The correct answer is A) y = -3x - 1
In order to find this, start by using the two points on the line to find the slope.
m(slope) = (y2 - y1)/(x2 - x1)
m = (-4 - 2)/(1 - -1)
m = -6/2
m = -3
Since A is the only one with a -3 slope, this is the correct answer.
Answer:
Steps shown below
Step-by-step explanation:
We will simplify this using definitions and identities. Let's start.
Using 
, we have:
Using 
, we have:
Hence, proved.
Answer:
Step-by-step explanation:
The polynomial is simplified by combining like terms. Like terms are identified more easily if the variables in each term are written in the same order. We usually like to use alphabetical order. Two of the like terms have opposite coefficients, so they cancel. The result is ...
(3 1/2 -2 1/2)xy² +(-2 4/5 +2 4/5)x²y
= xy² . . . . simplified expression
__
For x = 1, y = -2, the value of the expression is ...
(1)(-2)² = 4
A is the answer because he works 2 jobs cleaning pools and mowing lawns so you would add their times together and he works 4 days a week so you would take this and multiply it by the amount of hours he works.
If you need an answer to the answer would be he works a total of 28hrs over a four day period
