Answer:
The mean is: 19
Step-by-step explanation:
Add all of those numbers up (133)
Divide it by the total amount of numbers (7)
133÷7=19

Answer: Choice D) </h3>
y + 2 = -(x - 4)
============================================
Explanation:
The slope of this line is -1 because each time we move down 2 units, we move to the right 2 units. So slope = rise/run = -2/2 = -1
The slope formula says the same thing more or less. Let's pick the two points (0,2) and (2,0) to find the slope through them
m = (y2-y1)/(x2 - x1)
m = (0-2)/(2-0)
m = -2/2
m = -1
-------------
Using that slope and a point on the line, we can form the equation. We can pick any point really as long as it's on the line. However, to have it match with the answer choices, we'll have to pick the point (4,-2)
Turn to point slope form
y - y1 = m(x - x1)
y - y1 = -1(x - x1) ... plug in the slope
y - (-2) = -(x - 4) ... plug in the point (x1,y1) = (4, -2)
y + 2 = -(x - 4)
f(x) -g(x) = -3x-5 -(4x-2)
distribute
-3x-5 -4x+2
combine like terms
-7x-3
Answer:
-7x-3
Answer: A basic theorem for finding the third length of a right angle triangle is the Pythagoras Theorem.
In a right angle triangle, the slant and usually longest side is called the Hypotenuse while the other two sides are Opposite and Adjacent.
The Pythagoras Theorem States:
Step-by-step explanation:
If for example, we are given the other two sides as 3 and 4 respectively,
Using
Hypotenuse = 
=5
These set of numbers (3,4,5) in this that satisfies the theorem are called Pythagorean Triples
