Find the range values of which x*x-5x+6<0

Answers

Answer 1
Answer:

Answer:between 2 and 3, not including. Interval notation: (2,3)

Step-by-step explanation:

Factor: x^2 -5x + 6 —> (x-3)(x-2)<0

Change sign to = and solve: x = 2 , 3

these are the x intercepts, the equation is not reflected over the y axis so we know the rest of the arc of the parabola is between 2 and 3

What is the reason for each step in the solution of the equation? 18−2x=4x

Answers

In order to solve an equation for a certain variable, you should isolate that variable on one side of the equation and leave all the other terms on the other side on the equation.
The, you solve to get the value of the variable.

The equation we have here is:
18−2x=4x
First, we need to isolate the terms containing the "x" on one side of the equation. To do this, we will add 2x to both sides of the equation:
18−2x+2x=4x+2x
18 = 6x
Now, we need to get the value of the "x". To do this, we will simply divide both sides of the equation by 6:
18/6 = 6x/6
3 = x .............> This is the solution of the equation
You want to get all the x's on one side of the equation so add 2x to both sides of the equation. 4x + 2x = 6x. now you want to get the x by itself so dived both sides of the equation by 6. 18 = 6x, 18/6 = x, x = 3

solve using linear combination

Answers

Idk what linear combination is but you can solve this way:
3x+y=4
-2x-y=-5
x=-1
3(-1)+y=4
-3+y=4
y=7
So x=-1 and y=7

Answer:

(-1,7)

Step-by-step explanation:

Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.
