<span>Options B and D
The domain of a function is the values that can be input into the function and the range of a function is the possible outputs from the function. Since Wong can use up to 10 canisters, the domain would be all integers between 0 and 10 inclusive. And since he uses exactly 3 balls per contained, the range will be all integer multiples of 3 ranging from 0 to 30 inclusive. Examining the available options, only option "B" is correct about the range (you can't have fractional containers, so option A won't work). Option "D" is correct for the range.</span>
Answer:
12
Step-by-step explanation:
the number = x
2/3 of x =8
2x/3 = 8
2x= 24
x=12
In this problem why is the easiest to substitute.
Just set the equations equal to each other because they both equal y
-x + 4 = 2x - 8
(You want to get all the x's to one side so add x to each side)
4 = 3x - 8
(next add 8 to both sides)
12 = 3x
(lastly divide 3 from both sides)
4 = x
You have got your x so now it is time to find that y just replace x to either of the two equations
y = 2(4) -8 or y = -(4) + 4
y = 8 - 8 y = 0
y = 0
Final Answer: y=0, x=4
1. You're not dumb don't ever say that about yourself
2. #3 is y= -3/2x+6.5, #6 is y= -3x-5, and #9 is y= 3x+8
