Answer:
Option B. 
Step-by-step explanation:
we have
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
Graph 3x+2y=4.
3x+2y=4 3<span> x + 2 y = 4.</span>
Solve for y y .
<span>Since 3x 3 x does not contain the variable to solve for, move it to the right side of the equation by subtracting 3x 3 x from both sides.</span>
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.
15 posts plus 2 corner posts = 17 posts. With 17 posts there would be 16 spaces each side.
The space between each is 8 1/8 feet.
The length of one side is the number of spaces multiplied by the distance between each space.
Total length of one side = 16 spaces x 8 1/8 feet = 130 feet
Area = length x width.
It’s a square shape so area = 130 x 130 = 16,900 square feet
Perimeter is the distance around the square, this would be the length of one side x the number of sides.
Perimeter = 130 x 4 = 520 feet
If we remove the 2. The others will stay the same (roughly might move by 1) EXCEPT the range. Which will drop from 12 to 4
