Answer:

Step-by-step explanation:

Let's look at the first equation first, y = -2x -1. We know its y-intercept is at -1, so if there isn't a line on the graph that intersects at -1, we can cross it of. This means B and C can't be the answers.

Let's now look at the slope of that same equation. It's negative, so it must be going left to right (like this: \ not like this: /).

Only graph D has a line that goes through -1 on the y-axis and has a negative slope!

Answer: $352.48

Step-by-step explanation:

Hi, to answer this question we have to apply the formula:

A = P (1 + r)^t

Where

A: total balance after invest

P: principal amount invested

r = interest rate (in decimal form)

t = time (years)

Replacing with the values given:

500= P (1+0.06)^6

Solving for P:

500 = P (1.06)^6

500 / ( (1.06)^6)=P

500 / 1.4185 =P

$352.48= P
