Answer:
(1, 3) and (4,0)
Step-by-step explanation:
The quadratic function is 
We can rewrite in the form 
The graph is obtained by shifting the parent quadratic function 3 units right and 1 unit down to obtain the parabola shown in the attachment.
The straight line also have equation 
The slope is -1 and y-intercept is 4.
We can easily graph this straight line on the same graph as shown in the attachment.
The two graphs intersected at (4,0) and (1,3).
The solution set is therefore {(x,y)|x=4,y=0 or x=1,y=3}
You mean '39 is what percent of 12.5 ?'
So, the answer is
39/12.5 × 100
= 3.12 × 100
= 312%
So, 39 is 312% of 12.5.
(The percentage is greater because 39 is greater than 12.5)
1/3*3.14= 1.046666666 ect.
First you gave to get the denominators all the same then you can answer the questions
