Answer:

x = 4y - 1/120y, y ≠ 0

Step-by-step explanation:

First, let's subtract 2x from both sides of the equation:

2x + 5 ⋅ 3y ⋅ 8x - 2 - 2x = 2x + 4y - 3 - 2x

Simplify:

5 ⋅ 3y ⋅ 8x - 2 = 4y - 3

Multiply the 5 ⋅ 3 ⋅ 8:

120xy - 2 = 4x - 3

Add 2 to both sides of the equation:

120xy - 2 + 2 = 4x -3 + 2

Simplify:

120xy = 4y - 1

Divide both sides by the 120y:

120xy/120y = 4y/120y = 1/120y; y ≠ 0

So,

x = 4y - 1/120y, y ≠ 0

I hope this helps!

How many is 6 less than 14

frez [133]

Hello, My Dear Friend!

What is 6 less than 14?
We are looking for a new number which is 6 less than 14. 
We will get the new number by subtracting 6 from 14. 
We write it down as:

$14-6=8$

And finally the solution for: What number is 6 less than 14?

Is 8 !

Therefore, That Is The Correct Answer!^^^

Would the answer be 0 ?

BartSMP [9]

Answer:

Step-by-step explanation:

For it to be continuous at x=0 we need the left and right limit at x=0 to be equal. We also need those limits to equal what happens at x=0.

A famous limit is:

As x goes to zero, sin(x)/x goes to 1.

So the left limit at x=0 would be 4(1)=4.

The right limit at x=0 would be a-2(0)=a.

So a=4.

So f(0)=4-2(0)=4 also which is what both limits would equal for x=0 if a=4.

Is 79.45 a rational number

joja [24]

Answer:

79.45 is a rational number, but not a whole number.

Step-by-step explanation:

A rational number is obtained by dividing one integer by another one to get an integer result. For example, 2/3 equals the rational 78/100 or 842-32=814 that are both integers, which means that they are both valid representation of it. Non-integers are called irrational numbers. Irrationals are also obtained through division sometimes but they do not always end up being an integer at the end even though they still have a finite decimal value for their denominator or numerator (i). Euler's Constant, for instance has the decimal expansion 2.719926... repeated indefinitely and so cannot be represented as an integral.
