Answer:
Step-by-step explanation:
The average cost for the training session provided he is a sports trainer can be computed as follows:
Let's assume that;
average cost = C(x)
the no. of session = x
Then:
Now, suppose the trainer wants the average cost C(x) to drop below $16;
Then, we have the following function:
By cross multiply:
120 + 15x ≤ 16x
120 ≤ 16x - 15x
120 ≤ x
Therefore, the required no. of session, if the average cost should drop below $16, is 120.

Given:
Total number of students = 1400
The ratio of boys to girls is 3 to 4 for the school.
To find:
The number of boys and girls.
Solution:
We have, Boy : Girls = 3:4.
Let number of boys be 3x and number of girls be 4x.
Total number of students = 1400
Divide both sides by 7.
Now,
Number of boys 
Number of girls 
Therefore, the number of boys is 600 and number of girls is 800 in the Berkmar Middle school.
Well they each have 3 solutions
The solutions to 7x-7y=-6 are:
- Slope=1
- X-intercept= - 6/7=-0.85714
- Y-intercept= 6/7= 0.85714
The answers to 13x-9y=16 are:
- Slope=2.889/2.000=1.444
- X-intercept=16/13=1.23077
- Y-intercept=16/-9=1.77778

Answer: -4x^2 + 8xy - 20y^2 + 12
Step-by-step explanation:
-4 (x2 - 2xy + 5y2 - 3)
-4(x^2) = -4x^2
-4(-2xy) = 8xy
-4(5y^2) = -20y^2
-4(-3) = 12
