Answer:
the estimated difference is 4
Step-by-step explanation:
The estimated difference of 12 9/11 - 8 13/15 would be rounding the fractions to a whole number
12 9/11 becomes 12 11/11 which is 13
8 13/15 becomes 8 15/15 which is 9
we rounded each fraction up since each fraction was above the half way mark so the new equation is,
13 - 9 = 4
9514 1404 393
Answer:
-1
Step-by-step explanation:
The slope formula works nicely for this.
m = (y2 -y1)/(x2 -x1)
m = (-1 -4)/(4 -(-1)) = -5/5 = -1
The slope of the line between the given points is -1.
Answer:
243.75
Step-by-step explanation:
Each choice has 7x and 3x which multiply to 21x^2.
The original trinomial has positive 20 and positive 43, so all factors of 21 and of 20 must be positive.
Only choice B has all positive terms, so choice B must be the answer.
