Answer:
{-3,-1, 4, 5, 9, 10, 11, 13}
Step-by-step explanation:
B: (10 - 5i) + (5 - 10i) = (5 - 10i) +(10 – 5i)
C: (5+ 10i)+(- 5 - 10i) = 0+ Oi
D: [(0 - 5i)+(5-i)] +(5 +i) = (0 - 5i)+[(5 - i) +(5+i)]
1b) Which of the following demonstrates the commutative property of multiplication?
A: (8+6i)(4+2i)=(4+2i)(8+6i)
B: (7-6i)(0+2i)=(7+2i)(0-6i)
C: (2+8i)(2-8i)=20
D: (-5+3i)(-1+i)=(5-3i)(1+i)
Answer:
The answer to 1a is B and the answer to 1b) is A.
Step-by-step explanation:
I got my answer right on the quiz. So, it's actually a lot easier than it seems. Imagine 4+2=2+4 or (8)(4)=(4)(8). That is commutative property of addition and multiplication just simper. In this case B and A are the same thing just with complex numbers.

Answer:
x=6
Step-by-step explanation:
3x=14+4
x=18/3
i.e x = 6
Answer: x=4
Step-by-step explanation:
tangent lines from the same point to a circle are congruent in length, so we can say that
5x+8 = 8x-4
5x -5x +8 = 8x - 5x -4
8 = 3x - 4
8+4 = 3x -4 + 4
3x = 12
3x/3 = 12/3
x=4
Tangent Meaning in Trigonometry
In trigonometry, the tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side. In other words, it is the ratio of sine and cosine function of an acute angle such that the value of cosine function should not equal zero.

Answer:
x=4
Step-by-step explanation:
tangent lines from the same point to a circle are congruent in length, so we can say that
5x+8 = 8x-4
5x -5x +8 = 8x - 5x -4
8 = 3x - 4
8+4 = 3x -4 + 4
3x = 12

Answer:
refer attachment for the graph.
Step-by-step explanation:
Given: The equation
We have to draw the the graph for the given equation.
Consider the given equation
The vertex of the parabola of the form is given by
Here, a = 1 , b = -5 and c = 4
Thus, vertex is
Also, the y coordinate at is
Simplify, we get,
Thus, The vertex of parabola is
y - intercept is the point where x = 0
Plug x = 0 in given equation
Thus, y - intercept is (0,4)
Now, we calculate x- intercept
x- intercept is where y is equal to 0.
Put f(x) = 0
We have,
Solving the given quadratic equation using quadratic formula ,we have
we have a = 1 , b = -5 and c = 4
Simplify, we have,
Thus,
Thus, The x - intercept are (4,0) and (0,1)
Plot the graph and we obtain as shown below.
Answer:
A. Only graph B and D
Step-by-step explanation:
Hi, to answer this question we have to analyze the options given:
A function has only one output value (y) for each input value.(x)
In other words, If we draw a vertical line (anywhere on the graph) that intersects the graph in two points or more, then the graph does not represent a function because that x value has more than one output(y).
So, the correct option is:
A. Only graph B and D
