Step-by-step explanation:
In triangle
x²=5²+12²
x²=25+144
x²=169
x= root of 169
x=13
So all the angles in total are going to be 180 degrees.
7+9+10 = 18 (parts at all)
180/18=10 (1 part of the ratio)
Than to find all of the angles we multiply 1 part by 7, 9 and 10 separately
10*7= 70 degrees (1st angle)
10*9=90 degrees (2nd angle)
10*10=100 degrees (3rd angle)
Answer: 70, 90, 100
It is a function because all the inputs (x values) have one output (y value).
For something to be a function, inputs can only have ONE output, if an input has multiple outputs, it is not a function.
If different inputs have the same output, it is still a function because they don't have the same input value
Answer:
-4(5x^2-2x)
-4 x 5x^2-4(-2x)
-20x^2+8x
