Reverse the table and observe
- For 1 month cost is 50
- For 2 months the cost is 100
See the pairs are (1,50) and (2,100) and so on
We know domain is set of x values and range is set of y values.
As there is no extra cost and the cost is 50$ per month cost depends upon the month means months are independent and cost is dependent , months are x and cost will be y then
The equation is
So here domain is all months
- {1,2,3,4,5,6,7,8,9,10,11,12}
We already know PM is perp. to MO, so we know ang. m = 90
90 + 30 = 120
m P = 60
The values are 
The quadratic function, expressed in factored form is
Expanding and simplifying
since
we can equate coefficients of like-terms and conclude that

Answer:
The answer is b.
Step-by-step explanation:
The line reflected with the axis only changes the position, and will not change the size. If reflected with y-axis, AB moves left of the y-axis lying x= -1 to x= -5.
A'B' will not be perpendicular unless you rotate at some point for 90 degrees.
Answer: -3
Steps: 12 - 3√25
3 √25 = 15
12 - 15
Subtract the numbers: 12 - 15 = -3
