Answer:
The inverse i.e f^-1 (x) is (x-1)/2
Step-by-step explanation:
The main method for finding inverse function is as follows:
We let y =f(x), and write the function as y = 2x + 1.
Next, we swap the x and y, then rearrange to make y the subject. So i.e:
x = 2y + 1 (just swapping x and y)
x - 1 = 2y
y = (x-1)/2 (solving for x).
So f^-1 (x) = (x-1)/2
X= 3
Cancel 3 out by subtracting it by itself, then subtract 3 from 18 to get 15. Now that you have 5x= 15, just divide 15 by 5x to get x= 3
Answer:
D.
Step-by-step explanation:
You got the answer right it D
(0.03) multiplied by (0.004) is 0.00012
Multiply 3 by 4 and add all the zeros together
So 0.00012
Answer:
Step-by-step explanation:
(-1,5)....x1 = -1 and y1 = 5
(-5,-5)..x2 = -5 and y2 = -5
slope = (y2 - y1) / (x2 - x1)
slope = (-5 - 5) / (-5 - (-1) = -10 / (-5 + 1) = -10/-4 = 5/2 <===
20 × 10fl ounces = 200 fl ounces
1 gallon= 128 fl ounces
200 fluid ounces equals about 1.56 gallons so
you would need to buy about two gallon bottles.
