Determine whether each relation is a function <br> X=-2 <br> Y=2

mash [69]

X = -2 would not be a function because if you graph it, it is a vertical line.
Y = 2 is a function because when graphed, it is shown as a horizontal line and passes the vertical line test.

Answer:

yes

Step-by-step explanation:

0.5 and 59 are very far apart- picking at random, 7 is between them. 7 is a natural number, which is a subset of rational numbers. Most numbers are rational, irrational numbers are things like pi

6+2i

aliya0001 [1]

$\frac{6+2i}{3+3i}=\frac{6+2i}{3+3i}\times\frac{3-3i}{3-3i}$
$\frac{6+2i}{3+3i}=\frac{18-18i+6i-6i^{2}}{9-9i+9i-9i^{2}}$
$\frac{6+2i}{3+3i}=\frac{18-12i+6}{9+9}$
$\frac{6+2i}{3+3i}=\frac{24-12i}{18}$
$\frac{6+2i}{3+3i}=\frac{12(2-i)}{18}$
$\frac{6+2i}{3+3i}=\frac{2(2-i)}{3}$
$\frac{6+2i}{3+3i}=\frac{2}{3}(2-i)$
$\frac{6+2i}{3+3i}=\frac{4}{3}-\frac{2i}{3}$

How do you graph a linear equation with two variables? Y= -3x-4

Minchanka [31]

First, lets break up the equation into pieces.

The first variable is slope, in your case here, we have a slope of -3 or -3/1.

The other variable is the y-intercept, which is where place on the graph where you plot (0,X), in your case here we got (0,-4). That is the y-intercept.

to graph it you have to plot the y-intercept, and then identify the slope.

Here is an example.

How do you solve 4x squared - 12x = 7 (ALGEBRAICALLY)

amm1812

$4x^2-12x=7 \\
4x^2-12x-7=0 \\ \\
a=4 \\ b=-12 \\ c=-7 \\ b^2-4ac=(-12)^2-4 \times 4 \times (-7)=144+112=256 \\ \\
x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}=\frac{-(-12) \pm \sqrt{256}}{2 \times 4}=\frac{12 \pm 16}{2 \times 4}=\frac{4(3 \pm 4)}{2 \times 4}=\frac{3 \pm 4}{2} \\
x=\frac{3-4}{2} \ \lor \ x=\frac{3+4}{2} \\
x=-\frac{1}{2} \ \lor \ x=\frac{7}{2} \\ \\
\boxed{x=-\frac{1}{2} \hbox{ or } x=\frac{7}{2}}$
