I got disconnected from my tutor, can't reconnect. need an explanation ​

The absolute value function |<em>x</em>| always returns a non-negative number. It takes any number <em>x</em> and returns <em>x</em> if it's already non-negative, or -<em>x</em> if it is negative in order to make it positive.

|x|=\begin{cases}x&\text{for }x\ge0\\-x&\text{for }x

For the equation

-3 + 4 |2<em>x</em> - 5| = 14

rearrange terms to get

|2<em>x</em> - 5| = 17/4

Now,

• if 2<em>x</em> - 5 ≥ 0, then |2<em>x</em> - 5| = 2<em>x</em> - 5. Then

2<em>x</em> - 5 = 17/4

• and if instead 2<em>x</em> - 5 < 0, then |2<em>x</em> - 5| = -(2<em>x</em> - 5), so that

-(2<em>x</em> - 5) = 17/4, or

2<em>x</em> - 5 = -17/4

In the first case,

2<em>x</em> - 5 = 17/4

2<em>x</em> = 17/4 + 5 = 37/4

<em>x</em> = 37/8

In the second case,

2<em>x</em> - 5 = -17/4

2<em>x</em> = -17/4 + 5 = 3/4

<em>x</em> = 3/8

Difference between ellipse circle parabola and hyperbola equations
belka [17]
The equation of a circle is:

(x - h)² + (y - k)² = r²

The equation of a parabola is:

(x - h)² = 4p(y - k)

The equation of an ellipse is: 

\frac{(x-h) ^{2} }{ a^{2} }  +  \frac{(y-k) ^{2} }{ b^{2} }  = 1

where variables a and b and the two different measurements of the vertices

The equation of a hyperbola is: 

\frac{((x-h)^{2} }{ a^{2} } -  \frac{(y-k)^{2} }{ b^{2} }  = 1 if it is with a horizontal transverse axis

\frac{ (y-k)^{2} }{ b^{2} } -  \frac{ (x-h)^{2} }{ a^{2} }  = 1 if it is with a vertical transverse axis

Notice these have a subtraction operation, the exact opposite ellipse.

Answer:

Step-by-step explanation:

M is 24 degrees and so assuming that x is almost on the line m is. I would pick 24 because X is almost on the same line as M
