How do u do b??????????
horrorfan [7]

the assumption being that the first machine is the one on the left-hand-side and the second is the one on the right-hand-side.

the input goes to the 1st machine and the output of that goes to the 2nd machine.

a)

if she uses and input of 6 on the 2nd one, the result will be 6² - 6  = 30, if we feed that to the 1st one the result will be √( 30 - 5) = √25 = 5, so, simply having the machines swap places will work to get a final output of 5.

b)

clearly we can never get an output  of -5 from a square root, however we can from the quadratic one, the 2nd machine/equation.

let's check something, we need a -5 on the 2nd, so

\bf \underset{final~out put}{\stackrel{y}{-5}}=x^2-6\implies 1=x^2\implies \sqrt{1}=x\implies 1=x

so if we use a "1" as the output on the first machine, we should be able to find out what input we need, let's do that.

\bf \underset{first~out put}{\stackrel{y}{1}}=\sqrt{x-5}\implies 1^2=x-5\implies 1=x-5\implies 6=x

so if we use an input of 6 on the first machine, we should be able to get a -5 as final output from the 2nd machine.

\bf \stackrel{first~machine}{y=\sqrt{\boxed{6}-5}}\implies y=\sqrt{1}\implies y=1 \\\\\\ \stackrel{second~machine}{y = \boxed{1}^2-6}\implies y = 1-6\implies y = -5

At basketball practice you made 21 out of 80 shots. Which choice is closest to the percentage of shots you made?
love history [14]
Since this is a percentage, all you have to do is divide 21 from 80 and multiply that by 100
 21/80 = .2625 * 100 is 26.25

The answer closest to this is 25%, so the answer is 25%

Hope this helped! :D

What are the steps for this problem? -10-8n=n-(8n+8)
Elden [556K]

Answer:

n =  - 2

Step-by-step explanation:

- 10 - 8n = n - (8n + 8)

First, you should distribute the -1 on the right.

- 10 - 8n = n - 8n - 8

Next, add 8n to both sides. This should cancel out the 8n.

- 10 = n - 8

Now, add 8 to both sides. This will get n by itself.

- 2 = n

Your answer is n = -2.
