Answer:
The Commutative Properties of Addition and Multiplication ... in an addition expression can be grouped in different ways without changing the sum. ... Mathematicians often use parentheses to indicate which operation should be done ... Rewrite 7 + 2 + 8.5 – 3.5 in two different ways using the associative property of addition.
Step-by-step explanation:
I learned this and i still know it. I dont have a explanation
We observe that the relationship between the variables is linear.
Therefore, we look for an equation of the form:
![b = m * a + b ' ](https://tex.z-dn.net/?f=b%20%3D%20m%20%2A%20a%20%2B%20b%20%27%0A)
Where,
m: slope of the line
b ': intersection with the y axis
a: independent variable
b: dependent variable
The value of b 'occurs when a = 0.
We have then:
![b '= -10 ](https://tex.z-dn.net/?f=b%20%27%3D%20-10%0A)
(See table)
Then, the value of the slope is found using the following formula:
![m = \frac{b2-b1}{a2-a1}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7Bb2-b1%7D%7Ba2-a1%7D%20)
Substituting values:
![m = \frac{-7-(-10)}{1-0}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B-7-%28-10%29%7D%7B1-0%7D%20)
Rewriting:
![m = 3](https://tex.z-dn.net/?f=m%20%3D%203%20)
Thus, the linear equation is:
![b = 3*a-10](https://tex.z-dn.net/?f=b%20%3D%203%2Aa-10%20)

Answer:
The equation is:
C.) 3a-b=10
Easy way to do this is to get a calculator and type 8.65 then push the log button and that will give you the answer
log 8,65 = 0.9370
Answer: the answer is really -8 (A)
Step-by-step explanation: because how do 0 make since u can't divide 3x and -8
