Alright so first he paid 45 for the guitar he resold it for 51.75(15% of 45 is 6.75) then spent 18.63(36% is 18.63)on books
I hope this helped...
You need to expand the brackets before you can simplify, so:
-3 × 10x = -30x
-3 × 4y = -12y
6 × 6x = 36x
6 × -2y = -12y
So now you have (-30x - 12y) + (36x - 12y)
-30x + 36x = 6x
-12y + -12y = -24y
So your answer is 6x - 24y. I hope this helps!
Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 5, - 17) and (x₂, y₂ ) = (- 5, - 3)
m =
= 
Since division by zero is undefined, then
the slope of the line is undefined
