The point-slope form:

y-y_1=m(x-x_1)

We have

y-6=-3(x+2)\to y-6=-3(x-(-2))

Therefore

<h3>slope = -3 and the point (-2, 6)</h3>

------------

<h3>y + 2 = 2(x - 1)</h3>

2x - y = 4    <em>it's standard form Ax + By = C</em>

y = 2x - 4     <em>it's slope-intercept form y = mx + b</em>

y - x = 4 →<em> </em>x - y = -4  <em>t's standard form Ax + By = C</em>

Please help im not very sure what any of this means
BaLLatris [955]

Answer:

∠JKH and ∠GHF

Step-by-step explanation:

<em>hey there,</em>

<em />

< Corresponding means "the angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal." The lines here are parallel so they are equal.

If you don't understand the meaning of the angles also, feel free to ask me about that too.

The two angles I listed are equal to equal to each other. When you look at the other options, they aren't equal, they might look less or more degrees.

If this won't be a multiple choice but short answer, try looking at angles that look similar and see if they would be able to match with the angle given. >

<u>Hope this helps! Feel free to ask anything else.</u>

The formula v=√64h can be used to find the velocity v in feet per second of an object that has fallen h feet. Find the velocity
zhuklara [117]

Answer:

  B)  43.82 feet/sec

Step-by-step explanation:

Fill in the number and evaluate:

  v = √(64×30) = √1920 ≈ 43.82 . . . . ft/s

_____

Of course, √(64h) can be simplified to 8√h. You know that √30 lies between 5 and 6, so the velocity lies between 8·5 = 40 and 8·6 = 48. There is only one answer choice in that range.
