Answer:
-7
Step-by-step explanation:
As x increases by 1, y decreases by 7, so the "rise"/"run" is ...
slope = rise/run = -7/1 = -7
Subtract the smaller amount ($23.04) from the larger ($29.40), and then divide the difference by 12 pounds:
$6.36
-------- = $0.53 / lb
12 lb
Answer:
1) 1/2
2) 3
3)-5
Step-by-step explanation:
to find slope: divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. so here on 1) you do (3-2)/(2-0)= 1/2.
2) (7-1)/(-1- (-3))= 6/2=3.
3) (-15-0)/(7-4)= -15/3=-5
Answer:
1.04
Step-by-step explanation:
"Complete the following sentence about the yearly rate of change in the amount of money in the account. Round your answer to two decimal places.
Every year, the amount of money in the account increases by a factor of _."
Mdecade(t) = 4900 (1.5)^t, where t is in decades.
One year is 0.1 decades, so M increases by a factor of:
1.5^0.1 = 1.04
