A line passing through the point (7, 6) has a slope of 2.

Masja [62]

An equation in point-slope form is
y - y1 = m (x - x1)

Your point is (7,6) and your slope is 2
y1 is the y coordinate of your point (in this case 6)
x1 is the x coordinate of your point (in this case 7)
m is your slope (in this case 2)

Now you just have to plug these numbers in:
y - 6 = 2 (x - 7)

paul is diving and is 3.5 feet below sea level. he is descending at a rate of 0.5 feet per minute. if paul is now at 12 feet how

andrezito [222]

Answer:

He has been diving for 17 minutes

Step-by-step explanation:

* Lets explain how to solve the problem

- Paul is diving and is 3.5 feet below sea level

- He is descending at a rate of 0.5 feet per minute

- Paul is now at 12 feet

∵ His initial position is at 3.5 feet below the sea

∵ He is descending, that means he is moving down

∵ His final position is at 12

∴ He is descending a distance = 12 - 3.5 = 8.5 feet

∵ He is descending at a rate of 0.5 feet per minute

∵ He is descending 8.5 feet

∵ Time = distance ÷ rate

∴ His time of descending = 8.5 ÷ 0.5 = 17 minutes

* He has been diving for 17 minutes

Given p || q and ∠4 = 130°, find the measure of angles 1, 2, 3, 5, 6, 7, and 8. Label on the diagram.

lana [24]

1 = 130
2 = 50
3 = 50
5 = 130
6 = 50
7 = 50
8 = 130

1 and 4 are the same because of the vertical angle

If BCDE is congruent to OPQR, then DE is congruent to _____. (Options are attached)

aev [14]

This congruency thing is all about corresponding sides and angles. In quadrilateral BCDE and OPQR, DE and QR are in corresponding positions. You don't even have to draw them out to see that. Just like you can say that angle B and angle O are corresponding, and side BC is corresponding to side OP. Match them up; that's all there is to it!
