Step-by-step explanation:

Look at the picture.

$\bold{DOMAIN:}\ 3\leq x$

Function? NOT, because for x∈(3, 5) the relation has two values of y.

The vertical line test.

If the vertical line you drew intersects the graph more than once for any value of x then the graph is not the graph of a function (picture 2).

Write an equation parallel to the line

Schach [20]

The easiest way to find a parallel equation is to write your equation in slope-intercept form. The general equation for slope-intercept form is y = mx + b, where m = the slope of the equation, b = the y intercept, and x and y are your variables.

You're given 5x + 10y = -4.
1) Move 5x to the right side by subtracting 5x from both sides:
5x + 10y = -4
10y = -5x - 4

2) Divide both sides by 10 to get y by itself on the left. Simplify:
$10y = -5x - 4\\
y = - \frac{5}{10} x - \frac{4}{10} \\
y = - \frac{1}{2} x - \frac{2}{5}$

<span>Remember that for parallel lines, the slope, m, is the same for both equations. You can make the y-intercept, b, whatever number you want.

When the equation is in slope-intercept form, </span> $y = - \frac{1}{2} x - \frac{2}{5}$ , you can see that $m = - \frac{1}{2}$ .

A parallel equation is in the form:
$y = - \frac{1}{2} x + b$

Plug in anything you want for b. One example is: $y = - \frac{1}{2} x + 3$

-------

Answer: $y = - \frac{1}{2} x + 3$ (just one example)

Find the value of x.

pychu [463]

Knowing that all triangles angles add up to 180*:

24* + x + ? = 180*

Knowing the straight line is 180*:

180* - 122* = 58*

The equation then is:

24* + x + 58* = 180*

Then solve for X:
