The slope of a line that is perpendicular to y = x - 6 means that the slope has to be a negative reciprocal of the original slope
That means the slope of the line that is perpendicular to y = x - 6 is '-1'
Hope that helps!
Answer:
14.04
Step-by-step explanation:
-
= 72
= 8.48
8.48 + 8.48 = 16.96
31 - 16.96 = 14.04
Answer:
(11, 13)
Step-by-step explanation:
Carolyn's work is incorrect. Below is the correct solution:
Given:
----› Equation 1
-----› Equation 2
Substitute y = (x + 2) in equation 1
----› Equation 1
(substitution)
(distributive property)
[Note: this is where Carolyn made a mistake]

Collect like terms

(addition property of equality).

Substitute x = 11 in equation 2
-----› Equation 2
(substitution)
✅The solution to the system of equations would be:
(11, 13)
Answer:
Step-by-step explanation:
x+y=26
x-y=9
by process of elemination
2x=35
x=17.5
17.5+y=26
y=8.5
Top is the passenger train
bottom is the freight
make sure you add 48+8=56
there are 56 trains that went to the station in a 12 hour period.
