An angle passes through the point (-7,-5). What is the compass heading of this angle?

1 answer:

3 0

To find the angle use arc tan (-5/-7) which simplifies tips arctan(5/7). arc tan is tan to the power -1, which is also called inverse tan. The heading of the angle, if you drew this out on a graph your angle would be in the third quadrant and therefore the heading is south of west.

Explain why a graph that fails the vertical-line test does not represent a function

Anon25 [30]

For any given y value, there can only be one x value. Let's consider a graph with a line that curves and intersects x=2 twice. This would mean that if you plug 2 into the function you would get two answers. However, this is not possible as plugging in any value to x will result in only one answer. For example, if y= 4x + 3, no matter how many times I plug a number in there, I'm always going to get the same y value, and this is true for all real functions.

We are first ask to translate this equation. So using the correct notation...

3X-9=6x6/4

We can also solve it.

3x-9 = 6x6/4

3x-9 = 36/4

3x-9 = 9

3x = 18

x=6

answer: X=6

What is the value of k in the equation StartFraction k Over 3 EndFraction minus 5 = 34?

12345 [234]

$\huge\text{$k=\boxed{117}$}$

$\displaystyle\frac{k}{3}-5=34$

To find the value of $k$ , we need to isolate it on one side of the equation. Add $5$ to both sides of the equation, then multiply both sides of the equation by $3$ .
