Three students are working together to complete a group project. They decided to share the responsibilities equally. Let x represent the responsibilities.

Write an expression to represent one group member’s share of the responsibility.

3x

cut 138 centimeters off

step-by-step explanation:

250-112 = 138

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.

answer: the answer is b. i think hope i got it correct

step-by-step explanation:

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
