Question

Can you check my answers. Please and thank you!

Simplify the following expression.
8x - 8y + 5z - 3x - 14y + 3z

11x - 22y + 8z

5x - 6y + 8z

5x - 22y + 8z

11x - 6y + 8z

I chose C.

Evaluate: -8 - (-3)

-11

-5

I chose C.

What is the slope and y-intercept of the graph of 2x + 3y = 18?

slope = -2; y-intercept = (0, 18)

slope = -2/3; y-intercept = (0, 6)

slope = -3/2; y-intercept = (0, 2)

slope = 6; y-intercept = (0, )

I chose B.

Answer 1

double check number 2

Answer 2

and #3

Answer 3

Can you explain to me how to do them?

Answer 4

-(-3) = ?

Answer 5

the third question can be soved by writing the equation in the form y = mx + b
where m is the slope and c - y-intercept

Answer 6

* and b = y-intercept

Answer 7

Okay thank you!

Answer 8

Could you help me on another?

Answer 9

2x + 3y = 18
3y = -2x + 18
divide both sides by 3:

y = (-2/3) x + 6

slope = -2/3 and y-intercept = (0,6)

Answer 10

no gotta go
but look again at question 2 and what completeidiot has written

Answer 11

okay thanks
