Answer and Step-by-step explanation:

The answer is the last answer choice.

g(x) = -(x + 2)^2 + 1

We don't even have to look at the numbers to tell that this is the correct answer. We look at what is being placed there.

The equation for a transformed function is:

f(x) = a(x-h)^2 + k

a determines the scale of the graph and whether the graph opens up or down.

h determines whether the graph shifts left or right.

k determines whether the graph shifts up or down.

We see that there is a -1 for a, which means the graph will be facing downwards. We see a 2 for where h is, but it really is a -2, and when it becomes a positive after simplifying, the graph will shift to the left.

k is a positive 1, so the graph will be shifted up 1 unit.

<u>Thus, the answer is the last answer choice.</u>

Alicia drives her car 287.5 miles in 5 hours. What is the constant of proportionality that relates the total number of miles, y,
Sphinxa [80]

Answer:

  57.5

Step-by-step explanation:

The constant of proportionality is "k" in the equation ...

  y = kx

It can be found from values of x and y using ...

  k = y/x

For the given values, it is ...

  k = (287.5 mi)/(5 h) = 57.5 mi/h

The constant of proportionality relating miles to hours is 57.5.

The quadratic x^2+7x+20$ has the same roots as the quadratic Ax^2+Bx+1 What is A+B?
sdas [7]

If f(x)=x^2+7x+20 has the same roots as g(x)=Ax^2+Bx+1, then

one must be a multiple of the other.


By comparison of the constant terms, we know that 20g(x)=f(x), or

g(x)=(1/20)f(x)

=(1/20)(x^2+7x+20)

=(1/20)x^2 + (7/20)x + 20/20

=(1/20)x^2 + (7/20)x + 1


Therefore A=(1/20), B=(7/20),  and A+B=(1+7)/20=8/20=2/5
