Step-by-step explanation:
x² - 2x - 15 = 0
x1 = 5
x2 = -3
If you go from point (-1, -3) to point (4, 4), you can find the slope of the line using the slope formula.

. So our slope is 7/5. The line goes through the y axis at -3/2, so putting that together we get an equation for the line that is

, choice D from above.
$76.80 minus 12 1/2 is $64.30.
Okay. So when you solve 864/31 on a sheet of paper and you divide it properly, the remainder you get should be 27. The answer is B: 27.
Answer:
No
Step-by-step explanation:
20x2.5=50
51.79-50=1.79
therefore there isn't enough buckets for all the dirt.
