Well, the form
gives the maximum (if a<0) at coordinates
, where
. If a>0, the same formula gives the minimum (there's no maximum)
22 - 5(6v - 1) = -63 First, you distribute 5 to the parentheses.
22 - 30v + 5 = -63
27 - 30v = -63
-30v = -90
v = 3
yes it can be possible to do
Answer:
The answer to your question is 189/40 kg or 4.7 kg of apples.
Step-by-step explanation:
Data
Total weight = 6.3 kg
amount of pears = 1/4
amount of apples = ?
Process
1.- Convert the total weight to a fraction
6.3 = 63/10
2.- Divide the total weight by the number of pears (4)
63/10 ÷ 4 = 63/40
3.- Subtract the previous result from the total weight
63/10 - 63/40 = 252/40 - 63/40 = 189/40
4.- Result
There are 189/40 kg of apples or 4.7 kg of apples
I'd say it's the second one because it's touching -7x and also -1y like it says in the equation
