Answer:
A.) k=0.5
Step-by-step explanation:
If we use the formula given: y=kx, we can plug in values.
0.5=k(1)
0.5=(0.5)(1)
0.5=0.5
We know that to get from 1 to 0.5, we need to divide by two, or multiple by 1/2. 1/2 in decimal form is 0.5
Answer:
Step-by-step explanation:
Substitute 4x for Y: 4x = -2x -6
Now add 2x to both sides
(due to reciprocal, the opposite of -2x is positive 2x): 4x + 2x = -2x +2x -6
Add common like terms
(4x + 2x = 6x and -2x + 2x cancel out leaving -6 alone): 6x = 6
Now get X alone by dividing the 6 to both sides: 6x/6 = -6/6
Since you're dividing a negative and a positive, the outcome will be a negative so the answer is: X= -6
Hope this helps :)
No it really does not matter.
No it is not an arithmetic sequence
Answer:
25GB was used that month
Step-by-step explanation:
Here, we want to calculate the GB used for the month.
Since we have $59.99 for 20GB, then the extra that brought the bill to $75.99 must have been from the beyond charges.
The extra charges is thus $75.99 - $59.99 = $20
Now, since $4 is charged as extra and we have a total of $20, the number of extra GB is thus 20/4 = 5
So the total GB for that month is 20 + 5 = 25GB
