A student is solving a system of equations by substitution and comes up with the solution 3=3. Assuming that he solved the problem correctly, which of the following can be said about this system of equations?A) The system has exactly 1 solution.
B) The system has exactly 2 solutions.
C) The system has infinitely many solutions.
D) The system has no solution.

The answer to this is d

What is the solution of the system?Use the substitution method.

{y+7=3x
6x−2y=12

(14, 12)
(12, 14)
There is no solution.
There are an infinite number of solutions.

Answers

Answer:

Choice C) no solutions

=============================

Work Shown:

y+7 = 3x turns into y = 3x-7 after we subtract 7 from both sides

Plug that into the other equation and solve for x

------

6x - 2y = 12

6x - 2( y ) = 12

6x - 2( 3x-7 ) = 12 ... y replaced with 3x-7

6x - 2(3x) - 2(-7) = 12

6x - 6x + 14 = 12

0x + 14 = 12

0 + 14 = 12

14 = 12 ... this is a contradiction, aka false statement

------

No matter what x value we pick, the equation above will always be false.

Therefore, there are no solutions

We say that this system of equations is inconsistent.

Graphing both equations leads to two parallel lines. A solution only happens if the lines cross, but parallel lines never intersect.

Erica baby sits for 4 1/2 hours and is paid $27.A. How much does she make per hour?
B. How much does she make for 8 hours?
C. If the people she babysits for have $34 to pay her, how long can they stay out.

Answers

She makes $6 per hour. She makes $48 for 8 hours. She can babysit for 5.67 hours if she gets paid $34.

Erica babysits for 4 1/2 hours and gets paid for $27

The amount of money Erica earns in 1 hour is:

= (1 hour × $27 ) ÷ 9/2 hours

= ($27 × 2) / 9

= $6

The amount of money she makes in 8 hours is:

= 8 × $6

= $48

If the people she babysits for have $34 and the rate at which she's being paid per hour is $6, then the number of hours she can stay for is:

=(34 ÷ 6) hours

= 5.67 hours
