Simplification/ 15x^6-20x^5+10x^4
Answer:
Step-by-step explanation:
To be rational means to be able to express the result as the ratio of two whole numbers.
a) 4/7 + (-1/3) = 12/21 - 7/21 = 5/21 so rational
b) √(4) • 2/5 = ±2 • 2/5 = ±4/5 so both solutions are rational
Answer: B
Step-by-step explanation:
1. Convert gallons to quarts (1 gallon = 4 quarts)
2. Add 4 quarts to 2 1/2 quarts (6 1/2 quarts)
3. Multiply by 4 to find the amount of cups. (1 cup = 8 fl oz.)
HOPE IT HELPS BYEEEE
You would use 1.73 in order to decrease an amount by 73%
We have to find the slope of the line that passes through this points:
p1(-2,15), p2(-8,-5)
the slope of a line through two points is calculated like this:
m = (y2 - y1)/(x2 - x1)
where x1,y1,x2,y2 are the coordinates of the two points, so we have:
m = (-5 - 15)/(-8 - (-2))
m = (-20)/(-8 + 2)
m = -20/-6
m = 10/3
that is the line slope
