Write the missing family
fact
5 x 16 = 80
80 : 5 = 16
16 x 5 = 80

  80 ÷ 16 = 5

Step-by-step explanation:

The "family facts" seem to be related to the relationship ...

  5 × 16 = 80

One of the facts is generated from this one by reversing the order of the factors:

  16 × 5 = 80

The other two are found by dividing the equation by one or the other of the factors:

  16 = 80/5 . . . . . divide by 5

  5 = 80/16 . . . . . divide by 16

This last one is the one that is missing. It the form used in the problem statement, it is ...

  80 : 16 = 5

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves

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.
