Answer:
Edward is correct
Step-by-step explanation:
When denominator =0 , then the function becomes undefined
Now we look at the values of x that makes the denominator 0
We set the denominator =0 and solve for x
(x+1)(x-2)(x-4) =0
x+1=0 so x= -1
x-2=0 so x=2
x-4 =0 so x=4
x=-1 , 2 and 4 makes the denominator 0. that is undefined
So Edward is correct
The slope of y = -x is m = -1. Thus, starting with the slope-intercept form y = mx + b, we substitute -1 for m, 8 for x and 2 for y, to determine the vaue of b:
2 = -1(8) + b, or 10 = b. Then the equation of the line parallel to y = -x and passing thru (8,2) is:
y = -x + 10.

The length of a rectangular patio is 4 feet less than three times it's width. The area of the patio is 160 square feet. Find the dimensions of the patio.
Answer:
see below
Step-by-step explanation: 5 20 15 28
3x + y = 23
3x – 2y = 8
O I should add, and the Xs will be eliminated. 3x + 3x = 6x NOT eliminated
O I should add, and the Ys will be eliminated. y + -2y = -y NOT eliminated
O I should subtract, and the Xs will be eliminated. 3x - 3x = 0x X is eliminated
O I should subtract, and the Ys will be eliminated. y - -2y = y NOT eliminated
