PLEASE HELP SOLVING LINEAR AND EXPONENTIAL EQUATIONS​ HELPPPP

Answer 1

Answer: D.

x≈33/8

Step-by-step explanation:

$\left(\frac{3}{2}\right)\left(-x+\frac{15}{2}\right)=u$

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

Answer 2

Answer:

  $\textbf{C. }\ x\approx\dfrac{71}{16}$

Step-by-step 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.
