Lydia buys 5 pounds of apples and 3 pounds of bananas for a total of $8.50. Ari buys 3 pounds of apples and 2 pounds of bananas
Anarel [89]
5x + 3y= 8.50
3x + 2y= 5.25

Lydia is the first equation. She bought 5 pounds of apples which is x and bought 3 pounds of bananas which is y. Basically, remember each banana and apple weighs a price per pound. We don't know the price so we just put an x. This is the same for the second equation

Please help domain&range
zubka84 [21]

Answer:

21, 7.5, -6

Step-by-step explanation:

Think of domain as x and range as y

okay so basically sense your range is (-6, 3, 12) and your function is

f(x) = -2/3x + 8

your domain values would be

21

7.5

-6

I suggest using desmos, it's very helpful, hope this helps

To compare unit prices, you first have to find the unit prices
for whistles, the unit prices are:
$21.25/25=0.85
36/50=0.72
60/80=0.75
difference between the highest unit price and the lowerest: $0.85-$0.72=$0.13 

Kazos: 10/25=0.40
18.5/50=0.37
27.20/80=0.34
so the highest unit price is $0.40
