Step-by-step explanation:

x {}^{2}  + 3x - 18 \\  = x {}^{2}  + (6 - 3)x - 18 \\  = x {}^{2}  + 6x - 3x - 18 \\  = x(x + 6) - 3(x + 6) \\  = (x + 6)(x - 3)

It takes Hayden 1 1/2 minutes t complete each level of his video game. If he plays for 10 1/4 minutes, how many levels will he c
antoniya [11.8K]

Given:

Hayden 1\dfrac{1}{2} minutes to complete each level of his video game.

He plays for 10\dfrac{1}{4} minutes.

To find:

The number of levels he will complete.

Solution:

We have,

Required time for each level = 1\dfrac{1}{2}

Total time = 10\dfrac{1}{4}

The number of level is

n=\dfrac{\text{Total time}}{\text{Required time for each level}}

n=\dfrac{10\dfrac{1}{4}}{1\dfrac{1}{2}}

n=\dfrac{\dfrac{10(4)+1}{4}}{\dfrac{1(2)+1}{2}}

n=\dfrac{\dfrac{41}{4}}{\dfrac{3}{2}}

On further simplification, we get

n=\dfrac{41}{4}\times \dfrac{2}{3}

n=\dfrac{41}{6}

n=6.8333...

Number of levels must be a whole number. So, approx to value to the preceding whole number.

n\approx 6

Therefore, Hayden will complete 6 levels if he plays for 10\dfrac{1}{4} minutes.

Answer:

y= (x - 12)^3

y= (x - 4)^3

Step-by-step explanation:

Shift to the right is a horizontal shift so it needs to be with x in the parenthesis. And negative because it is to the right.

y= (x - 12)^3

y= (x - 4)^3

are the two that fit those criteria
