There is a rule:
One input(x-value) can only have one output(y-value) in order to be a function.
If one input has more than one output, it is not a function.
(This doesn't apply to outputs, one output can have more than one input and still be a function)
(2,10),(4,15),(6,20),(8,25)
This is a function because each input only has one output.
Your answer is A
Answer:
f and b
Step-by-step explanation:
if you put them in y-intercept form, both slopes are 3
In b. it's easy to see that 3x has a slope of 3.
In f. it's not so obvious. Just solve for y or use the shortcut m = -a/b where a is the coefficient of x and b is the coeff of y.
hence -(6/-2)=3

Answer:
7,200
Step-by-step explanation:
McKenzie's commission for the month is ...
0.12 × 45,000 = 5,400
When that is added to McKenzie's base pay, she makes a total of ...
5,400 +1,800 = 7,200
McKenzie makes 7,200 in a month when she sells 45,000 worth of cars.
You could divide 5 in half and then add that to the five to find the amount of flour to use in a triple recipe. Hope this helps.
That would equal 36 so yes it is rational
