Use the formula
n(n-1)/2
which is the total number of connections between n points
So,
4(3)/2 = 6
the answer is option C.
Hope this helps
Step-by-step explanation:
Given function is,

Where,
y = amount paid to the gym in dollars
x = number of months
So when x = 0, y =55(0)+80 = 80
i.e when number of months is 0, you have to pay a fee of $80.
This is the one time fee to open a membership.
After that for each month you have to pay $55 for each months.
So 55 is multiplied with x.
(a^3b)^2 • 4ab^3
a^6b • 4ab^3
4a^6b+1b^3
1 less than or greater than -2
Answer:
one solution
Step-by-step explanation:
2(2b-4)+5=7+2b
4b - 8 + 5 = 7 + 2b
4b -3 = 7 + 2b
4b - 2b = 7 + 3
2b = 10
b = 10/2
b = 5.
it can have only 5 as solution that will be only one solution if we change the value of 5 to other number then the answer will be wrong
