The answer is C, from where the end lines go down to on the graph
Answer:
C = 15 + 0.11y
Step-by-step explanation:
Let us assume that Hannah utilizes x kilowatt-hour of electricity per month.
The electricity company charges $ 0.11 per kilowatt-hour of electricity uses and plus a basic connection charge of $ 15.
Therefore, the linear function that models her monthly electricity bill (C) as a function of electricity usage (y) will be
C = 15 + 0.11y {Hence, C will be a linear function of y} (Answer)
Squ((20a^6)(b^3))
2(a^3)(b)squ(b)
Answer:
For the first one:
y = 2/3x + 1
For the second one:
y = -5x + 4
Step-by-step explanation:
As you may already know, in the y=mx+b equation format:
m = slope
b = y-intercept
On the graph, it already shows the y-intercept, so you can automatically find your b in the equation.
And, the easiest, most quick way to find the slope by using a graph is to calculate using rise/run. So, by doing that you can calculate the equation.
Then, you can just leave the variables y and x alone.

Using the side of the square find the area:
Area = 30^2 = 900 square feet.
The rectangles area is the same, 900 square feet.
Let the width = X
The length would be 2X + 70
Area = length x width
X * 2x+ 70 = 900
This expands to 2x^2 * 70x = 900
Use the quadratic formula to solve for x:
-70 +/- sqrt(70^2-4*2(-900))/2*2
X = 10
Width = x = 10 feet
Length = 2x + 70 = 90 feet
