Points B, C, G, and H represent the equation.
I would have figured this out by graphing the line.
y= -2x + 5
2x represents the slope and 5 represents where the line crosses the y-axis, aka the y-intercept.
So you can start at point (0,5) and then go down 2, right 1 (-2/1 = -2), connect those points to make a line and then see which points are on the line.

You could have also plugged each point's x-coordinate into the equation and see if the answer results in its y-coordinate or not.

The mean of a set of data is 45 years. Find the missing numbers in the data set {40, 45, 48, ?, 54, ?, 45}. Explain the method or strategy you used.

Answers

There are 7 numbers. 7 X 45 equals 315. 40+45+48+54+45=232.
315-232=83.

The 2 numbers can each have different values, such as 41 and 42, or 40 and 43. The numbers must add up to 83, though.

The function f(x)=x^2 -6x+3 is transformed such that g(x)=f(x-2). Find the vertex of g(x). (5,6)

(5,-8)

(1,-6)

(3,-8)

Answers

Answer:

$g(x) = (x-2)^2 -6(x-2) +3$

$g(x) = x^2 -4x +4 -6x +12 +3$

$g(x) = x^2 -10 x +19$

$g(x) = x^2 -10 x + 25 +19 -25$

$g(x) = (x-5)^2 -6$

$y= (x-h)^2 -kk$

Where h,k represent the vertex and we got:

$(h,k)= (5,6)$

(5,6)

Step-by-step explanation:

We have this original function given :

$f(x) = x^2 -6x +3$

And we want to find the vertex for this new function $g(x) = f(x-2)$ and we have:

$g(x) = (x-2)^2 -6(x-2) +3$

And solving the square we got:

$g(x) = x^2 -4x +4 -6x +12 +3$

And adding similar terms we got:

$g(x) = x^2 -10 x +19$

Now we can complete the square like this:

$g(x) = x^2 -10 x + 25 +19 -25$

$g(x) = (x-5)^2 -6$

The general equation is given by:

$y= (x-h)^2 -kk$

Where h,k represent the vertex and we got:

$(h,k)= (5,6)$

I got 50 but that's the wrong answer when I put it in

Answers

Answer:

the answer is 50

Step-by-step explanation:

first you want to get the 54 off so you subtract it form both sides and get 1v=50 and then you want to get 1 off so you dived and get v=50. thats strange
