Answer: 1. X+2

2. 6x-3

3. -2x-1

4. 9x5

Step-by-step explanation:

1. X+4-3+1 There is only one variable, so you don’t need to worry about that. Just do all of the numerical operations. 4-3+1= 2. So it would be x+2

2. X-5+5x+2. Again, do the numerical operations first. -5+2=-3. X+5x=6x. So it would be 6x-3.

3. 2x+7-4x-8. 7-8=-1. 2x-4x=-2x. So it would be -2x-1.

4. (4+3)x+2x-5. Do the operation in the parenthesis first. Then it would be (7)x or just 7x+2x-5. Simplify to 9x-5.

Answer:

Subtracting 3x^2+4x-5 from 7x^2+x+9 results in a polynomial. After subtracting 4x^2-3x from this polynomial the difference is 14

Step-by-step explanation:

The question given is:

Subtracting 3x^2+4x-5 from 7x^2+x+9 results in a polynomial. After subtracting 4x^2-3x from this polynomial the difference is?

First we will Subtracting 3x^2+4x-5 from 7x^2+x+9

7x^2+x+9-(3x^2+4x-5)\\=7x^2+x+9-3x^2-4x+5\\Combining\:like\:terms\\=7x^2-3x^2+x-4x+9+5\\=4x^2-3x+14

So, the polynomial we get is: 4x^2-3x+14

Now, subtracting 4x^2-3x\: from\: 4x^2-3x+14

4x^2-3x+14-(4x^2-3x) \\=4x^2-3x+14-4x^2+3x\\Combining\:like\:terms\\=4x^2-4x^2-3x+3x+14\\=14

The difference is 14

So, Subtracting 3x^2+4x-5 from 7x^2+x+9 results in a polynomial. After subtracting 4x^2-3x from this polynomial the difference is 14

Myles is tracking the growth of his palm tree. it was 62 inches when he bought it, and it has grown 6 inches per year. what does
Gre4nikov [31]
  • The initial value represents the height of the palm tree when the tree was first bought.
  • The input for the initial value is 0.
  • The output for the initial value is 62 inches.

What is initial value?

It is given that,

The height of the palm tree at the time Myles bought it was 62 inches.

He is tracking the growth of the tree and he has observed that it has grown 6 inches per year.  

So, the initial value of the tree, here, is representing the height of the palm tree when it was bought.

As can be seen clearly, there is no input for the initial value. And, the output for the initial value is given to be 62 inches.

Rufina [12.5K]

The result of the exponential expression is 81

<h3>Indices expressions</h3>

Indices are written in term of exponents

According to the expoenent law of indices

a^4 = a * a * a * a

Given the expression

(-3)^4

This means the product of -3 in four places. Mathematically

(-3)^4 = -3 * -3 * -3 * -3
(-3)^4 = 9 * 9
(-3)^4 = 81

Hence the result of the exponential expression is 81
