Answer:
No.
Step-by-step explanation:
A function must pass the Vertical Line Test. The equation given is a circle on the coordinate plane. Therefore, since there will be 2 points for the same <em>x</em> value, it will not be a function.
I wpuld say B...because that can be the one Delta planet
The answer is $84.29
Let the number of minutes be x.
$35.99 is fixed price and does not depend on the number of minutes x. Each minute costs $0.21 so it depends on x and we have 0.21x in the function. However, 250 minutes are already included and should not be included in x. Therefore, the function that represents the monthly cost looks like this:
f(x) = 35.99 + 0.21 * (x - 250)
Now, let's calculate for x = 480 minutes:
f(480) = 35.99 + 0.21 * (480 - 250)
f(480) = 35.99 + 0.21 * 230
f(480) = 35.99 + 48.30
f(480) = 84.29
Answer:
d has is the graph with the slope of 1/2.
Step-by-step explanation:
the rise over run from point to point is how you determine the slope.
i hope this helps :)
