Step-by-step explanation:
4 -0 / -1 - -3.
4/2 = 2
m = 2 (slope)
Answer:
f(x) = sqrt(x + 6)
y = sqrt(x + 6)
x = sqrt(y + 6)
Stx^2 = y + 6
x^2 - 6 = y
red line: f(x) = sqrt(x + 6)
green line: f^-1(x) = x^2 - 6
He can buy 6 water bottles that are $3 a piece.
Width = W
Length = 12W - 1
Perimeter = 2L + 2W = 37
In the perimeter equation substitute the length equation in for L to get the equation in terms of W
2L + 2W = 37
2(12W - 1) + 2w = 37
Distribute
2(12W - 1) + 2w = 37
24W - 2 + 2w = 37
26W = 39
W = 3/2 = 1.5
Width = 1.5
Lastly, solve for length
L = 12W - 1
L = (12 • 1.5) - 1
L = 18 - 1
L = 17
Length = 17
If the line is vertical, then all of the point on the line have the same x-coordinate. In this case the x-coordinate is 1, so x=1.
