If she can ride her bike 3 miles in 24 minutes how far can she ride her bike in 72minutes. So, if we find out how many times 24 goes into 72 (by dividing it) then times the answer by 3 because that’s how many miles she can do in 24 min. That will give you the answer e.g

Sally can ride her bike 4 miles in 12 minutes so how far can she ride her bike in 24 minutes. You do:

_2_. 2x 4 = 8 so she would be able to
12) 24. Do 8 miles I. 24 minutes.

What is 4(p+8) equals -4p?

kati45 [8]

4(p + 8) = -4p ... assuming you need to solve for p, the first step is to distribute the 4 to the inside of your parentheses

4p + 32 = -4p ... subtract 4p
32 = -8p ... divide by -8
p = -4 is your answer.

I need some help to tell whether a table is a linear or non linear function

Doss [256]

A linear equation has the form:

$y=mx+b$

Let's find a linear equation using the table, and let's check if it satisfy all the points:

$\begin{gathered} x=0,y=-1 \\ -1=b \\ ------ \\ x=1,y=1 \\ 1=m+b \\ 1=m-1 \\ m=2 \end{gathered}$

so:

$y=2x-1$

Let's check the other points:

$\begin{gathered} x=-3 \\ y=2(-3)-1=-6-1=-7_{\text{ }}True \\ ------ \\ x=-2 \\ y=2(-2)-1=-4-1=-5_{\text{ }}True \\ ------ \\ x=-1 \\ y=2(-1)-1=-2-1=-3_{\text{ }}True \end{gathered}$

Therefore, we can conclude it is a linear function.
