Answer:
Step-by-step explanation:
The general equation is
y = 2.49x + 24.99
The number of cones bought is x
The cake cost is 24.99
The total cost is y
===========
So the meaning of (5,37.44) is that she bought 5 cones and 1 cake. Let's just check that out.
Check
y = 2.49*5 + 24.99
y = 12.45 + 24.99
y = 37.44
So the total cost (y) of 5 cones (2.49 each) and 1 cake ($24.99) is 37.44
Answer:
1. (-125 a - 5.75) x + b c (605 x - 550 x^2) + 10.75
2. -125 a x + x (-550 b c x + 605 b c - 5.75) + 10.75
3. 0.25 (-500 a x - 220 b c (10 x - 11) x - 23 x + 43)

Answer:
equation of circle is (x+5)^2+(y-3)^2=16
Step-by-step explanation:
equation of circle ](https://tex.z-dn.net/?f=%28x-x_1%29%5E2%2B%28y-y_1%29%5E2%3Dr%5E2%3C%2Fp%3E%3Cp%3Ewhere%20r%3Dredius%20of%20circle%2C%5Btex%5D%28x_1%2Cy_1%29)
is centre of circle
centre of circle=(-5,3)
put the value of centre and redius in the equation
equation of circle 
=4^2
Same number of rows to chairs in a row would form a square.
Use the total number of students as the area
Find the number or rows by taking the square root of student:
The square root of 7033 is 83.86
Round up to 84
Total seats would be rows x seats per row:
84 x 84 = 7,056 total seats
7056 seats - 7033 students = 23 empty seats
