Step-by-step explanation:
Hi there!

There are 3 parts to this equation:
f(x)
f(x+1)
4f(x)
We must first determine these three parts separately.
<u>1) f(x)</u>
We're given that
:
⇒
:
<u>2) f(x+1)</u>
Now, we must find f(x+1). To do so, add 1 to x in the original function
:
⇒ 
<u>3) 4f(x)</u>
To find 4f(x), multiply the original function
by 4:
:
<u>4) Put it all together</u>
Now, plug each of the three parts into the equation
:


Factor the left side

Divide both sides by 3^x

Because this equation is true,
is therefore true.
I hope this helps!
Answer:
a). 1/13
There are 4 5s. so 4/52
b). 3/13
12 total jack, king, and queen. 12/52
c). 15/26
30 cards are not face cards so 30/52
Answer:
10x-2y
Step-by-step explanation:
distribute for both of them then multiply both answers by 2 and add them
2(x+y)= (2x+2y) x2= 4x+4y
3(x-y)= (3x-3y) x2= 6x-6y
4x+4y+6x-6x
10x-2y
25 divided by 23 will not come out as a whole number. 23 goes into 25 1 time so the answer would be 1..... But I guess the answer would be A since that's the closest answer choice.
