Very ez i’m just dumb fast i’m low on time

d =

Step-by-step explanation:

your equation, in the beginning, is t = dc - 2. they are asking you to find d, and that would mean that you have to isolate d to find its value. the first thing you do is add 2 to both sides to cancel it out on the right, so that, so far, leaves you with t +2 = dc. you still have c left on the right side with d, and since it's being multiplied with d, you'd have to divide it on both sides to cancel it out there. so you divide on both sides to move it to the left, and you are then left with your answer as:

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.
