Answer:
There are 10 pigs and 30 chickens
Step-by-step explanation:
Let the number of pigs be x
let the number of chickens be y
Then there are 40 heads . So the total number of pigs and chickens is 40
x + y = 40-----------------------(1)
We know that pigs have 4 legs and chickens have 2 legs
4x + 2y = 100----------------------(2)
Solving (1) and (2)
multiply (1) by 2
2x + 2y = 80-------------------------(3)
subtract (3) from (2)
4x + 2y = 100
2x + 2y = 80
----------------------------
2x = 20
----------------------------

x = 10
Now Substituting x in (1), we get
10 + y = 40
y = 40 - 10
y = 30
Answer:
45 eggs left
Step-by-step explanation:
if they had 4 crates and each crate has 18, then we have a total of 72 eggs
subtract 27 eaten eggs from 72
72-27=45
they have 45 eggs left
The value of f(0) is 12.
<h3>What is graph?</h3>
Graph is a mathematical representation of a network and it describes the relationship between lines and points.
By considering the graph we have to find f(0) which means we have to find that point where x- coordinate is zero.
Also, which shows that 12 the function f(x)
So, taking the point is (0,12) we can get f(0)= 12.
