If x) = 4x^2 + 1 and g(x) = x^2 - 5, find (f + g)(x).

Vedmedyk [2.9K]

Answer:

C. 5x² - 4

General Formulas and Concepts:

Algebra I

Composite Functions
Combining Like Terms

Step-by-step explanation:

Step 1: Define

f(x) = 4x² + 1

g(x) = x² - 5

(f + g)(x) is f(x) + g(x)

Step 2: Find (f + g)(x)

Substitute: (f + g)(x) = 4x² + 1 + x² - 5
Combine like terms: (f + g)(x) = 5x² - 4

Write a slope-intercept form of the equation if it passed the

inna [77]

Answer:

$\sf\longrightarrow \boxed{\pink{\sf 3x + 4y -8=0}}$

Step-by-step explanation:

We need to write the slope intercept form of the equation which passes through (4,-1) and parallel to the line y = -3/4x .

We know that the line parallel to a given line has the same slope . Therefore the slope of the line will be , ( on comparing to Slope Intercept Form ) .

$\sf\longrightarrow Slope =\dfrac{-3}{4}$

On using point slope form ,

$\sf\longrightarrow y-y_1= m ( x - x_1)$

Substitute the respective values ,

$\sf\longrightarrow y - (-1) = \dfrac{-3}{4}( x - 4 )$

Simplify ,

$\sf\longrightarrow y +1 = \dfrac{-3}{4}x + 3$

Multiply both sides by 4 ,

$\sf\longrightarrow 4y + 4 = -3x + 12$

Put all terms on same side , i.e. on LHS ,

$\sf\longrightarrow \boxed{\pink{\sf 3x + 4y -8=0}}$

Hence the equation of the line is 3x + 4y - 8 = 0.
