Answer:
Hey there!
Our equation can be: 
.
When y is 3, we could have 
.
Let me know if this helps, or if you need more help :)
Answer:
Answer is x=3+0.05/5
Step-by-step explanation:
5x+19.95=35
We move all terms to the left:
5x+19.95-(35)=0
We add all the numbers together, and all the variables
5x-15.05=0
We move all terms containing x to the left, all other terms to the right
5x=15.05
x=15.05/5
x=3+0.05/5
I hope it's helpful!!
If f={(-1,-3), (1,1),(2,3),(4,6)} and g={(-1,-1),(1,7),(4,3)} what is (f+g)(4)?

Answer:
(f + g)(4) = 9
Step-by-step explanation:
We have that:
f = {(-1,-3), (1,1),(2,3),(4,6)}
this means that:
f(-1) = -3
f(1) = 1
f(2) = 3
f(4) = 6
and we also know that:
g = {(-1,-1),(1,7),(4,3)}
hich means that:
g(-1) = -1
g(1) = 7
g(4) = 3
Now we want to find:
(f + g)(4)
For the general case of two functions f(x) and g(x)
(f + g)(x) = f(x) + g(x)
Then:
(f + g)(4) = f(4) + g(4)
and we know both of these values, so we can just replace them:
(f + g)(4) = f(4) + g(4) = 6 + 3 = 9
Then we get:
(f + g)(4) = 9
Answer:
x = 16 because if you multiply that and then divide
9.6 guests which isn't technically possible so it has to be 10 according to my calculations
