Step-by-step explanation:

L = 3w

2L + 2w > 56

sub for L

2(3w) + 2w > 56

6w + 2w > 56

8w > 56

w > 7

Check: L = 3(8)

L = 24

2(24) + 2(8) > 56

48 + 16 > 56

What is the inverse of the function f(x) = 2x + 1?

timama [110]

Answer:

(a) h(x) = 1/2x -1/2

Step-by-step explanation:

The inverse of the function y = f(x) is found by solving x = f(y).

<h3>setup</h3>

x = f(y)

x = 2y +1 . . . . . . use the definition of f(x)

<h3>solution</h3>

x -1 = 2y . . . . . subtract 1

(x -1)/2 = y . . . . divide by 2

y = 1/2x -1/2 . . . . eliminate parentheses

h(x) = 1/2x -1/2 . . . write in functional form

The inverse of f(x) = 2x+1 is ...

h(x) = 1/2x -1/2

So, y-intercept is (0,3) and x-intercept is (3/7,0)

Step-by-step explanation:

We are given:

$y=-7x+3$

We need to find y-intercept and x-intercept

Finding y-intercept

To find y-intercept we put x =0

Solving:

$y=-7x+3\\y=-7(0)+3\\y=3$

So, y-intercept is (0,3)

Finding x-intercept

To find x-intercept we put y =0

Solving:

$y=-7x+3\\0=-7x+3\\-7x=-3\\x=-3/-7\\x=3/7$

So, x-intercept is (3/7,0)

So, y-intercept is (0,3) and x-intercept is (3/7,0)
