Need help with this if you can explain please do if not then just and answer is okay

pshichka [43]

Step-by-step explanation:

f(x) = x / (x - 7) = 1 + 7 / (x - 7).

The domain of f(x) depends whether the denominator of the rational expression is non-zero.

When (x - 7) = 0, x = 7.

Hence domain of f(x)

= All real values of x excluding 7. (C)

The temperature one morning in Shasta was LaTeX: -12^\circ F− 12 ∘ F. By the afternoon, the temperature had risen LaTeX: 8^\circ

Vlad [161]

Answer:

The Temperature in the afternoon was $-4\° F$ .

Step-by-step explanation:

Given:

Temperature in the morning = $-12\° F$

Rise in temperature = $8\° F$

We need to find the temperature in the afternoon.

Solution:

Now we know that;

temperature in the afternoon is equal to Temperature in the morning plus Rise in temperature in afternoon.

framing in equation form we get;

temperature in the afternoon = $-12\° F+8\° F=-4\° F$

Hence the Temperature in the afternoon was $-4\° F$ .

From complete sets of playing cards (32 cards) we pulled out one card.

AVprozaik [17]

The probability of pulling an ace is 4 out of 32 or 4/32. There are four aces in a complete set of playing cards. If you need me to simplify, it would be 1 out of 8, or 1/8. I hope this is helpful!
