Answer:
y represents the total amount he spent in x amount of rides+ the $10 fee.
Step-by-step explanation:
At x=0, y=10 because he needs to pay $10 to enter, and he haven't rode on anything yet.
x=1, y=12
x=2, y=14
x=3, y=16
... and so on.
Step-by-step explanation:
450 - 396 = 54
(54/450) * 100% = 12%
Hence the decrease is 12%.
Distribute then multiply 6x to all the terms inside parenthesis remember order of operations starting from left to right when solving expressions so the when you distribute
is 30x3-6x2 the 3 and 2 after x represent x cubed and squared
Answer:
150
Step-by-step explanation:
Since y is directly proportional to sqrt((x+2)^2), there is a constant,k, such that
y=ksqrt((x+2)^2)
We are given a pair (x,y) in this relation. Let's plug in (8,250 ) to find k.
250=ksqrt((8+2)^2)
250=ksqrt((10)^2)
250=k10
250/10=k
25=k
So for any pair (x,y) we have the relation y=25((x+2)^2).
We are asked to find y when x=4.
y=25((4+2))^2
y=25(6)
y=150
Test to see if y is proportional to sqrt((x+2)^2)
For the given points: 250/150=10/6
The equation is true so we're great.
Answer:
NOT a function!
Step-by-step explanation:
A function is a relation where each input has only one and ONLY one output. For example, for the number 2 in a relation, that number 2 can only have one other y value it is paired with, it can not have more than one.
For example, in this problem the number 2 is stated twice. One set has (2, -8) and (2, 8), so that means this input has more than one output. Therefore, this relation is NOT a function.
