First, you just need to disregard the greater than sign because these types of equation is solved the same way as those with equals (=) sign in the middle. So when y=6,
First you need to substitute y=6 to the y in 3y

3(6)>2x

By multiplying,

18>2x

By dividing both sides of the equation by 2

18/2 > 2x/2

9>x

However if you want to transpose x to the left side of the equation, you also need to reverse the sign to <

Which means

X<9

If y=6 them we will have

3*6>2x
18>2x
 
x must be smaller than 9, because 
18=2*9  => 18=18, and we doesn't respect the rule

now that we know that x<9 we have other 2 cases...
1. x is a natural number x can take values from the interval [0, 8]
2. x is a rational number, so it can take values from the interval [8, - infinite)

<h2>Answer:</h2>

Our functions are:

f(x) = -5x + 12\\g(x) = -\frac{3}{2}x + 4\\

To solve this, we must use the expression g(-10) - f(3).

-\frac{3}{2}(-10) + 12 - [-5(3)] + 12\\\\15 + 12 - [-5(3)] + 12\\\\15 + 12 - (-15) + 12\\\\27 - (-15) + 12\\\\42 + 12\\\\54

The value of the expression g(-10) - f(3) is <em>15</em>.

PLEASE ANSWER NUMBER 32!!!
Leni [432]

Answer:

N < -3

Step-by-step explanation:

first off, simply, then subtract the 9s from both sides.

5n < -6 -9

Simplify -6 -9 to -15 , Which gives you

5n < -15

then, divide both sides by 5.

n < 15/5

Simplify 15/5 to 3, Which give you

N < -3

here is your answer.

N < -3

Prove that if n is an even integer, then n + 1 is odd. Give a proof by contraposition of this theorem.
S_A_V [24]

Answer:

Proved below

Step-by-step explanation:

If we assume that n + 1 even when n is even, it means that;

n + 1 = 2x

Where x is an integer

Then;

n = 2x - 1

This means that n is odd because 2x - 1 is odd.

But we know that n is even, thus, our assumption is wrong.

Therefore, n + 1 is odd when n is even.
