Answer:
Step-by-step explanation:
Given the x-intercepts at -1 and 5, that means y=0 at x=-1 and x=5.
So (x+1) and (x-5) are root for the parabola.
y = (x+1)*(x-5)
That is the quadratic equation for Question B.
Back to A, the x-coordinate of vertex of this parabola is at x=2.
This is because the parabola is symmetrical at its vertex so the vertex must be at the mid-point between its x-intercepts, x=(-1+5)/2=2.

Simplify 4x + 8 + 2x - 7

6x+1
Step-by-step explanation:
Answer:
6x+1
Step-by-step explanation:
Hi there!
We are given the following expression:
4x + 8 + 2x - 7
And we want to simplify
When we simplify, we want to combine like terms. This means that we want to add terms with the same variables together (like x), and then combine them
If there is no variable, then we add and combine the terms that don't have any variable together as well
Please note that we cannot combine terms with different variables (so if you had x+y, then it would stay as x+y).
In this case, we have 4x + 8 + 2x - 7
4x and 2x are like terms; they have the same variable (x). If we add them together, the result is 6x
8 and -7 are also like terms; they both don't have a variable. If we add (or rather, subtract) these terms, the result is 1.
Now we add 6x and 1 together, which would be 6x+1 (1 doesn't have a variable after it, so we can't combine it with 6x).
6x+1 is our answer.
Hope this helps!

The simplified form of the expression is 8.3y + 3.1
Equations and expressionsGiven the following equations
(8-0.2+0.5)y + (2.2+1.3 - 0.4)
First is to Reorder the expression to have:
(8+0.5-0.2)y + (2.2+1.3 - 0.4)
Group the resulting expression
[8.5-0.2]y + (3.5 - 0.4)

The vertex of a quadratic equation is given at (−2, 1), and the quadratic is concave up. How can the range and domain be described?
Question options:
Domain: [1, ∞)
Range: (−∞, ∞)
Domain: (−∞, ∞)
Range: [1, ∞)
Domain: [−2, ∞)
Range: (−∞, ∞)
Domain: (−∞, ∞)
Range: [−2, ∞)
Answers
First answer
Explanation:
Just as a reminder, domain is the x values that would give a defined answer for y, and range is the possible values y could get.
The domain of every polynomial is (-infinity, infinity), because there isn’t any value that could make it undefined.
Since this is an upward opening parabola, it’s vertex is its minimum point, which is 1. That means the range would be [1, infinity).
This means the answer is:
Domain: [1, infinity)
Range: ( -infinity, infinity)

Which two are correct? Please help me out with this
Answers
Answer:
I think
Step-by-step explanation:
D and E are right.
==================================================
Explanation:
The domain is the set of all real numbers because we can replace x with any real number we want to get some y output. There isn't any restriction on x. We don't have to worry about dividing by zero for instance. This is why choice A is one of the answers.
The range is restricted however. The largest value we can make in the range is y = 0. The graph of y = -4x^2 shows a parabola that opens upside down. The highest point is at (0,0). So that's why choice D is the other answer.
---------------------------
Extra info:
Choice B is false because we can get outputs like y = -3, y = -2, y = -1, or y = 0.Choice C is false. A parabola has one half increasing, and the other half decreasing.Choice E is false since there is only one x intercept and it happens at (0,0) in this case. This is also the location of the y intercept as well.

To find the answer we substitute the values of each option in till we find the answer that doesn't equal 36 square units, since the question already gives us the area of the rectangle.
Option A:
[tex]A=w\times h[/tex]
[tex]A=4\times8[/tex]
