Drupady [299]3 years ago

Since there are 12 inches in 1 foot you have to divide 84 by 12

84 divided by 12 is 7

So, there are 7 feet in 84 inches

-5x=60

The first thing we want to do is to divide -5 on both sides. We do this because -5x, is the same as -5 times x and we want to do the inverse of that.

After we divide on both sides, we get    x=60/-5

We know that 60 divided by -5 is -12.

Therefore our answer is:      x=-12

----------------------------------------------------------------------------------------------------------

5= n + 2

We always want to get the variable to be alone, so if we subtract by 5 we would be doing the opposite of getting the variable alone. Although, if we subtract by 2 on both sides, we would get the variable alone and the answer would be 3=n

Therefore our answer is:       False

----------------------------------------------------------------------------------------------------------

2(x-7)

By looking at this question, we see x being subtracted by 7. Then we see that 2 is being multiplied to that.

Therefore our answer is:        C

The product of a number and 4 increased by 8

In these types of questions, it's smart to break it up. We will start with the product of a number and 4. We know that a number is a variable and if we look at the multiple choice answers we can see that the variable they chose to use is n. We also know that a product is when numbers get multiplied. So that means 4 and n get multiplied which turns into 4n.

For the other part of the problem, we know that increased by 8 means added my 8. Now that we got our answers, we put then together.


Therefore our answer is:       A    4n+8

What’s all input for f(x)=3
defon

Answer:

all inputs are equal to <u>3</u>

Step-by-step explanation:

f(x) = 3 \\  =  3 \times 1\\  = 3  \times  {x}^{0}  \\ anything \: raised \: to \: 0 \: is \: 1 \\

\\  substituting \: any \: value \\  \: of \: x \: in \: f(x) \\ f(3) = 3 \times  {3}^{0}  \\  = 3 \times 1 \\ =  3 \\

\\ similarly \: all \: values \: of \: x \: will \\ give \: 3
