Answer:
f^-1(x) = -1/8x +1/4
Step-by-step explanation:
To find the inverse of a function
Exchange x and y and then solve for y
y =-8x+2
Exchange x and y
x = -8y+2
Now solve for y
Subtract 2 from each side
x-2 = -8y+2-2
x-2 = -8y
Divide by -8
(x-2)/-8 = -8y/-8
Distribute
-1/8x +1/4 = y
f^-1(x) = -1/8x +1/4
By rounding to the nearest liter, the question is asking us to round to the nearest whole number (get rid of any numbers after the decimal point). This means that we want the last number of our answer to be the number just to the left of the decimal point, which is a 3.
To determine if we should leave the number or round it up, we look to the number to the right of the 3 which is a 4. Because 4 is less than 5, we do not round up. Therefore, the answer would be 103 liters.
I hope this helps.
Correct option is C. The value of 2x = 10
Given that
10 + x is 5 more than 10
Formally, we can express this
10 + x = 10 + 5
⇒x = 15 − 10
⇒x = 5
To find 2x,
2x = 2 × x
= 2 × 5
= 10
Therefore, the value of ′ 2x ′ is ′ 10 ′
