\begin{cases} v=5i-7j\\\\ w=3i+2j \end{cases}\qquad \begin{cases} < \stackrel{a}{5}~~,~~\stackrel{b}{-7} > \\\\ < \stackrel{a}{3}~~,~~\stackrel{b}{2} > \end{cases}\qquad \qquad \stackrel{magnitude}{\sqrt{a^2 + b^2}} \\\\[-0.35em] ~\dotfill\\\\ ||v||~~ - ~~||w||\implies \sqrt{5^2+(-7)^2}~~ - ~~\sqrt{3^2 + 2^2}\implies \sqrt{74}-\sqrt{13} ~~ \approx ~~ 5

Write the equation of the line that has an undefined slope and passes through the point (3,5)
Arlecino [84]

Undefined slope is when a line becomes vertical. Vertical lines have undefined slope because if we attempt to find the slope using formula, the denominator will become 0 which is undefined.

Next, the equation of a vertical line is x = a where a is any real numbers.

Since the line is vertical, for any a-value would have same y-value which is all real numbers.

However since the graph passes through x = 3. For x = 3 has y-value as set of all real numbers.

Answer

  • The equation for a line that has undefined slope and passes through (3,5) is x = 3

Let me know if you have any doubts!

X-y+z for x= 18,y=6,z=1
kkurt [141]

Answer:

We have been given the equation: x+y+z. Now these are variables. Thus, we have to fill in the values given: where x = 18, y = 6 and z = 1. Let's fill these values in.

<em>x+y+z</em>

<em>= 18+6+1</em>

<em>= 18+(7)</em>

<em>= 25</em>

Hope it Helps. Good luck on your assignment! (brainliest if possible)

mylen [45]

Answer:

x = 5

Step-by-step explanation:

(3-6x)/3 = -11

first multiple both sides by 3

3 - 6x = -33

then subtract 3 from both sides

-6x = -30

then divide by 6

x = 5
