Answer:
29 gallons
Step-by-step explanation:
Jacks car used 18 gallons of gasoline to go 468 miles.
we have to calculate the amount of gasoline would be used to go 754 miles.
∵ 18 gallons of gasoline were used to travel = 468 miles
∴ 1 gallon of gasoline were used to travel =
= 26 miles
∴ to cover the distance of 754 miles gasoline would be used =
= 29 gallons of gasoline
29 gallons of gasoline would be used to go 754 miles.

Answer:
D. Yes,because every x-value corresponds to exactly one y-value.
Step-by-step explanation:
The given ordered pairs are;
{}
We do not have the same x-value corresponding to more than one y-value.
We can see from the ordered pairs that every x-value corresponds to exactly one y-value.
Therefore the graph of this relation will pass the vertical line test.
Answer:
Step-by-step explanation:
Hello,
<em>"Ray says the third-degree polynomial has four intercepts. Kelsey argues the function can have as many as three zeros only."</em>
We know that Kelsey is right, a polynomial of degree 3 has maximum 3 zeroes, so it means that the graph of this polynomial has maximum 3 x-intercepts.
<u>So how Ray can be right too?</u>
we need to think of y-intercept, if we add the y-intercept then Ray can be right too,
as you can see in one example below
there are 3 x-intercepts and 1 y-intercept.
This being said, Ray is not always right. For instance
has only 1 zero (multiplicity 3) its graph has only 1 intercept in the point (0,0)
hope this helps
