakes while traveling 30 miles per hour. The speed of the red car decreases at a constant rate until the car comes to a complete stop 4 seconds later. Compare the initial speeds and stopping times. (The speed of the blue car was 35 miles per hour and stopped at 3 seconds.)

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2

=240
