Answer:
The answer is C
Step-by-step explanation:
OK, so you know the equation y = mx + b?
To find the slope, divide rise/run
Since the line is going down, that means the slope is negative.
See which y has x = 0
In this case it’s -1
so it has to be C
Answer:
2x^2 - 6x + 7 - (5x^2 + 2x - 8)
Distributive a -1 to each term in the parentheses.
2x^2 - 6x + 7 - 5x^2 - 2x + 8
Combine like terms.
-3x^2 - 8x + 15 is the expression after being subtracted.

Answer:
9 square kilometers
Step-by-step explanation:
Let's round the width to 2.0 kilometers, and round the length to 4.5 kilometers.
We know that area is length times width, so
A = lw
A = 2.0*4.5
<u>A = 9.0 square kilometers</u>
If we do this on the calculator, it's around 9.36 square kilometers, so our estimate was good.
Answer:
x = 5/7 is your answer.
Step-by-step explanation:
What you do is get x by itself.
<em>4x + 8/7 = 4</em>
<em>4x = 2 6/7</em>
x = 5/7 is your answer.
