Question

PLEASE HELP SOLVING LINEAR AND EXPONENTIAL EQUATIONS​ HELPPPP

Answer 1

Answer: D.

x≈33/8

Explanation:

`\left((3)/(2)\right)\left(-x+(15)/(2)\right)=u`

`-1=e^{(2u-15\ln \left((3)/(2)\right))/(2)}\left(-(2u-15\ln \left((3)/(2)\right))/(\ln \left((3)/(2)\right))-15\right)`

Answer 2

`\textbf{C. }\ x\approx(71)/(16)`

Explanation:

The graph shows the solution to be very near x = 4.5.

The offered choices are ...

A 4.312

B 4.375

C 4.438

D 4.125

The closest of these to 4.5 is choice C.

As the attachment shows, the value 71/16 is just shy of the actual answer of about 71.3/16.
