Answer:

10 fewer minutes

Step-by-step explanation:

Use formula

distance = time* speed

The distance between home and school:

4* 30 min = 4 * 0.5 hr = 2 miles

Noah's time to reach home:

2 / 6 = 1/3 hr = 1/3*60 min = 20 min

Difference in time:

30 min - 20 min = 10 min

What form is this equation in? y + 6 = (1/2)(x - 4)

maks197457 [2]

Y +6 =(1/2)(x+4)

y +6 = 1/2 x +2
y=1/2 x - 4

or 1/2 x -y = 4

Let f(x) = √x-5 Find f^ -1.

iris [78.8K]

Answer:

$f^{-1}(x)= x^2 + 5 \,,\,\,x\geq 0$

Step-by-step explanation:

Use the method of swapping x and y and isolating y.

$f(x) = y = \sqrt{x-5}\,,\,\,\,x\geq 5,y\geq0\\\\f^{-1}:x=\sqrt{y-5}\,,\,\,\,y\geq 5, x\geq 0\\x^2 = y-5\\y = x^2 + 5 = f^{-1}(x)\\$

Note that domain/range will be swapped as well.
