When solving an equation, Drew's first step is shown below. Which property justifies Drew's first step? Original Equation: 5(x + -5) = 4
First Step: 5x+−25= 4

1. addition property of equality
2.division property of equality
3.associative property of multiplication
4.distributive property of multiplication over addition

4.

Step-by-step explanation:

He starts off by distributing the 5 to the x and to the other 5.

This would be Distributive Property

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.
