To find the decimal form, you have to manually divide 1 by 8. Since 8 is greater than 1, the quotient would then start with 0., then you add a 0 next to 1, to make it 10. This time, divide 10 by 8. The nearest answer would be 1, because 1 *8 = 8. Subtracting this from 10, you get 2. Add another 0 to 2, to make it 20. Do the cycle all over again. The complete solution is as follows:
0.125
---------------------------
8 | 10
- 8
------------------------
20
-16
-------------
40
- 40
-------------
0
<em>Hence, the decimal form of 1/8 is 0.125.</em>
We can write the function in slope-intercept form (y + mx + b). Since we have the slope, we can solve for the y-intercept.
y = -2x + b
4 = -2(0) + b
4 = b
Input the data we have now.
y = -2x + 4
Since we are dealing with a function switch out the y for f(x)
f(x) = -2x + 4
Best of Luck!
Answer: 24
Step-by-step explanation:
The store will charge $3.90 for the bag of chips.
Reason for this is do 1.2*225%(or 2.25) in your calculator to get 2.7.
Then take the 2.7 then add it to the original purchase cost of 1.2 to give you a total of $3.90.
