Answer:

X = 4

Step-by-step explanation:

Since both 9x-6 and 30 equal f(x), we can set them equal to each other. Like this:

9x - 6 = 30

Now, just solve the equation

Add 6 to both sides

9x = 36

Then divide 9 on both sides

x = 4

Therefore, x is equal to 4.

<u>Check:</u>

9(4) - 6 = 30

36 - 6 = 30

30 = 30

mr Goodwill [35]
Y = 0 + 2

Since it is a horizontal line, the slope is m = 0.

For the y-intercept, the line passes through 2 so therefore, the y-intercept is 2 positive.

A shop keeper has 8 gallons, 3 quarts,
ioda

Answer:

I believe it would be 86 cups left of milk.

Step-by-step explanation:

8 gallons= 128 cups of milk

3 quarts= 12 cups

Plus the 1 cup of milk he had equals 141 of milk in total

Now the customer wants 2 gallons (32 cups of milk), 5 quarts ( 20 cups), and 3 cups which is 55 cups of milk.

Now we minus what the customer bought from what the shop keeper had so:

55-141=86
