Which is the slope of a line that is perpendicular to the line represented by the equation x-y = 8
2 answers:
Answer:
-1
Step-by-step explanation: from the equation, x-y=8, make y the subject of the formulae , this gives - y= -x +8
divide all through by (-) sign, this gives y= x - 8
from the last equation above, the slope is the coefficient of x which is 1. since it is perpendicula, the answer is -1
by co efficient, we mean the number multiplying the unknown
Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange x - y = 8 into this form by subtracting x from both sides
- y = - x + 8 ( multiply through by - 1 )
y = x - 8 ← in slope- intercept form
with slope m = 1
Given a line with slope m then the slope of a line perpendicular to it is
= - = - = - 1 → D

The answer is 17/10 and 82/10
.394= 197/500
you can't make it a mixed number since there isn't a whole number as with an improper fraction.
Answer:
L = 18 inches
Step-by-step explanation:
if s is side length
400 = s•s•4
s² = 100
s = 10
so the original flat cardboard square has sides of
L = 10 + 4 + 4
L = 18 inches

70 is made up of 10*7
so first find 5*7 which is 35
35*10 is 350 so your answer is 350
