undefined
EXPLANATION
We want to find the slope of a line that is perpendicular to the line y = 1
The line y=1 is parallel to the x-axis.
In other words, the line y=1 is a horizontal line.
The line perpendicular to y=1 is a vertical line.
The slope of a vertical line is undefined
Answer:
40
Step-by-step explanation:
Ratio of cars to total:
32:80
so we can make another ratio with x
x:100
now make them fractions and cross-multiply
32/80 = x/100
32(100) = 80x
80x = 3200
x = 40
Answer:
5=4
Step-by-step explanation:
Use pemdas
A = 480
W = x
L = 11/5*x
therefore 480 = 11/5*x*x
480 = 11/5x^2
480*5 = 11x^2
2400/11 = x^2

However we can't have a negative width so width is

Sub this into the length equation to find length
-5+(-4)
-5-4
-9
Therefore, -9 is the correct answer
