The developers of a web site are tracking its number of adult users and teenage users. They found that the equation 56x + y = 795 models the number of teenage users over time, and the equation 161x − 2y = −154 models the number of adult users over time. In both equations, x is the number of years since 2000, and y is the number of users in thousands. During what year was the number of teenage users and adult users the same?

5/12, or 5: 12

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.

my computer is slow i can not see it sorry

b segment jm is correct i think
