Answer:
Step-by-step explanation:
The max value of the sine function is 1.
If we multiply it by 2, we get 2 sin x, whose max. value is 2.
If we multiply the sine function by -2, the max value of this functin is still 2.
36.64-21=15.64
15.64-6.14=9.5
The answer is she made $9.50 worth in local calls last month

Answer:
The axis of symmetry is x = 6
Step-by-step explanation:
To find this, first find the two x-intercept values and then take the average. This will always be the line of symmetry.
x + 9 = 0
x = -9
x - 21 = 0
x = 21
Now take the average of these two numbers.
(-9 + 21)/2
12/2
6
