From the sum of 16 and -11 subtract the sum of -12 and 26

9

Step-by-step explanation:

At first, this question seems wordy, so let's break it down.

The sum of 16 and -11 is 16+-11, otherwise known as 16-11, which is 5.

The sum of -12 and 26 can be solved similarly to 26-12, or 14.

We want to subtract the first result from the second result, which would give 14-5, which equals 9.

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.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
