Answer:

(f- g)(x) = x - 3

Step-by-step explanation:

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

This means that you have to subtract the two equation.

If f(x) = 3x - 2 and g(x) = 2x + 1

Then

f(x) - g(x) = [3x - 2] - [2x+1]

= 3x - 2- 2x - 1

= x - 3

∴ (f- g)(x) = x - 3

I need help don’t understand

nadya68 [22]

If f(x)=x+1 and then x became 2, you would have the function f(x)=3. So basically for that function you would be going up three over 1. That function is already g(x)=4x. If X became 2, you would have g(x)=8x. The rate of up 8 and then over one. Because of that, g(x) would be higher

Answer:

≈ 24 cm

Step-by-step explanation:

Hi there !

c = 2πr } => c = πd => d = c/π

2r = d

replace c ; π

π =3.14

d = 74cm/3.14

= 23.5668

≈ 24 cm

Good luck !

Solve for the variable in 6⁄18 = x⁄36 A. 12 B. 6 C. 3 D. 9

RoseWind [281]

$\dfrac{6}{18} = \dfrac{x}{36}$

$\dfrac{1}{3} = \dfrac{x}{36}$

$\dfrac{1}{3} * 36 = x$ $|Multiply \ by \ 36|$

$x= \dfrac{36}{3}$ $|Divide \ both \ sides \ by \ 3|$

$x=12$

Light shines through window what is the area of a trapezoid shaped region created by the light

bogdanovich [222]

Answer:

16 ft²

Step-by-step explanation:

The complete question is attached.

A trapezoid is a quadrilateral (has four sides) with one a parallel base. The base angles and the diagonals of an isosceles trapezoid are equal.

The area of a trapezoid = [(sum of the parallel bases) / 2] * height of the trapezoid.

Given that the parallel bases are 3 ft and 5 ft, while the height of the trapezoid is 4 ft. Hence:

The area of a trapezoid = [(3 + 5)/2] * 4

The area of a trapezoid = 16 ft²
