In 2 1/4 hours, Nick wrote 36 text messages what’s was his unit rate during the time? A.14 messages per hour

B.16 messages per hour

C.34 messages per hour

D.81 messages per hour

A. 224 messages per hour

B. 256 messages per hour

C. 544 messages per hour

D. 1296 messages per hour

Step-by-step explanation:

First you need to figure out how many messages Nick wrote in 1 hour

36 messages÷ 2.25

2.25 hours÷ 2.25

=

16 messages

1 hour

=

16 messages

hour

Then you multiply how ever many hours by 16 because Nick can write 16 messages in 1 hour.

i would pic false cause it goes down towards negative

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.
