Slope intercept form is y = mx + b
y = -2x + 4
-x² - x + 6
First thing I would do is distribute out that negative. Your new problem is:
- (x² + x - 6)
Now, factor the inside. We need to find products of - 6 that when added together have a sum of positive 1. They are 3 and - 2.
- (x² + 3x - 2x - 6)
Group together and find your factors. I'm going to short cut and go right to them for the sake of space and time.
- (x + 3)(x - 2)
Your answer is Option B
Answer:
$154.20
Step-by-step explanation:
To find a percent of a number, multiply the percent by the number.
20% of $771 =

The increase is $154.20
Answer:
52.4 seconds.
Step-by-step explanation:
The total time for the 3 runs = average time * 3
= 49.8 * 3
= 149.4 seconds.
The time for the third run = 149.4 - 45.2 - 51.8
= 52,4 seconds.
