Which of the following expressions has a value of 3? Select all that apply.
-6 ÷ -2
4 - (-1)
(-1)(-3)
(-2) - 1
15 ÷ -5
4 ÷ 1

the first one and the third one, negative three's don't count so don't put those in.

Step-by-step explanation:

-6 ÷ -2 = 3

4 - (-1) = 5

(-1)(-3)= 3

(-2) - 1 = -3

15 ÷ -5 = -3

4÷ 1 = 4

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

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.
