Step-by-step explanation:
Let or be equal to the amount of plant food that remains after each day.
be the number of days that have passed.
Total amount of plant food used is 72 mm.
Number of days the experiment goes on is 6 days.
Plant food used each day is .
So, the function will be
at
Value of is the domain which is .
Value of is the range which is .
Answer:
Flip the second number
Step-by-step explanation:
To divide by a fraction, you simply flip it over and multiply
Take # 7 as an example:
5 / becomes 5 X
Of course to make a whole number you put a 1 under it:
5 becomes
Then you multiply straight across (top X top and bottom X Bottom)
Lastly, simplify as needed:
2 /
Make the two a fraction and flip the fraction you are dividing with:
which reduces to 6
To remember the steps use Keep it, Change it, Flip it.
Keep the first number, change from division to multiply, and flip the fraction you were going to divide by.
Answer:
For your first answer it is because they are two different ways to solve the equation
Step-by-step explanation:
For Example!
<h2>Solution 1:</h2>
(x-4)² – 28 = 8
The 8 is positive making it a different equation (this is like absolute value). (I am assuming you know the answer to the probelm)
<h2>Solution 2:</h2>
(x-4)² – 28 = -8
The 8 could be negative meaning that when you add the 28 to the right side it is -8+28 which will be a negative!

Since h(x) =18 all you have to do is plug in 18 into the x, and then in would be h(18) = 2(18) + 4. If you multiply first it would be h(18) = 36 + 4. All you have to do is add 4 to 36, which would equal h(18) = 40
