The value of "i" squared or 1 i by 1 i results in:
(-1)
Complex NumbersAmong the numerical sets there is one that we call complex numbers, which include values that are not real, such as "i" a letter that denotes that it is an imaginary number.
What are numeric sets?Numerical sets are groupings of numerical values that have a particularity in common, they can be integers, decimals, fractions, among others.
In function to this type of numbers there is a particular value and it is the "i" which is the result of the square root of -1, then we have:
√(-1) = i√(-1) x √(-1) = i²
[√(-1)]² = i²
(-1) = i²

Tell whether the angles are adjacent or vertical. Then find the value of x. The angles are . Question 2 x=
Answer:
Adjacent
x = 14
Step-by-step explanation:
Find the diagram attached
Adjacent angles places side by side and can also be on the same straight line. Since 5x and x+96 are on the same straight line ans placed side by side, then the angles are adjacent.
The sum of angle on a straight line is 180 degrees, hence;
5x + x+ 96 = 180
6x = 180 - 96
6x = 84
x = 84/6
x =14
The value of x s 14

Use the slope and y-intercept to write an equation for the red cab.
Answer:
y = 1/4x + 6
Step-by-step explanation:
For the red cab:
Points on the graph: (0, 6) and (8, 8)
Slope:
m=(y2-y1)/(x2-x1)
m=(8-6)/(8-0)
m=2/8
m= 1/4
Slope-intercept:
y - y1 = m(x - x1)
y - 6 = 1/4(x - 0)
y - 6 = 1/4x
y = 1/4x + 6
Answer:
y = [tex]\frac{1}{4} x[/tex] + 6
Step-by-step explanation:
The slope can be determined by taking any two random pair of points on the red line.
For example, (0,6) and (4,7)
m = y2-y1 / x2-x1 = 1/4
Your y intercept is where your line intersects on the y axis. Here, it is at y = 6.
Now, you have the slope and y intercept to write the equation of the red cab.
y = [tex]\frac{1}{4} x[/tex] + 6

Write and evaluate two equivalent numerical expressions that show Distributive Property of Multiplication
Answer:
2(x+5) = 2x+10
Step-by-step explanation:
I'm assuming you can use any possible combination of two equivalent numerical expressions for your question.
2(x+5) = 2x+10
2 times x is 2x. 2 times 5 is 10. So, you get 2x+10
The distributive property of multiplication involves taking the product a certain value and another variable joined by either an addition or subtraction operator.
3(x + 5) = 3x + 15For instance :
a(b + c) = a×b + a×c = ab + ac
The expressions below shows distributive property of multiplication :
3(x + 5) and 3x + 15 exhibits the distributive property of multiplication.
3(x + 5)
Opening the bracket :
3×x + 3×5 = 3x + 15
Hence,
3(x + 5) = 3x + 15

What is an equation of the line that passes through the point -5,7 and is parallel to the line x-5y=15
Answer:
Step-by-step explanation:
Let line to be found be Line 2
Given:
Line 1
x - 5y = 15
x - 15 = 5y
Therefore slope = 1/5
Line 2
Point = (-5,7)
Slope = 1/5
Therefore: 7 = (1*-5)/5 + c
=> 7 = -1 + c
=> c = 8
Therefore equation: y = x/5 + 8Describe the likelihood of the following statement.
You find two parallel line that intersect.
