\cfrac{c}{a}=r+d\implies \cfrac{c}{r+d}=a

ka=v+w\implies a=\cfrac{v+w}{k}

z=y+mx\implies z-y=mx\implies \cfrac{z-y}{m}=x$

This property says that n + 0 = n (for addition) and that 1*n = n (for multiplication). It is the ___ Property.

The property which states that multiplying a number by 1 does not change the number's value is the identity property. <span>Adding zero to a number does not change the number's value is the zero property, but some people do also call it the identity property of addition. Hope this helped!</span>

Simplify to create an equivalent expression.

Elis [28]

You would use PEMDAS so that means you would start by multiplying 3 with the parentheses 3(2+6d) on both sides then you would combine like terms so you would add 18d+18d. Then you would subtract 6- -5 on both sides then solve for a one-step equation

3(2+6d)-5=3(2+6d)-5
6+18d-5=6+18d-5
6+36d-5=6-5
1+36d=1
-1. -1
36d/36. 0/30
D=0

Complete question :

Liz's math test included a survey question asking how many hours students spent studying for the test. The scatterplot and regression line below show the relationship between how many hours students spent studying and their score on the test.

The fitted line has a slope of 15.

What is the best interpretation of this slope?

Answer:

C.)

The model predicts that the score will increase 15 points for each additional hour of study time.

Step-by-step explanation:

The slope of a regression line represents the rate of change :

From the formula :

Rise / Run = (y2 - y1) / (x2 - x1).

The slope is a Coefficient which shows how much the dependent variable changes per unit change in the independent variable.

Hence, for a slope value of +15, which is positive, meaning an increase ; then the score obtained will increase by 15 per additional unit increase in hour of study.
