-5 + 4 = -1
The answer is 4
Given that,
Total no of cards = 20
The ratio of animal cards to fruit cards is 2:3
No of animal cards = 20
Solution,
Let there are 2x animal cards and 3x fruit cards. ATQ,
2x+3x = 20
5x = 20
x = 4
Animal cards = 2x
= 2(4)
= 8
Fruit cards = 3x
= 3(4)
= 12
It is also mentioned that, of the cards, 1/3 have bananas on them. It means,
![B=\dfrac{1}{3}\times 12\\\\=4](https://tex.z-dn.net/?f=B%3D%5Cdfrac%7B1%7D%7B3%7D%5Ctimes%2012%5C%5C%5C%5C%3D4)
Hence, 4 cards have bananas on them.
Take out the largest common number
In this case is 6
6(3x + y)
hope this helps
you can factor 6 out of both
To find the inverse function simply replace "x" by "y", replace "y" by "x", and solve for y
f(x)=4x
y=4x
x=4y
y=x/4 or h(x)=(1/4)x
