It would take about 5 hours for them two to work together, because if you add 2+3 you will get 5 and they are asking in total.

Suppose $y_p=a_0+a_1t$ is a solution to the ODE. Then ${y_p}'=a_1$ and ${y_p}''=0$ , and substituting these into the ODE gives

$a_1-4(a_0+a_1t)=7t+5\implies\begin{cases}-4a_1=7\\-4a_0+a_1=5\end{cases}\implies a_0=-\dfrac{27}{16},a_1=-\dfrac74$

Then the particular solution to the ODE is

$y_p=-\dfrac{27}{16}-\dfrac74t$

Three roads, A, B and C, all run south to north. They each meet a highway that runs west to east. Road B is 4.6 mi east of Road

WITCHER [35]

Answer:

Road C is 1.5 mi east of Road A

Step-by-step explanation:

we know that

Road B is 4.6 mi east of Road A

Road C is 3.1 mi west of Road B

so

Road C is between Road A and Road B

AB=4.6 miles

CB=3.1 miles

AB=AC+CB

Solve for AC

AC=AB-CB

AC=4.6-3.1=1.5 miles

therefore

Road C is 1.5 mi east of Road A
