Answer:

y-4=m(x+8)

Step-by-step explanation:

point slope form is y-y1=m(x-x1) where y1 is the y in the point the line passes through, and x1 is the x in the point the line passes through.

So, you can put in (-8,4) in as I did.

Also, since the x in the point the line passes through is a negative, and two negatives make a positive, that's why the x-x1 part changes into x+8

Hope my explanation makes sense!

Answer:

Point-slope equation is

y-y1 = m(x-x1)

m is a slope, m=5/4

y1 = -5, x1 = 8

Point-slope equation is

y+5 = 5/4(x - 8).

Find x.<br> I had been stuck on this one for awhile

Arlecino [84]

Answer:

34 degrees

Step-by-step explanation:

ok so 180-111=69

then the opposite angle from 37 is also 37

the the missing angle from the left triangle has to be 103

so then the angle below x is 77

and so we know x = 34 degrees

I hope that made sense.

Factor 10x3 + 8x2 - 6x.

valkas [14]

We notice a factor of 2x in both 2x(5x^2+4x-3) trial and error (5x-3)(x+1) yeilds 5x^2+2x-3, nope (5x+3)(x-1) yeilds 5x^2-2x-3, nope (5x-1)(x+3) yeilds 5x^2+14x-3, nope (5x+1)(x-3) yeilds 5x^2-14x-3, nope simplest form is 2x(5x^2+4x-3)

What is the volume of a square based pyramid with a side 11 cm and a perpendicular height of 20 cm

Kaylis [27]

V=lw*h/3

So since its a square l and w are the same

11*11 = 121

h=20

20/3= 6.6666666

V=121*6.6666666

V= 806.66667

Determine value of k

Ipatiy [6.2K]

72+k is equal to 180. So if you set up a equation if looks like:

72+k=180

Subtract 72 from both sides

K=108°

Your answer is 108°

URGENT

kupik [55]

The best way to approach this problem is to look at the graph of the given function. Replace values of x from 1 to 24 to indicate the numbers of hours in a day. As seen on the graph, there is only one point where the port is at high tide. That would be at 1:00 am.

Looking at the graph, it would be safe for the boats to be in the port when the graph levels off at around 10 to 24. That's from 10 am to before 12 midnight. Then, they would have to stay away between 12 midnight to before 10 am.
