Answer:

$675

$850

$1200

Step-by-step explanation:

Use formula for simple interest:

A = P (1+rt)

where

A = accrued amount (principal + interest) = what we want to find

P = Principal (initial) amount = Given as $500

r = rate of interest = Given as 7% = 0.07

t = time

For 5 years, t = 5

A = 500 [ 1 + 0.07(5) ] = $675

For 10 years, t = 10

A = 500 [ 1 + 0.07(10) ] = $850

For 20 years, t = 20

A = 500 [ 1 + 0.07(20) ] = $1200

Consider the following system of equations:
Inga [223]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

"Line y = −2x + 3 intersects line y = x − 5."  

»»————- ★ ————-««  

Here’s why:  

  • When the system of equations are graphed, they would intersect at a point.
  • This means that there is a solution to the system. The solution is (\frac{8}{3} ,-\frac{7}{3} ).
  • While the statement that the lines intersect the x-axis is true, the question asks the statement that describes the <em>solution</em>.
  • The solution is the point of intersection between the two lines.

Hope this helps you. I apologize if it’s incorrect.
