Y-y1=m(x-x1)
x1 and y1 are coordinates of first point
x and y are coordinates of second point
(7,7) x1=7, y1=7
(-9,-1) x= -9, y= -1
-1-7=m(-9-7)
-8=m(-16)
-8= -16m multiply by -1
8=16m
m=8/16
m=1/2

Answer:

y - 7 = 1/2(x - 7)

Step-by-step explanation:

Point slope form is y - y1 = m (x - x1)

So find m = y2 - y1/ x2 - x1, so m = -1 - 7 / -9 - 7, m = -8 / -16 so m = 1/2

Then sub your (7,7) so y - 7 = 1/2(x - 7)

Given that angle a = 54° and angle b = 48°, work out 3.
natima [27]

9514 1404 393

Answer:

  x = 78°

Step-by-step explanation:

The sum of the interior angles of a triangle is 180°.

  x + a + b = 180°

  x = 180° -a -b . . . . . . . . add -a-b to both sides

  x = 180° -54° -48°

  x = 78°

How do you do this and what is the correct answer? Simple and concise explanation please!
abruzzese [7]

Answer:

Step-by-step explanation:

  • This is a neat question. I suggest that you graph it on desmos. You will lean a bunch by doing it. These are the graphs you should put on there.
  • y = 1/(abs(x - a) - 1):In red
  • When you use your down arrow, a new entry will be given you. You can use your mouse to operate the slider you get when you type a = 5
  • so your next graph should be a = 5
  • Use your down arrow again. Put in x = 4: Blue Line
  • Use your down arrow again. Put in x = 6: Green Line

Be patient with this. Play with the sliders to see what they do. I believe you are correct, but I am not certain of the second union although it does look correct.

The graph I have enclosed is of what I have described in the steps above. Make sure you try it all out.

4x+15y=13<br> 3x+5y=16 <br> solving systems by elimination
docker41 [41]
4x+15y=13 (1)
3x+5y=16  (2)
(2) * 3 --> 9x+15y=48 becomes (3)
(3) - (1) 
5x=35
x=7
sub x =7 into (1)
4(7)+15y=13
28+15y=13 
-28         -28
15y= -15
y= -15/15
y= -1 

therefore x=7 and y= -1
