So let's just say "x" is our variable that represents the total number of students in the class. We know that 5 is 20% of x. We can also understand that 0.20x = 5. So 0.20x divided by 0.20 gives us the remaining variable, x. If we do that, we also need to divided the other side by 0.20, so 5 divided by 0.20 is 25. The answer: There are 25 students in Mrs. Conley's class.

If f(x)=1/x+2 what is f(3+h)?
Wittaler [7]
I don't know if you want the whole x+2 on the bottom or not, but I will put it on the bottom for now.
Replace x with (3+h)

f(3+h)=1/[(3+h)+2]

Now if it's supposed to be JUST x in the denominator...
Replace x with (3+h)

f(3+h)=1/(3+h)+2


Best wishes!

What is the product?
Sophie [7]

Answer:

Step-by-step explanation:

In exponent multiplication, if base are same just add the powers.

(-6a^{3}b+2ab^{2})(5a^{2}-2ab^{2}-b)=(-6a^{3}b)*(5a^{2}-2ab^{2}-b)+2ab^{2}*(5a^{2}-2ab^{2}-b)\\\\

                                             =(-6a^{3}b)*5a^{2}-(-6a^{3}b)*2ab^{2}-(-6a^{3}b)*b+ 2ab^{2}*5a^{2}-2ab^{2}*2ab^{2}-2ab^{2}*b\\\\=-30a^{3+2}b+12a^{3+1}b^{1+2}+6a^{3}b^{1+1}+10a^{1+2}b^{2}-4a^{1+1}b^{2+2}-2ab^{2+1}\\\\=-30a^{5}b+12a^{4}b^{3}+6a^{3}b^{2}+10a^{3}b^{2}-4a^{2}b^{4}-2ab^{3}\\
