Answer:
a, ax3 =b, bx3= c , cx3=d, dx3=e
Step-by-step explanation:
2, 2×3=6, 6x3=18,18 x3 =54, 54x3= 162
Multiplication of three with previous number will give you next number in series.
Answer:
This is a true statement.
Step-by-step explanation:
In order to find the line of symmetry, use the symmetry formula.
-b/2a
The variable a would be the coefficient of x^2 and b would be the coefficient of x.
-(4)/2(1)
-4/2
-2
Answer:
Step-by-step explanation:
Ok so to find constant of proportionality, you need to find K.
X would be gallons and y is cost.
To find k you need to do k=y/x
k=17.50/5
k=3.5
That's the first one. Now you need to make sure its <em>constant</em> with each one so keep going.
k=35/10
k=3.5
k=52.50/15
k=3.5
For all of those 3.5 was constant.
Because they are constant, that means the data in the graph is a proportion.
An example of an unproportional relationship would be if instead of 15 in the last column, it was 16.
k=52.50/16
k=3.28
That be different from the other 3.5's meaning its not proportional. But that's just an example.

Answer: 8 hours
Step-by-step explanation: he gets 70.40$ to work for 4 hours so you'll have to multiply 4 by 70.40 to represent it's doubling to 8 and you'll get 281.60
70.40x4=281.60
so add this 4 to the other 4 it makes 8 because that's how much it would take to get there 4 steps up to really =8
i'm sooo dificult
Given equation is:
Where T is the total cost; $36 is the entry fee per person and $60 is the one time bus parking fee.
As given, the bus holds up to 40 people, so let the total number of people be represented by 'x'
The bus holds up to 40 people so 'x' is either less than 40 or equal to 40.
Or this can be written as : 
Hence, the domain will lie between 0 and 40.
So option C : 0≤ x≤ 40 is the answer.
