State whether the pair of ratios form a proportion. dont guess fr + 23 POINTS 17/12 and 10/7

a. yes
b. no
c. cannot be determined

No

Cross multiply:

17 * 7 = 12 * 10

Simplifying

17 * 7 = 12 * 10

Multiply 17 * 7

119 = 12 * 10  

Multiply 12 * 10

119 = 120

Solving

119 = 120

Couldn't find a variable to solve for.

This equation is invalid, the left and right sides are not equal, therefore there is no solution.

answer: 2530

hope this

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.
