Answer:
a. <u>y = $3 + $2.50x,</u>
b. <u>$23</u>
Step-by-step explanation:
y is the total cost of x gallons of gasoline at $2.50/gallon.
a. The total cost of one car wash ($23 each) plus x gallons of gas is:
<u>a. y = $3 + $2.50x</u>
<u></u>
b. The cost of a car wash and 8 gallons (x=8) is:
b. y = $3 + $2.50*(8)
y = $3 + $20
<u>y = $23</u>
Answer:
6
Step-by-step explanation:
Therefore,
Answer:
The answer is C) .
Step-by-step explanation:
For a real number ,
.
In other words, multiplying a square root by itself gets rid of the square root.
How does this rule apply here?
.
Similarly,
.
That is:
.
The rational function shown in the graph is:
<h3>
How to determine the function?</h3>
First, we can see that we have an asymptote at x = 5, so the denominator becomes equal to zero when x = 5.
Then the rational function is something like:
We also can see that when x = 6, the function intercepts the x-axis, then we must have that:
g(6) = 0
So we can define:
g(x) = x - 6
So the rational function is:
