If f(x) = 24 +5, then what is the remainder when f(x) is divided by 2 + 2?
Kipish [7]

Answer:

The question is incorrect as it lacks the "x" component. Function f(x) cannot be stated without the x, elseways it couldn't be called "f(x)"

What is the solution to y-2x=3 & 3x-2y=5
timofeeve [1]

Answer:

x= -11;y= -19

Step-by-step explanation:

lets name y-2x=3    "A" ;

name 3x-2y=5        "B".

2A:     2y-4x=6

2A+B:  (2y-4x)+(3x-2y)=6+5

2y-4x+3x-2y=11

-x=11

so x= -11

so A is :  y-2 (-11)=3

y+22=3

so

y= -19

Prove that an integer consisting of 3n ones is divisible by 3n (e.g. 111 is divisible by 3, 111,111,111 is divisible by 9, etc.)
mote1985 [20]

For proof of 3 divisibility, abc is a divisible by 3 if the sum of abc (a + b + c) is a multiple of 3.

<h3>Integers divisible by 3</h3>

The proof for divisibility of 3 implies that an integer is divisible by 3 if the sum of the digits is a multiple of 3.

<h3>Proof for the divisibility</h3>

111 = 1 + 1 + 1 = 3  (the sum is multiple of 3 = 3 x 1)  (111/3 = 37)

222 = 2 + 2 + 2 = 6 (the sum is multiple of 3 = 3 x 2)  (222/3 = 74)

213 = 2 + 1 + 3 = 6 ( (the sum is multiple of 3 = 3 x 2)  (213/3 = 71)

27 = 2 + 7 = 9  (the sum is multiple of 3 = 3 x 3)  (27/3 = 9)

Thus, abc is a divisible by 3 if the sum of abc (a + b + c) is a multiple of 3.
