Answer: Si se multiplica un número positivo por uno negativo, el resultado tiene signo negativo. Si se multiplican dos números con signos iguales, el resultado tiene signo positivo
Step-by-step explanation:
2pirad=360 deg
so
xrad/2pi=ydeg/360
times both sides by 360 to solve for ydeg
180xrad/pi=ydeg
so
7/9pi rad
180(7/9pi)/pi=ydeg
140=ydeg
140 deg
A is answer
1. To simplify -(x-4) change the sign on each term inside parenthesis:
-(x-4) would become -x+4
The answer is B.
2. -4xy / 3x
Cancwl the common factor out

-4y /3
The answer is C.

Mila uses the first step as multiplication to make the coefficient of x, 1
Mila maybe have multiplied the whole equation by 2 i.e.
Answer: See description below.
The residuals are the differences between the predicted values and the actual values. You will need to make a scatter plot of each difference.
Here are the five points that you will need to plot:
20 - 21 = -1 (1, -1)
17 - 16 = 1 (2, 1)
9 - 10 = -1 (4, -1)
6 - 5 = 1 (5, 1)
2 - 2 = 0 (6, 0)
