Answer:

$Y=(X-7)/2$

Step-by-step explanation:

we have

$X=2t+3$ -----> equation A

$Y=t-2$ -----> $t=Y+2$ -----> equation B

Substitute equation B in equation A

$X=2(Y+2)+3$

$X=2Y+4+3$

$X=2Y+7$

solve for Y

$2Y=X-7$

$Y=(X-7)/2$

$\displaystyle
F=\int \dfrac{4}{e^{4x}}\, dx\\
F=4 \int e^{-4x}\, dx\\
F=4 \cdot\left(-\dfrac{1}{4}e^{-4x}\right)+C\\
F=-e^{-4x}+C$
