Answer:

A, C, F

Step-by-step explanation:

<h3><u>Given</u>:</h3>

A : 4xy- 6x = y + 5

B: y^2-5x = 6

C: y^3 = 6-3x

D: y^2 + 2y =-x

E: |x+y| = 7

F: 5x - 6y + 3 = 0

G: |y| = 2x - 5

H: y^l0-8x- 1

Which equations graph as a function of x.

<h3><u>Solution</u>:</h3>

Even-degree polynomial terms in y, and absolute-value expressions involving y can result in a given x-value being mapped to multiple y-values. When that is the case, the relation is not a function.

The relations that are functions of x are ...

A, C, F

The others are not, because ...

even-degree in y: B, D, H
absolute value in y: E, G

slamgirl [31]

Answer:

32 cups

Step-by-step explanation:

To find the total number of cups, we have to convert the measures that are not in cups to cups and add

1 quart = 4 cups

4 quarts = 4 x4 = 16 cups

1 pint = 2 cups

6 pints = 2 x 6 = 12 pints

total number of cups = 16 + 12 + 4 = 32 cups
