24x-24=180, my calculator said it was 12 and it was right but I don't understand how. My original answer was 8.5

It should be 8.5, idk how its wrong

Step-by-step explanation:

8.5

Step-by-step explanation:

ok so you take and add 24 to the -24 and the 180. The -24 cancels out sout its 204. 24x=204 then divide by 24 and thats your answer 8.5

idk

step-by-step explanation:

maybe try   if it is work from a book, if not try

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.
