Identifying functions

Mathematics
1 answer:
Gelneren [198K]3 years ago
5 0

Answer:

If all possible vertical lines will only cross the relation in one place, then the relation is a function. This works because if a vertical line crosses a relation in more than one place it means that there must be two y values corresponding to one x value in that relation.

Answer:

A) 3 cups

B) $40.50

Step-by-step explanation:

<u>Part A</u>

Step 1 - divide the target number of pralines by the number the recipe makes:

108 ÷ 18 = 6

Step 2 - multiply this number by the amount of light cream in the recipe for one batch:

\frac{1}{2}  * 6 = 3

This means that 3 cups are needed.

<u></u>

<u>Part B</u>

Step 1 - Divide the total pralines by 4:

108 ÷ 4 = 27

Step 2 - Multiply this number by the price Kia is going to sell them:

1.50 * 27 = 40.5

So she will make $40.50 for the school.

Hope this helps!

Answer:

y = 4x + 8

Step-by-step explanation:

1) Find slope:

y2-y1/x2-x1

12-8/1-0 = 4/1 = 4

Slope = 4

2) Plug in a point in point-slope form

y-y1=m(x-x1)

y-8=4(x-0) =

y-8=4x-0 -> add 8 to both sides

y=4x+8
