Use the formula for area of a triangle:
Area = 1/2 x base x height.
Fill in what you know:
40 = 1/2 x 20 x height
Multiply both sides by 2:
80 = 20 x height
Divide both sides by 20
Height = 4 m
For this case we have that the total of the balls is 86. We know there are 8 footballs then:
Basketball: Two more than twice the number of footballs are basketballs, that is:

There are 18 Basketballs.
Baseballs: Four less than 5 times the number of footballs are baseballs, that is:

There are 36 Baseballs.
Softballs: Six more than half of baseballs are softballs. That is to say:

There are 24 Softballs
If we add we must get 86.

ANswer:
There are 8 Footballs
There are 18 Basketballs.
There are 36 Baseballs.
There are 24 Softballs
Using proportions, it is found that he must have fewer at bats than Player A, as the batting average is inverse proportional to the number of at bats, hence you friend is incorrect.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
The batting average is given by the division of the number of hits by the number of at bats. Player B has fewer hits but a greater batting average, which means that he must have fewer at bats than Player A, as the batting average is inverse proportional to the number of at bats, hence you friend is incorrect.

I supose your function is:

Step 1. Replace the coordinates of the first point in your equation:
x=-2, y=3

Solve the equation for "a":

Step 2. Replace the coordinates of the second point in your equation:
x=6, y=35
Replace the value of "a" from Step 1.

Calculate "b":
![b= \sqrt[8]{\frac{35}{3}} = 1.359466](https://tex.z-dn.net/?f=b%3D%20%5Csqrt%5B8%5D%7B%5Cfrac%7B35%7D%7B3%7D%7D%20%3D%201.359466)
Step 3. Replace "b" in first equation and calculate "a":

The equation is:
-7x+2y=-13
x-2y=11
add them euations
-7x+2y=-13
<u>1x-2y=11 +</u>
-6x+0y=-2
-6x=-2
divide both sides by -6
x=1/3
sub back
x-2y=11
1/3-2y=11
minus 1/3 both sides
-2y=10 and 2/3
divide both sides by -2 (or times both sides by -1/2)
y=-5 and 1/3
x=1/3
y=-5 and 1/3
(1/3,-16/3)
