Answer:
(2,-8)
Step-by-step explanation:
y have
y=3x-14
y=x-10
we can substitute y in the first equation with x-10
x-10=3x-14
solve for x
4=2x
x=2
Now that we know what x equals we can solve for y
3(2)-14
6-14
-8=y
(2,-8)
P(red) first drawn:
20/36=5/9
P(red) second drawn:
19/35
95/315 or 19/63. As a result, the probability that both marbles are red is 19/63. Hope it help!

Answer:
f(x) = 5x - 30
Yes it is a function
Step-by-step explanation:
Because when you input 0 you get -30 we know it starts at 0 or (0,-30). This gives us b in the equation y = mx + b.
We know that for every 4 cars washed it increases by 20. So 20/4 is 5. This tells us m = 5.
Plug it all in and you get y = 5x - 30 or f(x) = 5x - 30
