Answer:

For $f(x)=g(x)$ we can take any value of x =0,1,2,3 etc

Step-by-step explanation:

Given the system

f(x)= $2x$

And g(x)= $2x$

We have f(x)= g(x)= $2x$

Therferore , the graph of two function is coincident line .

The solutions from graph of two functions are infinite because both functions are the same .

Therefore, the value of both functions are same at every value of x.

Therefore, we can choose more tha one value of x.

For examaple, at x=0

f(x)=0 and g(x)=0

At x=1 we get

f(x)=2

And g(x)=2

At x=3 we get

f(x) = $3\times2=6$

g(x)= $3\times2=6$

Therefore , we can see at every value of x the value of two functions are same.

Therefore, we can take x=0,1,2,3,4

If F(x) =g(x) =2x,
x can be any value

Pls help for number 6

A: 45x + 30y = 1350
Since we don’t know how many adults and children are in the group, we use x and y

b: x-intercept= 30 y-intercept=45
To find the x-intercept you need to isolate the variable. 45x/45 = x
Then you do the same thing to the other side. 1350/45 = 30
So x=30
Same thing with the y-intercept.
30y/30 = y 1350/30 = 45
y=45 (Not really sure what it means by “what they represent” but I thinks it’s that there are 30 adult tickets and 45 children tickets )

c: so our points are (30,0) and (0,45) so you would graph that.
To find how many children tickets were bought if there were 20 adult tickets just look at the photo I put. I don’t know how to explain this.

Hope this helps
