Answer:
-4
Step-by-step explanation:
The slope of a function f(x) passing through two points of coordinates and
is given by
Therefore, in order to find the slope of the function h(x) of this problem, we have to find the coordinates of 2 points.
We know that h(x) has an x-intercept of 2: the x-intercept is the point where the function crosses the x-axis, so the coordinates of this point are
Because at x = 2, the value of y is zero.
We also know that h(x) has an y-intercept of 8: the y-intercept is the point where the function crosses the y-axis, so the coordinates of this point are
Because at x = 0, the value of y is 8.
Therefore, we can now use these 2 points to calculate the slope of the function:
Answer:
total cost = $ 81
Step-by-step explanation:
It is given that the fixed cost is $ 39
and the cost per minute is $0.07
Let us assume the number of minutes used be x
we have
total cost = cost per minute × number of minutes used + fixed cost
we plug the given values, so we have
we need to find the total cost for 10 hours used
x= 10 hours = 10(60) minutes = 600 minutes
so we have total cost for x= 600 minutes
hence the total cost = $ 81
