Step-by-step explanation:
The polynomial function B(x) = -21x + 20 with a factor of (x - 4) is
- 21x² + 104x - 80.
What is a factor of a polynomial?We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.
To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.
Given, the polynomial function
B (x) = - 21x + 20 has a known factor of (x - 4).
This as a product of two factors can be written as,
(- 21x + 20)(x - 4).
= - 21x² + 84x + 20x - 80.
= - 21x² + 104x - 80.

Start with the top figure. Which transformation was used to create the pattern?
The transformation that was used to create the pattern is rotation. The correct option is A, rotation.
What is the transformation in logic?If two formulae are logically identical, either one may replace the other in any well-formed context without changing anything's truth value or inferential qualities. This is a fundamental property of logic.
The given figure in the top is needed to be transformed such that the pattern given below is produced. Therefore, if we observe the figure at the top and the pattern, then it can be seen that the given figure is rotated by 90° to create the given pattern. The pattern will be formed.
Hence, the transformation that was used to create the pattern is rotation.

*NEED HELP ASAP
Answer:
The correct option is;
a- 45° only
Step-by-step explanation:
The given equation can be presented as follows;
[tex]\dfrac{cos (2 \cdot x)}{cosine (x) + sin (x)} = 0[/tex]
We have that cos(2·x) = cos²(x) - sin²(x)
Also, we have, by the difference of two squares, the following relation;
cos²(x) - sin²(x) = (cos(x) - sin(x))(cos(x) + sin(x))
Therefore, the given equation can be written as follows;
[tex]\dfrac{cos (2 \cdot x)}{cosine (x) + sin (x)} = \dfrac{(cos(x) - sin(x)) \times (cos(x) + sin(x))}{(cos (x) + sin (x))} =0[/tex]
Crossing the common term, (cos(x) + sin(x)), in the numerator and the denominator, we have;
[tex]\dfrac{(cos(x) - sin(x)) \times (cos(x) + sin(x))}{(cos (x) + sin (x))} = cos(x) - sin(x) = 0[/tex]
From cos(x) - sin(x) = 0, we have;
Adding sin(x) to both sides of the equation
cos(x) - sin(x) + sin(x) = 0 + sin(x)
cos(x) = sin(x)
Therefore, the opposite leg and the adjacent leg of the right triangle formed with reference to the angle x are equal

Answer:
z=97 x=21
Step-by-step explanation:
so straight angles always equal 180°
And assuming that your lines are parallel, the angle under angle z should be 83° just like the angle above angle z
There for to solve for x, first subtract 83 from 180 because that's what that angle is equal to.
Now that you have the equation 4x+13 and you know that it's equal to 97 you can solve it just like a normal inequality.
4x+13=97
4x=84
x=21

Convert the equation from standard form to slope-intercept form.
Answer:
y=x-1
Step-by-step explanation:
The equation is currently in standard form which is a+b=y and slope-intercept is y=mx+b where m is the slope and b is the y-intercept. To change the form we must move the terms around using Properties of Equality.
First, subtract 1 from both sides
x-y-1=1-1
x-y-1=0
Then, add y to both sides
x-y-1+y=0+y
x-1=y
So that is the equation in slope-intercept form with a slope of 1 and a y-intercept of -1.
Answer:
y=x-1
Step-by-step explanation:
It is y=x-1 because first when we do ANYTHING first. We leave the y on the left side of the equation, since the slope y=mx+b has the y always on the left side. So we subtract x from both sides and we get -y=-x+1. We are NOT DONE yet, so after this, we divide both sides by -1. Why? This is because you cannot have a negative y. Dividing both sides by -1 you finally get y=x-1. If this is trouble some to read, I will also put how to solve the problem down below. :)
Let's solve for y.
x−y=1
Step 1: Add -x to both sides.
x−y=1+−x
−x
−y=−x+1
Step 2: Divide both sides by -1.
−y/ −1 = −x+1 /−1
y=x−1
Answer:
y=x−1

What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 6 is an equation.
We have,
y = 2x + 2
y = x - 2
Now,
The point of intersection.
2x + 2 = x - 2
2x - x = -2 - 2
x = -4
Putting in y = 2x + 2
y = 2 x -4 + 2
y = -8 + 2
y = -6
(-4, -6) is the point of intersection.
Now,
The graph of the equation is given below.
Thus,
The point of intersection between the two equations is (-4, -6).

11. A. y = 24x
12. C. c = 0.5p
13. D. p = (1/200)n
14. C. 5 : 8
Step-by-step explanation:
11. y = 24x is correct because you multiply the number of days (x) by 24 to get the number of hours (y)
12. c = 0.5p is correct because there are half as many c as p. so to get c, you multiply p x 1/2.
13. If we substitute in, p is 1/4. 1/200 times n = 0.25 or 1/4. So D. is correct.
14. The ratio of apples to oranges is 15 : 24. We can divide 15 and 24 both by 3 to get 5 : 8.
