Answer:

a) (f+g)(x) = 6x^2 +6x -10

b) (f-g)(x) = 6x^2 -2x -4

Step-by-step explanation:

a. (f+g)(x) = f(x) +g(x) = (6x^2 +2x -7) +(4x -3)

(f+g)(x) = 6x^2 +6x -10

b. (f-g)(x) = f(x) -g(x) = (6x^2 +2x -7) -(4x -3)

(f-g)(x) = 6x^2 +2x -7 -4x +3

(f-g)(x) = 6x^2 -2x -4

Answer:

$5 {x}^{2} + 2x = 7x + 3x \\ 5 {x}^{2} + 2x = 10x \\ 5 {x}^{2} = 10x - 2x \\ 5 {x}^{2} = 8x \\ 5x = 8 \\ x = \frac{8}{5} = 1.6 \\ thank \: you$

In a small town, there are 4 times as many left-handed males as there are left-handed females, and there are 3 times as many rig

horrorfan [7]

Answer:

(b) 24

Step-by-step explanation:

The given variable definitions and the given relationships let us write these statements:

LH males = 4 × LH females = 4x

RH females = 3 × RH males = 3y

LH males + RH males = 204 = 4x +y

RH females + LH females = 348 = 3y +x

Your favorite method of solving equations of this sort can tell you ...

(x, y) = (24, 108)

There are 24 left-handed females.

<em>Additional comment</em>

Other numbers involved here are ...

y = 108 . . . . right-handed males

204-108 = 96 . . . . left-handed males (=4×24)

348-24 = 324 . . . . right-handed females (=3×108)

If you want to solve the equations by hand, you can use substitution for y to get an equation in x:

3(204 -4x) +x = 348 ⇒ -11x = -264 ⇒ x = 24
