Answer:
I think it would be 3.24x10^26
Step-by-step explanation:
Answer:
I will assume that the term "x+2/2" is meant to be "(x + 2)/2)." Otherwise the equation would read (x/3) = x + 1
Step-by-step explanation:
(x/3) = (x + 2)/2
x = 3*(x+2)/2 [Multiply both sides by 3]
x = (3x + 6)/2
x = (3/2)x + 6/2
x - (3/2)x = 3
-0.5x = 3
x = -6
====================
Check:
Does (x/3) = (x + 2)/2 for x = -6?
(-6/3) = (-6 + 2)/2
-2 = -4/2
-2 = -2 YES

Answer: the cost per minute of call made in a month is $0.15
the flat monthly fee that the customer pays is $20
Step-by-step explanation:
Let x represent the cost per minute of call made in a month.
Let y represent the flat monthly fee that the customer pays.
If a customer uses 490 minutes, the monthly cost will be $93.50. This means that
490x + y = 93.50 - - - - - - - - - -1
If the customer uses 880 minutes, the monthly cost will be $152. This means that
880x + y = 152 - - - - - - - - 2
Subtracting equation 1 from equation 2, it becomes
- 390x = - 58.5
x = - 58.5/ - 390
x = 0.15
Substituting x = 0.15 into equation 1, it becomes
490(0.15) + y = 93.50
73.5 + y = 93.5
y = 93.5 - 73.5 = 20
Answer:
The function is
domain is 0 to 0.2 hour.
range is 0 to 2 miles.
Step-by-step explanation:
Given that,
Average velocity = 10 miles/hour
Time = 12 min = 0.2 hour
We need to write a function that models the student's distance from home
Using formula of distance
Where, v = velocity
t = time
d = distance
Put the value into the formula
This is a function.
We know that,
Domain :
Domain shows the time.
So, domain = 0 to 0.2 hour
Range :
Range shows the distance.
The range at t =0,
Put the value of t in the function
The range at t =0.2 hour
So. range = 0 to 2 miles
Hence, The function is
domain is 0 to 0.2 hour
range is 0 to 2 miles
