Which equation is the inverse of 2(x-2)squared=8(7+y)

dsp73

Answer:

$f^{-1}(x)=2(+/-)2\sqrt{(7+x)}$

Step-by-step explanation:

we have

$2(x-2)^{2}=8(7+y)$

step 1

Exchange x for y and y for x

$2(y-2)^{2}=8(7+x)$

step 2

isolate the variable y

$(y-2)^{2}=4(7+x)$

take the square root both sides

$y-2=(+/-)\sqrt{4(7+x)}$

$y=2(+/-)\sqrt{4(7+x)}$

step 3

Let

$f^{-1}(x)=y$

$f^{-1}(x)=2(+/-)\sqrt{4(7+x)}$

$f^{-1}(x)=2(+/-)2\sqrt{(7+x)}$ ----> equation of the inverse

How many groups of 1/5 are in 4

snow_lady [41]

Answer:

Step-by-step explanation:

To find this, we need to figure out what 1/5 is as a decimal

5/5 = 1, so 5 groups of 1/5 equals 1

Multiply this by 4, 20 groups of 1/5, or 20/5 = 4

Now we confirm this

1/5=0.2

4/0.2=20

So it is true

Hope this helps!^^
