What is (f+g) (x)???
Answers
Answer:
A.
Step-by-step explanation:
To get to the answer, add both f(x) and g(x) together. This would be (2x^2 +3x -4) + (-4x^2 + 5x - 8). Remember that adding a negative number is the same as subtracting the positive of that number, for example, 3 + (-4) is the same as 3 - 4.

Answer:
Option C. $1,285 more Dylan need to save.
Step-by-step explanation:
Dylan's essential (fixed) expenses = $900 per month
His essential (flexible) expenses = $400 per month
His non-essential expenses = $295 per month
Total expenses per month = 900 + 400 + 295 = $1595.00
He wants an emergency fund of 3 times monthly living expenses
= $1595 × 3 = $4,785.00
currently, in Dylan's emergency fund account = $3,500
Dylan need to save more = 4,785 - 3,500 = $1,285.00
Dylan need to save $1,285 more to have an adequate emergency fund.

Answer:
3 is the root of the equation.
Step-by-step explanation:
We have to find the root of the polynomial equation x(x-2)(x+3)=18.
We can find the same by using a graphing utility and the system of equations.
We can make two equations which are given by
Now, we plot the graph of these equations and the x-coordinate of the intersection point will be the root of the equation.
the graph has been shown in the attached file.
The intersection point is (3, 18) and the x-coordinate is 3.
Therefore, 3 is the root of the equation.
It has four choses and you didn't show the right one, answer is 3.
