Better labeling so I can understand.
I think( so correct me if i'm wrong).....Using the distance formula... D=Rate x Time, you alter it so that it equals time, since you want to find the number of weeks.
Time = Distance/ rate
SInce you start off at 2 and end up with 5, the total distance is 3 (I subtracted 5-2). And rate is already 12% (this is the iffy part, I'm not sure if you change the 12% in anyway.... but lets move on)
SO Time= 3miles/ 12% which is 1/4 of a week, or possibly.....
Time = 3 miles/ 0.12 which would equal 25 weeks.....
Do they give you these answers?
Answer:
Keep the exact order that is shown
Step-by-step explanation:
The first exponential already has a point at (1, -2) which means the y-intercept would be less than -2, which is the lowest among the three
The second has a y-int at -2
Third has y-int at 2
4y = -23 + 39
4y = 16
y = 4
Sub y = 4 into equation 2
7x + 6(4) = -39
7x + 24 = -39
7x = -39-24
7x = -63
x = -9
x = -9
y = 4
Answer: the large jar is cheaper
Step-by-step explanation:
If you divide the £1.54 by 440g and £1.26 by 340g, you'll find which one is cheaper per gram :
1.54/440 = 0.0035
1.26/340 = 0.0037
So, by comparing both prices/gram, you've found that the large jar is cheaper.
