Given that f(x) = x^2 + 6x – 2, g(x) = x – 7, and h(x) = x + 4find each function. (f + g)(x)
Answers
Answer:
(f+g)(x) = x^2 + 7x -9
Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
= (x^2 + 6x – 2) + (x – 7)
= x^2 + 7x -9

The general formula is:
x^2 + y^2 = r^2
where x and y form the circle while r is the radius.
You already have the problem set up in its general form and you don't want the radius squared... so square root everything.
If you do that then you'll get:
x + y = 5
where 5 is the radius and NOT the radius squared. If you have questions then leave a comment. Good luck!

Final answer:
The number in question is found using simple algebra to setup and solve the equation given in the problem. The solution is n = 18.
Explanation:
The question is about finding a number (n), such that three times the number (n) is 36 less than five times the number (n). This can be solved using simple algebra.
Firstly, we setup the algebraic equation according to the problem:
3n = 5n - 36
To solve the equation, you subtract 3n from both sides to bring all n on one side:
5n - 3n = 36
Which simplifies to:
2n = 36
Now you solve for n by dividing both sides by 2:
n = 36 / 2
The result is n = 18. So, the number in question is 18.

Alright, lets get started.
The side length of square is given as 2.5.
So, the perimeter if square will be :
Once the side is doubled, means new dimension of side of square will be :
So the new perimeter will be :
The original perimeter is 10.
The new perimeter is 20.
It means the perimeter is twice the original perimeter. : Answer D

Simplifying3t + 4 = t + 13
Reorder the terms:4 + 3t = t + 13
Reorder the terms:4 + 3t = 13 + t
Solving4 + 3t = 13 + t
Solving for variable 't'.
Move all terms containing t to the left, all other terms to the right.
Add '-1t' to each side of the equation.4 + 3t + -1t = 13 + t + -1t
Combine like terms: 3t + -1t = 2t4 + 2t = 13 + t + -1t
Combine like terms: t + -1t = 04 + 2t = 13 + 04 + 2t = 13
Add '-4' to each side of the equation.4 + -4 + 2t = 13 + -4
Combine like terms: 4 + -4 = 00 + 2t = 13 + -42t = 13 + -4
Combine like terms: 13 + -4 = 92t = 9
Divide each side by '2'.t = 4.5
Simplifyingt = 4.5

The operation that Pete is using is the operation of multiplying numbers by decimal numbers and the power of 10 involved is 4
If Pete must move a decimal point to the left in 4 places, then the operation she is using is the operation of multiplying numbers by decimal numbers.
- Since the movement is to the left in 4 places, the power of 10 involves will be a 4
For example,
- if we are to convert 0.56 say to scientific notation to the power of 4. We will need to move the decimal point to the left 4 times to have 0.000056 * 10^4
Hence the operation that Pete is using is the operation of multiplying numbers by decimal numbers and the power of 10 involved is 4
