Kevin bought 3 bags of gravel to cover the bottom of his fish tank. Kevin used 27 pounds of gravel to cover the bottom of the tank. How many pounds of gravel are left over?

Remain gravel = (3x - 27) pound

Step-by-step explanation:

Given:

Number of bags Kevin have = 3

Used gravel = 27 pound

Find:

Remain gravel

Assume;

Each bag carry x pound of gravel

So,

Total gravel = 3x

Remain gravel = Total gravel - Used gravel

Remain gravel = (3x - 27) pound

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
