\\ \sf\longmapsto \dfrac{3}{x-4}=\dfrac{6}{x-5}

\\ \sf\longmapsto 3(x-5)=6(x-4)

\\ \sf\longmapsto 3x-15=6x-24

\\ \sf\longmapsto 3x-6x=-24+15

\\ \sf\longmapsto -3x=-9

\\ \sf\longmapsto x=\dfrac{-9}{-3}

\\ \sf\longmapsto x=3

\\ \sf\longmapsto KM=3+6=9

What is the solution to y = x + 2 and y = 3x – 2 and how do you know? PLEASE HELPPPPP! THANK U!
Nutka1998 [239]

Answer:

(2,4)

Step-by-step explanation:

We have the system:

y=x+2

y=3x-2.

This is already setup for substitution.

I'm going to replace my first y with what the second y equals.

That is, I'm going to write 3x-2=x+2.

Time to solve the following for x:

3x-2=x+2

Subtract x on both sides:

2x-2= 2

Add 2 on both sides:

2x. = 4

Divide both sides by 2:

x. = 2

Now that we know x=2 and we have an equation that relates x to y: either y=x+2 or y=3x-2, doesn't matter which we use, we can find y.

So we y=x+2 with x=2 which means y=2+2=4.

So the solution, the intersection, is (2,4).

1. What is the transformed quadratic equation of 3x2 + 5x = 6 in the form of ax2 + bx + c = 0?
Murljashka [212]

Answer:

That will be;

3x^2 + 5x -6 = 0

Step-by-step explanation:

Here, we want to write 3x^2 + 5x = 6 in the form

ax^2 + bx + c = 0

That will be;

3x^2 + 5x -6 = 0

We can simply get it by bringing the value 6 from the right hand side of the equation to the left hand side of the equation
