Answer:
Choice B: 
.
Step-by-step explanation:
For a parabola with vertex 
, the vertex form equation of that parabola in would be:
.
In this question, the vertex is 
, such that 
and 
. There would exist a constant 
such that the equation of this parabola would be:
.
The next step is to find the value of the constant .
Given that this parabola includes the point 
, 
and 
would need to satisfy the equation of this parabola, .
Substitute these two values into the equation for this parabola:
.
Solve this equation for :
.
.
Hence, the equation of this parabola would be:
.
Answer:
A
Step-by-step explanation:
f(x) = 2x^2 – 3x + 1 is a function (its graph is a parabola that opens up), and it is one-to-one (Answer A). For each input, x, this function will return one output.
I’m guessing you mean like this.
2x+4y+5x+8y.
2x and 5x are like terms because the x’s are alike. If you add 2+5, the answer is 7. So therefore 2x+5x=7x.
4y and 8y are like terms because the y’s are alike. So the answer to 4y+8y would be 12y.
If you need extra help, give me a problem and I will help you solve it.

Step-by-step explanation:
4(y+7)=4(y)+4(7)
=4y+28
Answer:
Volume = 308
Step-by-step explanation:
Volume of a rectangular prism = Height * Width * Depth
Sub in the three values and solve
V = 11 * 7 * 4
V = 308
