Answer:
y=-2x+2
Step-by-step explanation:
Given line is-
x-2y=7
we know,
equation of line perpendicular to ax+by=c is bx-ay=k
So, equation of line perpendicular to x-2y=7
is given by -2x-y=k
Now, the line -2x-y=k passes through (5,-8)
So, we get
-2(5)-(-8)=k
or, -10+8=k
or, -2=k
So, k=-2
Using the k value we get,
Equation of the line is-
-2x-y=-2
multiplying by -1
2x+y=2
or, y=-2x+2
This is the slope intercept form of the line.

Answer:
12 1/4
Step-by-step explanation:
(7 + X) × 8 - 4 × X = 56
7 + X × 8 - 4 × X = 56
7 + 8X - 4 × X = 56
7 + 8X - 4X = 56
7 + 4X = 56
4X = 56 - 7
X = 49/4
X = 12 1/4
