Answer:
a. 
b. No
Step-by-step explanation:
Given:
(3x-9) and 
=> the production of them is:
, we will use distributive law to solve this To do that. we first multiply by 3x then by -9. This is done as follows
= 
Then Open both brackets
= 
After that, we group the same terms
= 
=
(b) Is the product of (3x-9) and equal to the product of (9x-3) and
No, let find the product of (9x-3) and , we will use distributive law to solve this as the above example.
= (9x-3)
= 
=
= 
After that, we open the bracket to find the same terms
= 
= 
= 
As you can see ≠
Hope it will find you well.

We Know:
$220 per week.
$0.15 per mile you drive.
------------------------------------
Solution:
325 - 220 = 105
105 / 0.15 = 700
------------------------------------
Answer:
You can drive 700 miles in one week for $325!
------------------------------------
Hope this helped! Good Luck ;)
Answer:
Step-by-step explanation:
f(x) is like y in a linear equation. There is one major difference. F(x) tells you what to substitute on the right every time you see an x.
f(a) = -3a + 7
f(b) = -3b + 7
For this question a and b have values. Now work with the right side only. This is the quickest way to get the answer, but it is only marginally correct.
f(a) = -3(-8) + 7 = 24 + 7 = 31
f(b) = -3(7) + 7 = -21 + 7 = - 14
f(a) + f(b) = 31 - 14 = 17
f(a) - f(b) = 31 - (-14) = 31 + 14 = 45
Answer:
The rate at which the temperature drops.
Step-by-step explanation:
In science, the dependent variable is what you are measuring.
In math, the dependent variable is what you are evaluating.
