Given the functions, f ( x ) = x2 + x - 5 and g ( x ) = 4 x2 - 2 x + 1, perform the indicated operation. When applicable, state

elixir [45]

Answer:

(f-g)(x) = - 3 x² + 3 x -6

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given function f(x) = x² + x - 5

g(x) = 4 x² - 2 x + 1

(f-g)(x) = f(x) - g(x)

= x² + x - 5 - (4 x² - 2 x + 1)

= x² - 4 x² + x + 2 x - 5 -1

= - 3 x² + 3 x -6

(f-g)(x) = - 3 x² + 3 x -6

(8,-7)m=-3/4 write an equation in point slope form of the line that passes through the given point and has the given slope

Paladinen [302]

Answer:

Equation of the straight line in point-slope form

y -(-7) = $\frac{-3}{4}$ (x-8)

Equation of the straight line

3x +4y +4=0

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that the point ( 8,-7) and $m = \frac{-3}{4}$

Equation of the straight line passing through the point (x₁, y₁) and having slope 'm'

y - y₁ = m (x-x₁)

y -(-7) = $\frac{-3}{4}$ (x-8)

4( y+7) = -3(x-8)

4y +28 = -3x +24

3x +4y +28 -24 =0

3x +4y +4=0
