Answer:

  1)  D. distributive property

  2)  C. D=all real numbers; R = {y | y ≥ 0}

Step-by-step explanation:

1) We observe that the factor of -4 has been multiplied by each of the terms of the binomial in parentheses. This is an application of the distributive property.

__

2) Any polynomial has a domain of all real numbers. The range of an even-degree polynomial will be limited by its extreme value. Here, the vertex of this quadratic function is (1, 0), so the range is all non-negative real numbers.

  F(x) = x^2 -2x +1 = (x -1)^2

Any square will have a minimum value of 0. For this function, that occurs at ...

  (x, y) = (1, 0)

The range will be values of y equal to or greater than zero.

QUESTION POSTED AT 28/03/2020 - 11:14 AM

1. Solve each equation, if possible. Write irrational numbers in simplest radical form. Describe the strategy you used to get your solution and tell why you chose that strategy. x^2+4=0 x^2-6x+1=0

X^2 + 4 = 0
Using the square root method, subtract 4 from both sides.
x^2 = -4
To clear the power of 2, take the square root of both sides.
x = + - square rot of (-4)
x = + - 2i
This is a complex answer because the radicand was a negative number.

x^2 - 6x + 1 = 0
I would use completing the square to solve this problem.
Subtract 1 from both sides.
x^2 - 6x = -1
When completing the square, take the b term (-6) and divide by 2 (-6/2= -3),
then square this number (9), add the number to both sides.
x^2 - 6x + 9 = -1 + 9
The left side is now a perfect square trinomial.
(x - 3)^2 = 8
To clear the power of 2, take the square root of both sides.
x - 3 = + - sqrt 8
add 3 to both sides and simplify sqrt 8
x = 3 + - 2sqrt2

What is the value of X if 3/2x +4 =2x-1

Let's isolate x by moving the -1 to the left and the 3/2x to the right (direction chosen so that you don't get negative numbers):

4 + 1 = 2x - \frac{3}{2}x \implies 5 = \frac{1}{2}x

Now multiply both sides by 2 and swap sides:

2 \cdot 5 = 2 \cdot \frac{1}{2}x \implies x = 10

Solve equation for 5x-14=8x+4

Remember, you can do anything to an equation as long as you do it to both sides


get 1 of the x on one side

5x-14=8x+4
minus 5x both sides (we want on left side because 8>5 and I like positive stuff)

5x-5x-14=8x-5x+4
0-14=3x+4
-14=3x+4
minus 4 both sides
-14-4=3x+4-4
-18=3x+0
-18=3x
divide both sides by 3
remember, negative/positive=negative
-18/3=(3x)/3
-6=x(3/3)

WILL GIVE A BRAINLIEST!! The graph of a quadratic function is a parabola that opens down and has a vertex of (4, 3). Which of the following could be the function? A. y=-x^2+4x+3 B. y=-x^2+8x-13 C. y=x^2-4x+3 D. y=x^2-8x-13

Answer:

B.

 y=-x^{2} +8x-13

Step-by-step explanation:

We know that the vertex of the parabola is

V(4,3)

That means this points is being intercept by the parabola. In other words, the function that represents this parabola has to have this relation, when x=4, y=3.

So, you can observe that the second choice has a function that follows this relation. Let's see

y=-x^{2} +8x-13

So, for x=4

y=-(4)^{2} +8(4)-13\\y=-16+32-13\\y=3

Therefore, function B is the answer because it includes the vertex at its relation.

4) C: These triangles are reflection of each other, if you would place them in front of a mirror, this would be the only one true.

5) A: According to the picture, the angles are the same, so what will be missing is to know if the hypotenuse is the same, as we already know that one side is the same (perpendicular one), therefore we already have S(side), A (angle), missing side (S) for it to be solved by SAS.

6) A: ASA postulate says that you need one angle (A1), the side between A1 and A2, and a second angle (A2), which corresponds to tha description.

7) missing the picture

8) B: 65. Two of the angles are 90 and the other one is 125. Within any quadrilateral the sum of angles must be 360. Therefore m=360-90-90-125=65.

[x(x-3)]/[x⁻¹(x+4)]
Simplifying further we have:

Solving for restriction we equate the denominator to 0:
