Show your work, i have no idea how to do this

9. solve the exponential equation
1/16 = 64^(4x-3)

11. solve ln(5x + 7) = 8. round to the nearest thousandth.

12. use natural logarithms to solve the equation. round to the nearest thousandth.
5e^(2x+11) = 30

(that "e" is not a variable btw. it's e as in 2. i just wanted to make sure there was no confusion)

its kind of blurry. can you put a clearer pic?

step-by-step explanation:

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
