Answer:
d*y
Step-by-step explanation:
You have to change the fractions into improper fractions and then change the denominators so they are equal
F ( x ) = √( 12 x + 24)
12 x + 24 ≥ 0
12 x ≥ - 24
x ≥ - 24 : 12
x ≥ - 2
Answer:
The domain of the function is:
x ∈ [ - 2, + ∞ )
Answer:

Step-by-step explanation:
Let
d ----> distance Tess runs in miles
p ---> the number of track practices she attends
we have

This is a linear equation in slope intercept form
where
The slope or unit rate is

The y-intercept (value of d when the value of p is equal to zero) is

so
For d=11 miles
substitute in the linear equation and solve for p

solve for p

.1125 = 11.25% or 11 1/4(fraction)
