hope it's helpful ❤❤❤
THANK YOU.
Answer:
2x² - 8
Step-by-step explanation:
Given
(x - 2)(2x + 4)
Each term in the second factor is multiplied by each term in the first factor, that is
x(2x + 4) - 2(2x + 4) ← distribute both parenthesis
= 2x² + 4x - 4x - 8 ← collect like terms
= 2x² - 8

Explain whether the graph represents a function.
Answers
Answer:
The vertical line test can be used to determine whether a graph represents a function. ... If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output. A function has only one output value for each input value.
how many solutions does x=-2 have
Answers
Answer:
One solution
Step-by-step explanation:
In a one- variable equation has infinitely many solutions when solving results in a true statement, such as 2=2
In a one- variable equation has one solution when solving results in one value for the variable, such as x = 5
In a one - variable equation has no solution when solving results in an untrue statement, such as 2=3
So, in this case the result x = -2 belongs to the 2nd sentence where it says one solution.

If 2^2x = 2^3, what is the value of x?
Answers
Answer:
X = 3/2.
Step-by-step explanation:
Please refer to the attachment given above.
The value of x in the equation 2[tex]^{(2x)}[/tex] = 2³ is 1.5.
To find the value of x in the equation 2[tex]^{(2x)}[/tex] = 2³, we can use the property of exponents that states: If two exponential expressions have the same base and are equal, then their exponents must be equal.
In this case, we have 2[tex]^{(2x)}[/tex] = 2³. Since the bases are the same (both are 2), we can equate the exponents:
2x = 3
Now, to solve for x, divide both sides by 2:
x = 3/2
So, the value of x is 3/2 or 1.5.

PLEASE HELP ITS MATH!!!!
This triangle has one side that lies on an extended line segment. Based on this triangle, what statement about x is true? A. x = 27 because 180−109−44=27 B. x = 65 because 109−44=65 and 44 + 65 = 109 C. x = 71 because 180−109=71 D. x = 153 because 109 + 44 = 153 and 153−44=109
MEASUREMENTS (down below)
A triangle with base on an extended line. Two angle measures are given. Top interior angle is forty-four degrees. Lower right exterior angle is one hundred nine degrees. Lower left interior angle is labeled x degrees.
Answers
Answer:
B. x = 65 because 109−44=65 and 44 + 65 = 109
Step-by-step explanation:
Given :
The triangle below :
Sum of interior angles of a triangle :
(44° + x + (180 - 109) = 180°
44° + x + 71° = 180
115° + x = 180°
x = 180° - 115°
x = 65°
a) Show that the equation x^3 + 6x - 5 = 0 has a solution between x = 0 and x = 1
Answers
Answer:
Since [tex]f(0) < f(x) < f(1)[/tex], there is a solution for [tex]f(x)[/tex] between [tex]x = 0[/tex] and [tex]x = 1[/tex].
Step-by-step explanation:
A solution of the polynomial is a root such that sign of dependent value changes, either from positive to negative or from negative to positive. Let [tex]f(x) = x^{3} + 6\cdot x - 5[/tex], [tex]x[/tex] is a solution of the equation if and only if [tex]f(x) = 0[/tex]. We proceed to evaluate the function at each bound:
x = 0
[tex]f(0) = 0^{3}+6\cdot (0) - 5[/tex]
[tex]f(0) = -5[/tex]
x = 1
[tex]f(1) = 1^{3}+6\cdot (1) - 5[/tex]
[tex]f(1) = 2[/tex]
Since [tex]f(0) < f(x) < f(1)[/tex], there is a solution for [tex]f(x)[/tex] between [tex]x = 0[/tex] and [tex]x = 1[/tex].

It takes 3 1/2 spoons of chocolate syrup to make 3 2/5 gallons of chocolate milk. How many spoons would it take to make 4 gallons of chocolate milk?
Answers
Answer:
4 2/17
Step-by-step explanation:
It takes 3 1/2 spoons of chocolate syrup to make 3 2/5 gallons of chocolate milk
3 1/2= 3 2/5
7/2= 17/5
1 gallon = 7/2÷17/5
= 7/2 × 5/17
= 35/34
Therefore the number of spoons required to make 4 gallons
= 4 × 35/34
= 140/34
= 70/17
= 4 2/17

Which statement is true? (1 point)
Answers
Answer:
You didnt show the statements...
Step-by-step explanation:
(02.02 MC) Triangle ABC is shown. A is at negative 2, 1. B is at negative 1, 4. C is at negative 4, 5. If triangle ABC is reflected over the x‐axis, reflected over the y‐axis, and rotated 180 degrees, where will point B' lie? (−1, 4) (1, −4) (4, −1) (−4, 1)
Answers
Answer:
(-1,4)
Step-by-step explanation:
Point B in the pre-image is at (-1,4).
If triangle ABC is reflected over the x‐axis, the y-coordinate changes to its negative value, thus we have the transformation:
Next, if the point (-1,-4) is reflected over the y‐axis, the x-coordinate changes to its negative, Thus, we have the transformation:
Finally, a rotation by 180 degrees will give the coordinates of B' as:
The point B' will lie in (-1, 4) [ the same place as B].
The coordinates of point B' are [tex](-1,4)[/tex]. So, the first option is correct.
Given:
The vertices of a triangle ABC are [tex]A(-2,1), B(-1,4)[/tex] and [tex]C(-4,5)[/tex].
Triangle ABC is reflected over the x‐axis, reflected over the y‐axis, and rotated 180 degrees.
To find:
The point B'.
Solution:
If a figure reflected over x-axis, then
[tex](x,y)\to (x,-y)[/tex]
[tex]B(-1,4)\to B_1(-1,-4)[/tex]
If a figure reflected over y-axis, then
[tex](x,y)\to (-x,y)[/tex]
[tex]B_1(-1,-4)\to B_2(-(-1),-4)[/tex]
[tex]B_1(-1,-4)\to B_2(1,-4)[/tex]
If a figure rotated 180 degrees about the origin, then
[tex](x,y)\to (-x,-y)[/tex]
[tex]B_2(1,-4)\to B'(-(1),-(-4))[/tex]
[tex]B_2(1,-4)\to B'(-1,4)[/tex]
So, the coordinates of point B' are [tex](-1,4)[/tex].
Therefore, the first option is correct.
