could I by any chance get a brainliest?
Answer:
x=6
y=-3
Step-by-step explanation:
<em><u>solve for x-</u></em>
-4x+8y=-24 replace y with 0
-4x+8(0)=-24
-4x=-24 divide by -4 on both sides
x=6
<u><em>Solve for y-</em></u>
-4x+8y=-24 replace x with 0
-4(0)+8y=-24
8y=-24 divide by 8 from both sides
y=-3
Answer:
y=3.5x+4; A(_,5) B(10,_)
Step-by-step explanation:
.Find point A: Substitute y value given, solve for x:
.
5=3.5x+4
1=3.5x
1/3.5=x
0.2857=x
.
Point A=(0.2857,5)
.
Find point B: Substitute x value given, solve for y:
.
y=3.5(10)+4
y=35+4
y=39
.
Point B=(10,39)
.
Slope:
In slope intercept form y=mx+b, m=slope
.
Slope=m=3.5
.
The others are done the same way.

Answer:
x - 8>-4-x
Step-by-step explanation:
Looking at x - 8>-4-x
Collect the like terms;
x+x > -4 + 8
2x < 4
x > 4/2
x < 2
Since the values of x are greater than 2,this shows that they are positive values and will be farther from -8 than -4
