Question

Can someone check a few answers for me?

:)

Answer 1

QUESTION:

An equation is shown below:

9x - y = -2

Part A: Explain how you will show all of the solutions that satisfy this equation. (4 points)

Part B: Determine three different solutions for this equation. (4 points)

Part C: Write an equation that can be paired with the given equation in order to form a system of equations that is inconsistent. (2 points)

ANSWER:

Part A:
9x - y= -2
solve for y and add y to both sides
9x= -2 y
add 2
9x 2 = y
There are infinite number of solutions to the equation.

Part B:
9(2) 2 = y
18 2 = 20
x= 2
and
y= 20

9(3) 2 = y
27 2 29
x= 3
and
y= 29

9(4) 2= y
36 2 = 38
x= 4
and
y= 38

Part C:
9x-y = 5 is an example because there is no x or y values that can both be 5 or -2 at the same time.

Answer 2

It looks good to me, but you probably want a second opinion.

Answer 3

Okay thank you.
