cell phone company Y charges a $10 start-up fee plus $0.10 per minute, x. cell phone company Z charges $0.20 per minute, x, with no start-up fee. which function repesents the difference in cost between company Y and company Z?
Answers
Cost = C
# of minutes = x
C = 0.10x + 10
Company Z:
Cost = c
# of minutes = x
c = 0.20x
Difference in cost = c - C
c - C = 0.20x - (0.10x + 10)
c - C = 0.10x - 10

According to my answer, he shound have computed 2^3 which is 8 and suibstract that from four getting four, then multiplying it by tow to get eight so it should be 4 so Miguel made no mistakes.Since he was doing the order of operations for each step of the equation.
Answer:
C. Miguel incorrectly multiplied before dividing in step 3.
Step-by-step explanation:
32 ÷ 2(2³ - 4)
Solving parenthesis and exponent.
32 ÷ 2(8 - 4)
32 ÷ 2(4)
The division is first, then multiplication.
32/2 (4)
16(4)

The solution to the system of equations is x = 2 and y = 4.
To solve the system of equations:
y = 6x - 8 ...(Equation 1)
y = -3x + 10 ...(Equation 2)
We can set the two equations equal to each other:
6x - 8 = -3x + 10
To solve for x,
6x + 3x = 10 + 8
9x = 18
Dividing both sides by 9:
x = 18/9
x = 2
So, y = 6(2) - 8
y = 12 - 8
y = 4
Therefore, the solution to the system of equations is x = 2 and y = 4.

Answer:
x = 2
Step-by-step explanation:
hey there,
< If these two are together, then the problem would look like this:
From the first equation, we can see that y = 6x-8. I am assuming in your problem you need to find what "x" is equal to, so plug in the first "y" value into the second one.
6x - 8 = -3x + 10
Bring all "x"s to one side and regular numbers to the other side.
6x + 3x = 10 + 8
9x = 18
x = 2
x = 2 is your final answer. >
