Answer:
We can check this two ways: distributing the -0.5, and plugging in a number for x.
First, we can check this by distributing the -0.5. Our equation becomes:
-1.5x -2.5 = -1.5x + 2.5
Clearly, this is not true. We can show this one more time by plugging in a number for x. I will use 2.
Now, we evaluate both sides and see if they are equal.
-3 - 2.5 = -3 + 2.5
-5.5 = 0.5
Clearly, this is not true. These expressions are not equivalent.

Answer: 645 letters per hour
Step-by-step explanation:
Given : After t months on the job, a postal clerk can sort letters per hour.
Then the average rate at which he clerk sorts mail during the first 4 months on the job, we put t= 4 , we get
Hence, the average rate at which he clerk sorts mail during the first 4 months on the job = 645 letters per hour
You have to Isolate y
15x-3y=2
-15x
-3y = -15x+2
/-3. /-3 /-3
Y= 5x - 2/3
Answer:
<h2>The value of
</h2>
Step-by-step explanation:
given slope=
the the points and (2, y)
now, the slope of and (2, y) are equal to
<h2>so
</h2>
cross multiplication, we get
<h2>
</h2><h2>
therefore the value of </h2>
