The easiest way to start this problem is to note the number of liters in the barrel right now.
That's x
You add 6 liters to that amount
You get x + 6
From that y liters are lost.
Now your total is
x + 6 - y.
If you switch the order (which you should) you get
x - y + 6
Answer: A

Step-by-step explanation:
5x2347\771=11237888
Answer:
y = -2x - 4
Step-by-step explanation:
Formula is y = mx + b where m is the slope and b is the y-intercept
(1, -6) (-3, 2)
The slope is -2
y = -2x + b
So let's find b, insert 2 for y and -3 for x to find b
2 = -2(-3) + b
2 = 6 + b
Subtract 6 from both sides to get b alone
-4 = b
We found what b equals (the y-intercept), which is -4
So, the equation is y = -2x - 4
Hope this helps and pls do mark me brainliest:)
Answer:
68 ÷ 134 = 0.5075
0.5075 * 100 = 50.75
68 of 134 = 50.75%
Step-by-step explanation:
Please be certain to use the symbol "^" to denote exponentiation. Your function y should be written as
y = x^3 + 3x2 - 2x + 4.
Principle: if the derivative of a function is negative on a certain x-interval, the function is decreasing on that interval. Thus, you must differentiate the given function: find dy/dx. Set this dy/dx = to 0 and solve the resulting equation for x. Set up intervals on the # line based upon your solutions.
For example, if x=-1 and x=2, then set up 3 intervals: (-infinity,-1), (-1,2), and (2, infinity). Looking at each interval separately, identify the interval or intervals on which the derivative dy/dx is negative.
This is a critically important skill in calculus and well worth the time and effort required to learn it.
