Solve x − 2y = 3 for x.
wolverine [178]

Answer:

x=2y+3

Step-by-step explanation:

So we have the equation:

x-2y=3

And we want to solve for x. In other words, we want to isolate the x-variable.

So, add 2y to both sides of the equation.

(x-2y)+2y=(3)+2y

On the left, the 2y cancel. Simplify the right:

x=2y+3

And we're done!

I need to find all real values of x from this inequality x^2&gt;2x-2 and also this question x^2&gt;2x+2. I need the answer fast
sergeinik [125]

x^2\gt2x-2

x^2-2x+2\gt0

You are essentially asking at this point where is the quadratic function greater than 0. To get the interval find the roots. Between the roots the function is guaranteed to be LESS THAN zero. Everywhere else the function is greater than 0.

x^2-2x+2=0

Use Vieta's rule to get the roots,

(x-1)(x-1)=0

Both roots are the same so no value is less than 0 which means all values except at the point of root are strictly greater, the point of root is at x_{1,2}=1 which means the set for which the quadratic function is greater than 0 is \mathbb{R}-\{1\} "all real numbers except 1".

To convert this into interval notation use all numbers up to 1 but not including and all numbers after 1 but not including,

(-\infty,1)\cup(1,\infty)

Hope this helps :)

Make sure to focus on the arms and feet of the man.<br> It’s my final <br> Set for 100 points !
Paha777 [63]

Shoes= 10

Man= 5

Tie= 4

So, 10+5*4= 30 <— Answer

How to get variables:

Shoes:

3 shoes are equal to 30, so to find the value of the shoes use 3x=30. X=10

Man:

2 men and a shoe is equal to 20. So, 2x+10=20

2x=10

X=5

Tie:

2 ties and a man are 13. So,

2x+5=13

2x=8

X=4
