Answer:

Step-by-step explanation:

First, we plug in -3 in place of x...

f(x) = 2(-3)^2 + (-3) + 1

Then, we simplify each indidvidual expression...

f(x) = 18 - 3 + 1

Finally, we add/subtract all the values to get our answer...

f(x) = 16

Korvikt [17]

Answer:

The rate at which water leaking is $\frac{1}{8}$ gal/min.

Step-by-step explanation:

Given:

A large container holds 8 gallons of water.

After 56 minutes the container only has 1 gallon of water left.

Now, to find at what rate is the water leaking.

So, water leaked from the container = 8 gallons - 1 gallon = 7 gallons.

Time taken for leakage = 56 minutes.

$\frac{Gallons\ of\ water\ leaked}{Time\ taken\ for\ leakage}$

$=\frac{7 gallons}{56 minutes}$

$=\frac{1 gallon}{8 minutes}$

The rate = $\frac{1}{8}$ gal/min.

Therefore, the rate at which water is leaking is $\frac{1}{8}$ gal/min.

Answer:

( x + 2 ) and ( x - 11 )

Step-by-step explanation:

x² - 9x - 22 = 0

x² + 2x - 11x - 22 = 0

x ( x + 2 ) - 11 ( x + 2 ) = 0

( x + 2 ) ( x - 11 ) = 0

Factors of x² - 9x - 22 are ( x + 2 ) and ( x - 11 ).
