Slope is equal to change in y over change in x.

9-9/9-(-1)
0/10
0

Slope: 0

The slope is the change in y divided by the change in x.

so we have two points:
<span>(-1,9) and (9,9)

x1=-1
x2=9
y1=9
y2=9

and the slope = (y2-y1)/(x2-x1) = (9-9)/(9+1) = 0

Zero slope means this line is horizontal (parallel to the x-axis)

hope that helps

you rent a canoe for 5$ per hour.Your cost before the tax is added is 12.50. write and solve an equation to find the total numbe

Basile [38]

Answer: The equation is 5x = 12.50 and you will have the canoe for 2 and half hours or 2 hours 30 minutes.

Step-by-step explanation:

You rent the canoe for 5 dollars per hour and that can be represented by the expression 5x. After sometime you paid $12.50 meaning that to find the number of hours that you need the canoe, we need to set 5x to equal 12.50.

5x = 12.50 Solve for x by divide both sides by 5.

x = 2.5

This means you will need the canoe for 2 and half hours.

A farmer wants to fence in a rectangular field that encloses 3600 square feet. One side of the field is along a river and does n

andriy [413]

Answer:

C(x) = $\$3.50(\frac{x^2+7200}{x})$

Step-by-step explanation:

Data provided in the question:

Area of the field = 3600 square feet

Fencing charges = $3.50 per foot

Let the side along the river be 'x' feet and the other side of the 'B'

now,

Area of rectangle = Bx = 3600 square feet

B = $\frac{3600}{x}$ feet

and total length to be fenced = x + 2B

therefore,

Total cost of fencing = Fencing charges × total length to be fenced

Total cost of fencing = $3.50 × ( x + 2B )

substituting the value of B from (1)

Total cost of fencing, C(x) = $\$3.50(x+2\times\frac{3600}{x})$

C(x) = $\$3.50(\frac{x^2+7200}{x})$
