The function
is a parabola concave up, whose solutions are
from here, you can use the quadratic formula
to find that the solutions of the parabola are 
So, the parabola is positive if 
(which wouldn't make sense in our case) or 
So, if Tanya caters 25 meals she breaks even, and starting with the 26th meal she will begin to profit.
Step-by-step explanation:
If we use this formula then
X is 54 y is 45
54 + 45 = 11(54 + 45)
99 = 11(99)
99 = 1089
= 1089 - 99
= 990
Slope is rise over run or change in y over change in x.
First, fourth and fifth choice
The correct simplification of the expression is 9c^2 i think.
Answer:
Y=2×+13
Step-by-step explanation:
2×+3=0
2×=0-3
you use 3 to divide it self =×
×=3
