(f + g)(x) = f(x) + g(x)    

Since you know the equations of f(x) and g(x), substitute/plug it into the equation:

f(x) + g(x)     Plug in (5x³ - 7x² - 2x) into "f(x)", and (-3x³ - 9x - 3) into "g(x)"

(5x³ - 7x² - 2x) + (-3x³ - 9x - 3)        Combine like terms(terms that have the same variable and power/exponent)

5x³ - 3x³ - 7x² - 2x - 9x - 3      (I rearranged the terms to be next to their like term, the only like terms you can combine are 5x³ and -3x³, -2x and -9x)

2x³ - 7x² - 11x - 3      Your answer is the 1st option

Given the function f(x) = –0.5|2x + 2| + 1, for what values of x is f(x) = 6? x = 6, x = –5 x = 5, x = –5 x = 7, x = –6 no solut
allsm [11]

Answer:

Step-by-step explanation:

This is our absolute function for which we are tasked with finding the values of x that make the whole thing equal 6:

-.5 | 2x + 2 | + 1 = 6. Subtracting 1 from both sides gives us

-.5 | 2x + 2 | = 5. Dividing both sides by -.5 gives us

| 2x + 2 | = -10.

Because absolute value is in fact a distance measure, and one of the 2 things in math that will NEVER be negative is distance, there is no solution to this equation.

Susan uses the function p(x) = 4x to determine the perimeter of a square when she knows the side length, x. Which statements are
mr_godi [17]

We are given the function p(x) = 4x for the perimeter of the square.

Where x represents the known side length of the square.

x is the independent variable and Perimeter P is the dependent variable on x.

<em>Because value of P total depends on the value of side length x of the square.</em>

Therefore, following statement are true about the given function:

<h3>The perimeter is the dependent variable.</h3><h3>The value of p(x) depends on the value of x.</h3><h3>The length of the side of the square is the independent variable.</h3>

What are the determinants for solving this linear system?<br> 5x + 3y = 17<br> −8x − 3y = 9
Ksivusya [100]
For this case we have the following system of equations:
 5x + 3y = 17
 -8x - 3y = 9
 We can rewrite the system like:
 Ax = b
 Where,
 A = [5   3; -8   -3]
 b = [17; 9]
 x = [x; y]
 The determinant of matrix A is given by:
 lAl = ((5) * (- 3)) - ((3) * (- 8))
 lAl = (-15) - (-24)
 lAl = -15 + 24
 lAl = 9
 Answer:
 
The determinant for solving this linear system is:
 
lAl = 9
