I find it best to switch everything exponents when taking derivatives.
F(x) = 7/x
Same as..
F(x) = 7x^-1
Take derivative..
F'(x) = -7x^-2
Plug in x = 1
F'(1) = -7(1)^-2
F'(1) = -7
Answer:
The expression is half the value of (10 + 12)
Step-by-step explanation:
We see the top part is 10 + 12
The whole thing is a fraction and 2 is in the denominator
You divide your term by your denominator, and diving by 2 is the same as 1/2 if a term.
2 and 5. 1 isn't apart of the list because the definition of a prime number is having 1 and itself as a factor. 1 only has the number 1.
$1.25p = a
I believe that is how you would formulate it.
1.25 multiplied by the amount of pounds purchased (p) equals (=) the total cost of apples (a)
