To find that one, just look at the highest exponent. In the given equation that would be 4, so there can be at most 4 zeros in this function.
Step-by-step explanation:
the given function: 
Where C = cost (in dollars) and x is the number of miles you drive the truck.
when we compare the given function by slope- the intercept form y=mx+b, what we get is
Slope m = 0.5 whose fraction can be written as 
And y-intercept b =70.
for us to be able to graph it, we need to plot y-intercept from 70 and then plot some more points by applying or increasing the points by 
the shaded lines on the graph indicates the given function.
cost is at $70 for 0 number of miles. travelled.
Thus;
the Domain: x≥0 and Range :
≥
Answer:
19,500,000 hope it helps.
Step-by-step explanation:
Number of gallons remaining = Initial number of gallons - How much has been emptied
How much has been emptied = Emptying rate * Time period during which emptying occurs
Therefore:
How much has been emptied = 700t
Number of gallons remaining = 28000 - 700t
Answer:
x=260
Step-by-step explanation:
6/20 =78/x
We can use cross products to solve
6*x = 20 *78
Divide each side by 6
6x/6 = 1560/6
x =260
