Answer:
x = 75
Step-by-step explanation:
Given information from the question:
x - 3y = 30
y = 15
We can substitute y = 15 into the equation to find x.
x - 3(15) = 30
x - 45 = 30
x - 45 + 45 = 30 + 45
x = 75
Answer:
22
Step-by-step explanation:
So, first, we can find out how many home runs the coach hits in one game
So, 18 home runs in 9 games, so we can do 18 ÷ 9=2
So, he hits 2 home runs per game
But, we have to find for 11 games
So, we do 2*11(Runs times number of games) and get 22
Hope this clarified

Answer:
The answer is -14 .
Step-by-step explanation:
Using BODMAS rule.... at first solve the bracketed problem... then you wm get your answer!
You have a lot of questions here, I can help with some.
1) To find the inverse, switch the x and f(x) and solve for f(x).
x = 3f(x) - 7
x + 7 = 3(f(x)
(x + 7) / 3 = f(x)
2) It is a function, because each input pairs with only 1 output.
3) Any diagonal line would be a function.
4 - 8 (We can't do without the diagram)
9) f(-9) = 3(-9) - 6
f(-9) = -27 - 6
f(-9) = -33
10) f(-2) = 42 + 3
f(-2) = 45
