Assoli18 [71]

Answer: See explanation

Step-by-step explanation:

You didn't state the sentences but let me help out based on the information given.

Number of new motion toys = 12

Number of batteries used by each toy = 3

Since N represents the total number of batteries he need, the value of N will be:

= Number of toys × Number of batteries used by each toy

= 12 × 3

= 36

That means N equals 36.

What is the slope between the points (5,-4) and (-3,4) <br> -1<br> 4<br> 0<br> 1
kumpel [21]

Answer:

The answer is -1.

Step-by-step explanation:

You have to apply gradient formula :

m =  \frac{y2 - y1}{x2 - x1}

So you will have to substitute the coordinates into the equation. Let (x1,y1) be (-3,4) and (x2,y2) be (5,-4) :

m =  \frac{ - 4 - 4}{5 - ( - 3)}

m =  \frac{ - 8}{8}

m =  - 1
