21 = 5n-2(n-3)

21 = 5n-2n+6

21-6 = 3n

n=15/3

n=5

5=n because you multiply -2 times n then -3 then you add -2n with 5n then subtract 6 from both sides and finally divide by 3

Nicholas says that (2^6)(2^6) equals 2^12, which also equals 4^6. is this true? PLEASE EXPLAIN
Umnica [9.8K]

When you multiply two numbers in exponential notation whose bases are the same, you just keep the base the same and add the exponents.

In this case, you have (2^6) * (2^6) = 2^(6 + 6) = 2^12.

We can change the base of 4^6 into 2:

(2^2)^6

Is this the same as 2^12? Well, when we have an expression like that above, we multiply the exponents together, so we get: (2^2)^6 = 2^12.

Therefore, Nicholas is correct.

When x = -2 h (x) = |-2x-6|
stich3 [128]

Answer:

Step-by-step explanation:

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2.

so you must first find what is the x and which one is the y in the function then you will find the answer when you solve the problem
