Answer:
The answer to your question is:
Step-by-step explanation:
If the line is rotated, we get the perpendicular of the initial line.
See the attachment, the blue line is the original and the red one is the new line.
Process
new slope = 2/5
Point ( 0, 4)
(y - y1) = m (x - x1)
( y - 4) = 2/5 (x - 0)
y - 4 = 2/5 x
y = 2/5 x + 4 New line
<span>¿Cuál es el monto total que pagaron?</span>
D:12 or B: -1 im hope good luck
The first place and 15th place are already decided, so we have to find the number of <span>different ways that the </span>other<span> 13 students can line up, in the places from 2 to 14.</span>
2nd place can be any one of 13 people. For each of those . . .
3rd place can be any one of 12 people. For each of those . . .
4th place can be any one of 11 people. For each of those
13th place can be any one of 2 people. For each of those
14th place has to be the one student who is left.
Total number of ways that 13 students can line up in places 2 through 14 is
(13 x 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1)
<span>That number is called "thirteen factorial". The number is </span>6,227,020,800<span> . </span>
<span>When you write it in math, you write it like this:</span><span>13</span>
Answer:
5
Explanation:
So for these, a triangle always equals 180 so you just have to set it up where you add all the sides together to equal 180. Also because it is an isosceles triangle, it means that the two bottom angles are equal so start by setting them equal and solving for x:
75 = 3x
So divide both sides by 3:
25 = x
Now you really didn't have to solve for x because you already know that it equals 75, so you could just said x doesn't matter and just treat it like a 75, but I explained it just in case.
So now that you have your base angles which added together equal 150 lets set it all equal to 180:
4y + 10 + 150 = 180
Now I will simplify this:
4y + 160 = 180
subtract 160 from both sides:
4y = 20
now divide both sides by 4:
y = 5
hope this helps!
