Answer:
h = 7
Step-by-step explanation:
Perhaps you want the solution to ...
1/(h -5) +2/(h +5) = 16/(h^2 -25)
Parentheses are required around denominators that have math operations.
Multiply by (h^2-25) and solve the linear equation.
Answer:
d) f(x) = 5x + 2
Step-by-step explanation:
First we need to identify the variables and how they fit into the equation. in this case we know that the equation is f(x) = mx + b where f(x) is the total cost, m is the hourly cost, x is the number of hours bowled, and b is the price of the shoes.
Now, we need to solve for the hourly cost, so to do this we plug in all the known information to get 12 = m(2) + 2
To solve we need to isolate the variable by first subtracting 2 on both sides to get 10 = m(2) and then dividing both sides by 2 to get 5 = m.
Finally, since we now know that the hourly cost is $5 we can plug this information back into the equation to get f(x) = 5x + 2

Answer:
<u>The correct answer is B. Exponential form.</u>
Step-by-step explanation:
The exponential form was developed to express repeated multiplications and to make it easier to write long numbers. The exponential notation has two parts. The base, as the name says, is the number below. The other part of the notation is a small number written on the superscript to the right of the base, called an exponent. We will use an example to learn about the exponential form or notation.
2³
In this example the base is 2. This means that 2 is a factor, and that it will be multiplied by itself a certain number of times. The precise number of times is given by the exponent, the number in the superscript. In this case, the exponent is 3, which means that base 2 will be used as a factor 3 times. So 2³ means 2 • 2 • 2 and the result is 8.
