Anthropologists use the length of certain bones of the human skeleton to estimate the height of the living person. One of these bones is the femur. To estimate the height in centimeters of a female with a femur length of x, the function h(x) = 61.41 + 2.32x can be used. If a 46 cm femur bone is discovered at a dig site, using the height function, estimate how tall the person was that bone belonged to.

What is f(2) for the function f(x) = 4x + 1?
What is the graph of the function rule?
Be sure to include relevant graph detail: label axes, indicate units on both axes, and use arrows to represent end behavior, as appropriate.
The function rule below represents the total weight W, in pounds, of a spa that contains g gallons of water. What is a reasonable graph of the function rule, given that the capacity of the spa is 250 gal?
Be sure to include relevant graph detail: label axes, indicate units on both axes, and use arrows to represent end behavior, as appropriate.
Use the function w(x) = 250x, which represents the average number of words a person can read in one minute to determine many words the average person can read in 6 minutes. Enter only a number.
Graph the function rule.
The amount of water w in a wading pool, in gallons, depends on the amount of time t, in minutes, the wading pool has been filling, as related by the function rule w = 3t.
Be sure to include relevant graph detail: label axes, indicate units on both axes, and use arrows to represent end behavior, as appropriate.

To solve an equation we need to undo operations to isolate a variable. So, we need to undo PEMDAS. This means we need to work in a different order.
Put these operations in the order by which you perform them to solve an equation. (first to last)
addition and subtraction (outside parentheses)
multiplication and division
parentheses ( )
Put the steps to solving this equation in the right order.
divide both sides of the equation by 3
Before we start solving, we identify the variable a, so we can solve for it the variable
add 7 to both sides of the equation
the result is x=7
Solve this equation.
What is the first step to solving this equation?
What is the second step to solving this equation?
Solve this equation.
Solve this equation.
15h - 9 = - 54
Put the steps in the correct order to solve this multistep equation.
undo multiplying by -28 by dividing by both sides of the equation by -28 to get a = 5
undo subtract 20 by adding 20 to both sides of the equations to get -28a = -140
The solution is a = 5
Use distribution to multiply (7a+5) by -4 to get -28a - 20
Check the solution by evaluating the original expression -4(7a+5) to verify that it equals -160
