Always try to simplify prior graphing. However you have to mention where the function is continued or discontinued.

We notice that the numerator is a quadratic equation. Is roots are :
x = -2 and x" = 10
Then the numerator could be written (x+2)(x+10) and the function:
y= (x+2)(x+10)/(x+2). Prior to simplifying, you should notice that this function is discontinued for x = -2 (doesn't exist), so the domain is all x# -2.
Now you simplify and you will get:
y = (x-10) , which is a linear function, but cannot be at x = -2

<h3><u>Answer</u> :</h3>

\sf \dashrightarrow \dfrac{22}{7} \div \dfrac{22}{7}

\sf \dashrightarrow \dfrac{22}{7} \times \dfrac{7}{22}

\sf \dashrightarrow \dfrac{\cancel{22}}{\cancel{7}} \times \dfrac{\cancel{7}}{\cancel{22}}

\sf \dashrightarrow 1 \times 1

\sf \dashrightarrow 1

The Thompson family is buying a car that can travel 70 miles on two gallons of gas. Assume that the distance traveled in miles y
artcher [175]
70/2 = 35

The car gets 35 miles per gallons.

You can also find that out by looking at the slope of the equation. y = 35x. 35 is the slope here.

For your graph, plot the points:
(0,0)
(1,35)
(2,70)
(3,105)
(4,140)
(5,175)
(6,210)
(7,245)
(8,280)

And then draw a line through the points.
