Jacob and mark started taking a test at the same time. jacob finished his test 10 minutes before mark. which equation represents the time, j, jacob spent on the test compared to the time, m, mark spent on the test?

j=m-10

Step-by-step explanation:

If j respresentst he time Jacob spent in the test and m the time Mark spent on the test. We can write an expression that shows the amount of Time Jacob spent on the test compare to Jacob:

We know that Jacob finished the test 10 minutes before Mark.

Let j equal the Total time Jacob spent in terms of Marks time is:

Jacob spends m-10 on the test compared to Mark

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.
