Answer:
x=-5, y=-8. (-5, -8).
Step-by-step explanation:
-x+2y=-11
5x-8y=39
---------------
5(-x+2y)=5(-11)
5x-8y=39
---------------------
-5x+10y=-55
5x-8y=39
--------------------
2y=-16
y=-16/2
y=-8
-x+2(-8)=-11
-x-16=-11
-x=-11+16
-x=5
x=-5
Answer:
104 Pages
Step-by-step explanation:
on Monday she reads 3/8 of the novel which means
x 352 = 132 pages
on Tuesday she reads 28 pages, doesn't require any calculations.
on Wednesday she reads 1/4 of the novel,
x 352 = 88
Just add all of that,
132+28+88=248 Pages
Subtract the novel pages by the read pages value
352-248=104pages.

Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (2, 4) ← 2 points on the line
m =
