Answer: Choice D
(2,2) is the solution to line A, but not to line B
==========================================================
Explanation:
Let's find the equation of line A
First we need the slope
m = (y2-y1)/(x2-x1)
m = (6-0)/(0-3)
m = 6/(-3)
m = -2
Since the point (0,6) is on line A, we know b = 6 is the y intercept.
The equation of line A is y = -2x+6.
-----------------------------
Let's find the equation for line B
So we need the slope
m = (y2-y1)/(x2-x1)
m = (5-0)/(5-0)
m = 5/5
m = 1
The y intercept is b = 0 since the line goes through (0,0)
The equation of line B is y = 5x+0 which is the same as y = 5x.
------------------------------
Our system of equations is
[tex]\begin{cases}y = -2x+6\\y = 5x\end{cases}[/tex]
We can see that plugging x = 0 into line A's equation leads to y = 6. So (0,6) is on line A. However, the point (0,6) is not on line B because plugging x = 0 leads to y = 0.
This allows us to rule out choices A and B.
--------------------------------
Let's see what happens when we plug in x = 2 to line A
y = -2x+6
y = -2*2+6
y = -4+6
y = 2
The point (2,2) is on line A
Now let's do the same for line B
y = 5x
y = 5*2
y = 10
The point (2,10) is on line B meaning that (2,2) is not on line B.
We can rule out choice C and conclude that choice D is the final answer.
Side note: Choice D should read "(2,2) is a solution" instead of "(2,2) is the solution" since there are infinitely many solutions on any given line. So another solution for example would be (0,6).

One solution to a quadratic equation is x = 1 + 8i. What is the other solution?
We'll assume the quadratic equation has real coefficients
Answer:
The other solution is x=1-8i.
Step-by-step explanation:
The Complex Conjugate Root Theorem
if P(x) is a polynomial in x with real coefficients, and a + bi is a root of P(x) with a and b real numbers, then its complex conjugate a − bi is also a root of P(x).
The question does not specify if the quadratic equation has real coefficients, but we will assume that.
Given x=1+8i is one solution of the equation, the complex conjugate root theorem guarantees that the other solution must be x=1-8i.
Answer:
the answer would be x= 1-8i

What is the value of n?
What is the value of n?
Answer:
42
Step-by-step explanation:
You get 42 by looking at the denominators 7 and 21. You times by 3 to get from 7 to 21, so you times 14 by 3 to get n, which is 42.
Answer:
42
Step-by-step explanation:
On the bottom 7 was multiplied by 3 so you would do the same to 14.
What is y=3x+13 in standard form?
Answer:
3 x − y = − 13
Step-by-step explanation:
Any equation that relates the first power of x to the first power of y produces a straight line on an x-y graph. The standard form of such an equation is Ax + By + C = 0 or Ax + By = C. When you rearrange this equation to get y by itself on the left side, it takes the form y = mx +b. This is called slope intercept form because m is equal to the slope of the line, and b is the value of y when x = 0, which makes it the y-intercept. Converting from slope intercept form to standard form takes little more than basic arithmetic.
TLDR:
To convert from slope intercept form y = mx + b to standard form Ax + By + C = 0, let m = A/B, collect all terms on the left side of the equation and multiply by the denominator B to get rid of the fraction.
Answer:
3x - y = -13
Step-by-step explanation:
y = mx + b
(This is the slope intercept form)
We want to change it to standard form, which is:
Ax + By = C
We want to rearrange as many of the numbers as we can, without actually changing the problem!
Ax = 3x
By = y
C = 13
So we must move the numbers from one side to another.
Whatever you do to one side, you do to the other.
y = 3x + 13
-3x + y = -3x - y
--------------------
-3x + y = 13
Since we can't have our "Ax" as a negative multiply everything by -1
-1[-3x + y = 13]
3x - y = -13
That is your answer.

The alternate angles theorem states that if two parallel lines are cut by a transversal, then each pair of alternate interior angles are equal.
21y - 1 = 4x + 23
21y - 24 = 4x
5.25y - 6 = x
21y - 1 = 4x + 23
21y = 4x + 24
y = 4/21(5.25 - 6) + 1.14
y = 1 - 1.14 + 1.14
y = 1
5.25(1) - 6 = x
-0.75 = x

Problem 10
Answer: 80 degreesWork Shown: 80-0 = 80
You subtract the values on the protractor where the two angle arms line up.
============================================
Problem 11
Answer: 45 degreesWork Shown: 45-0 = 45
Same idea as problem 10
============================================
Problem 12
Answer: 83 degreesWork Shown: 128-45 = 83
Same idea as the others. The arm TS isn't fully on 130 degrees, and it's a bit short of it. It looks to be about 128 degrees or so.
============================================
Problem 13
Answer: 35 degreesExplanation: Luis forgot to subtract the value of each arm of the angle. So he should have done 80-45 = 35. The answer would be 80 degrees if arm TQ was at 0 degrees (so 80-0 = 80), but instead TQ is at 45 degrees.
Identify the slope and y-intercept from the following equation.
Answer:
The slope is 2/5 and the y intercept is -4
Step-by-step explanation:
The slope is always the coefficient to x
Answer:
slope = [tex]\frac{2}{5}[/tex] , y- intercept = - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{2}{5}[/tex] x - 4 ← is in slope- intercept form
with slope m = [tex]\frac{2}{5}[/tex] and y- intercept c = - 4

The function
has the same amplitude as the function y = cos(x – 4) + 1.
The function
is a translation of the parent cosine function.

Step-by-step explanation: just took it
Function [tex]y=cos2(x)-2[/tex] and function [tex]y=cos(x)-3[/tex].
Function:A function in mathematics from a set [tex]x[/tex] to a set [tex]y[/tex] allocates exactly one element [tex]y[/tex] to each element [tex]x[/tex]. The sets [tex]x[/tex] and [tex]y[/tex] are collectively referred to as the function's domain and codomain, respectively.Initially, functions represented the idealized relationship between two changing quantities. A planet's position, for instance, depends on time. In the past, the idea was developed with the infinitesimal calculus at the end of the 17th century, and the functions that were taken into consideration until the 19th century were differentiable (that is, they had a high degree of regularity).Solution -
The function which has the same amplitude as the function [tex]y=cos(x-4)+1[/tex] and is the translation of the parent cosine is as follows:
[tex]y=cos2(x)-2[/tex][tex]y=cos(x)-3[/tex]Therefore, function [tex]y=cos2(x)-2[/tex] , and function [tex]y=cos(x)-3[/tex].
