Answer:

D, x = 3

Step-by-step explanation:

to know if a line is parallel, we need to know what kind of line x = 6 is

we can use the mnemonic VUX/HOY to determine the slope, the type of line, and which axis it corresponds to. VUX/HOY stands for:

Vertical line

Undefined slope

X axis

Horizontal line

0 is the slope

Y axis

according to this, the equation x = 6 is a vertical line

now we can start eliminating answer choices

A. a line containing the point (6,2)

the point lies on the line x = 6, as the x-coordinate in the ordered pair is 6. this is not parallel to the line

B. y = 6

this intersects x = 6 and is not parallel

C. y = 4

this intersects x = 6 as well and is not parallel

D. x = 3

this leaves us with x = 3, which is a vertical line as seen by the equation and therefore x = 3 is our answer

marishachu [46]

Answer:

$\large\boxed{x=2\dfrac{3}{4}}$

Step-by-step explanation:

$4\dfrac{11}{18}-x=1\dfrac{31}{36}\qquad\text{subtract}\ 4\dfrac{11}{18}\ \text{from both sides}\\\\4\dfrac{11}{18}-4\dfrac{11}{18}-x=1\dfrac{31}{36}-4\dfrac{11}{18}\\\\-x=1\dfrac{31}{36}-4\dfrac{11\cdot2}{18\cdot2}\\\\-x=1\dfrac{31}{36}-4\dfrac{22}{36}\\\\-x=1+\dfrac{31}{36}-4-\dfrac{22}{36}\\\\-x=(1-4)+\left(\dfrac{31}{36}-\dfrac{22}{36}\right)\\\\-x=-3+\dfrac{31-22}{36}\\\\-x=-3+\dfrac{9}{36}$

$-x=-3+\dfrac{9:9}{36:9}\\\\-x=-3+\dfrac{1}{4}\qquad\text{change the signs}\\\\x=3-\dfrac{1}{4}\\\\x=2\dfrac{4}{4}-\dfrac{1}{4}\\\\x=2\dfrac{4-1}{4}\\\\x=2\dfrac{3}{4}$

The terminal side of θ passes through the point (10, 6). What is the exact value of cos θ in simplified form?

seraphim [82]

Answer:

$\frac{5\sqrt{34}}{34}$

Step-by-step explanation:

The formula for cos θ is a/r. A is the first number (10) and b is the second number (6). R is the hypoteneuse which can be found through r = $\sqrt{a^{2} + b^{2} }$ .

In the equation you'd write that as r = $\sqrt{10^{2} + 6^{2}$ which can be simplified to $\sqrt{136$ .

You end up with $\frac{10}{\sqrt{136} }$ and you simplify this by doing $\frac{10 }{\sqrt{136} } * \frac{\sqrt{136} }{\sqrt{136} }$ , ending with the result of $\frac{5\sqrt{34}}{\sqrt{34} }$ .

(I also got this answer right on the test.)
