Answer:
m = y/x
Step-by-step explanation:
y-y = m(x-x)
simplify:
-2y = m(-2x)
simplify again
-2y = -2mx
divide to get rid of -2 and x
-2y = -2mx
----------------
-2x

The expression Z₁ -Z₂ is 4 - (4√3 -16)i.
What is subtraction?Subtraction is mathematic operation. Which is used to remove terms or objects in expression.
The given expression Z₁ = 4 - 4√3i.
And Z₂ = -16i
Subtract Z₂ to Z₁:
Z₁ -Z₂
= 4 - 4√3i - (-16i)
= 4 - (4√3 -16)i.
Therefore, Z₁ -Z₂ is 4 - (4√3 -16)i.

Answer:
C = 94
Step-by-step explanation:
Say the centre point is Y, then the triangle BCY is an isosceles, therefore angle BCY = angle CBY
So the base points of that triangle are both 47, to find the angle of BYC, you just do:
180 - 47 - 47 = 86
and then since x is on a line with 86, and angles on a straight line add up to 180:
180 - 86 = 94
answer is 94 degrees

94

Find the rate of change of the linear function
shown in the graph. Then find the initial value.
Answer:
4 ; Initial value is (- 1)
Step-by-step explanation:
The rate of change of a linear function is slope of the line.
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
(0, - 1)
(1, 3)
m = [tex]\frac{-1-3}{0-1}[/tex] = 4
Initial value is - 1
y = 4x - 1
The equation of the graph is y = 4x - 1 with a rate of change of 4. The initial value of the function is y = -1.
What is the rate of change?The rate of change is the change of a quantity over 1 unit of another quantity.
Most of the time the rate of change is the change with respect to time.
As per the given graph,
The rate of change or slope of a function is the ratio of the difference of y's and x's coordinates.
Therefore, let's consider two points (0,-1) and (1,3)
Slope = (3 - (-1))/(1 - 0)
Slope = 4
The y-intercept is -1 so the equation will be y = 4x - 1.
The initial value of function at x = 0 is y = 4(0) - 1 = -1.
Hence "The equation of the graph is y = 4x - 1 with a rate of change of 4. The initial value of the function is y = -1".

What are the coordinates of the image of P(-2,5)
after a clockwise rotation of 90° about the origin?
Answer:
5,2
Step-by-step explanation:
Clockwise rotations for 90 is
The preimage of (x,y), or for this problem, (-2,5) into (y,-x).
So, a clockwise rotation is from x,y into y,-x
So we do -2,5 into 5,2
We flipped the x and y, and the 2 became positive because two negatives equal a positive
When a point is rotated, it must be rotated through a point.
The image of P is: (5,2)
The point is given as:
[tex]\mathbf{P = (-2,5)}[/tex]
The rule of 90 degrees clockwise rotation is:
[tex]\mathbf{(x, y) \to (y, -x)}[/tex]
So, we have:
[tex]\mathbf{(-2, 5) \to (5, 2)}[/tex]
This gives:
[tex]\mathbf{P' = (5, 2)}[/tex]
Hence, the image of P is: (5,2)

common factors of 128 and 192
Answer:
The greatest common factor of 128 and 192 is 64, because 64 is the highest number that is divisible by both numbers.
The greatest common factor of 128 and 192 is 64 because 64 is the highest number that is divisible by both numbers.
What is the greatest common factor?The greatest common factor is the largest positive number which can be divided into given numbers evenly.
In mathematics, the largest positive integer that divides each of the integers is known as the greatest common divisor of two or more integers that are not all equal to zero. The greatest common divisor of two integers is x and y.
Given that the two numbers are 128 and 192. The greatest common factor is the largest number which is divided into both numbers.
128 = 2 x 2 x 2 x 2 x 2 x 2 x 2
192 = 2 x 2 x 2 x 2 x 2 x 2 x 3
The greatest common factor is,
GCF = 2 x 2 x 2 x 2 x 2 x 2
GCF = 64

Step-by-step explanation:
We get 14 by looking at the other measurement of the triangle that was given to us. We add the two values of 196 and 1156 to find the value of c^2.To find c, we would have to take the square root of c^2 (aka 1352), which will give us 36.8. The next blank is simple, you would just add 36.8 + 14 to get 50.8 just like it is shown in the problemWrite the same answer into the last blank.Hope this helped!
