Y = 2(x+2)^2 - 18Find the x intercepts
murzikaleks [220]

Answer

x=-5

and

x=1

Explanation

The equation y = 2(x+2)^2 - 18 corresponds to a translation 2 units left and 18 units down, and a and a shrinkage about the x-axis with factor 2.

Making these transformations to y=x^2, we have:

y=2(x+2)^2-18y=2(x{}^2+4x+4)-18y=2x^2+8x+8-18y=2x^2+8x-10

Factoring:

y=2(x^2+4x-5)y=2(x+5)(x-1)

The x-intercept are found when y=0, that is:

\begin{gathered} x+5=0 \\ x=-5 \end{gathered}

and

\begin{gathered} x-1=0 \\ x=1 \end{gathered}

Step-by-step explanation:

Let's represent Aaron's age with x and

x+x+8=44

2x+8=44

2x=44-8

2x=36

x=36÷2

x=18

Aaron is 18 years old.

While Charlene is 18+8=26 years old.

clara wants to run a total of 5 1/2 miles each lap around the track is 0.25 miles. how many laps around the track does clara nee
NemiM [27]

Answer:

22 laps

Step-by-step explanation:

Clara wants to run 5 1/2 miles, and the track is only 0.25 miles long. This is a fairly easy question, you just need to figure out how many times 5 1/2 goes into 0.25, because she wants to run that amount of miles (I could never run that much).

I hope that answers your question so you understand, and I hope you have a great rest of your day! :)
