The long jump pit at Martha's middle school is 9 1/3 feet long. Martha used rope to mark off a practice pit in her backyard, but she only had space to make one that was 3/4 as long. How long was Martha's practice pit?

Martha's pit was 7 feet long.

Step-by-step explanation:

Given:

The long jump pit at Martha's middle school is 9 1/3 feet long.

Martha used rope to mark off a practice pit in her backyard, but she only had space to make one that was 3/4 as long.

Now, to find the length of Martha's practice pit.

The length of Martha's school pit =

And the length of practice pit of Martha is =

Now, to get the length of Martha's practice pit:

=

Therefore, Martha's pit was 7 feet long.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
