Answer:
r=-3
Step-by-step explanation:
-----(A)
Here we are given that
![(x_1,y_1) = (2,r)](https://tex.z-dn.net/?f=%20%28x_1%2Cy_1%29%20%3D%20%282%2Cr%29%20)
![(x_2,y_2) = (-5,11)](https://tex.z-dn.net/?f=%20%28x_2%2Cy_2%29%20%3D%20%28-5%2C11%29%20)
And the value of m is -2
Replacing them in (A)
![-2=\frac{11-r}{-5-2}](https://tex.z-dn.net/?f=%20-2%3D%5Cfrac%7B11-r%7D%7B-5-2%7D)
![-2=\frac{11-r}{-7}](https://tex.z-dn.net/?f=%20-2%3D%5Cfrac%7B11-r%7D%7B-7%7D)
![-7 \times -2=11-r](https://tex.z-dn.net/?f=%20-7%20%5Ctimes%20-2%3D11-r)
![14=11-r](https://tex.z-dn.net/?f=%2014%3D11-r)
![r=11-14](https://tex.z-dn.net/?f=%20r%3D11-14)
![r=-3](https://tex.z-dn.net/?f=%20r%3D-3)
Hence the value of r is -3 and the coordinate is(2,-3)
Chen might lisen 160 classical songs
you add them all the song
then you you divide how many song there are by 360
it should equal 40 so you multipythat by 4
(I hope i got that right)

14 plus 17.5 minus 90 (the degree of a right angle)
Answer:
the answer is 908. You need to compare the sides.
16 in x 20 in= 320 in
42in x 14 in = 588
all together it's 908
Answer:
17 + 123 (4 - 1) + (36 / 18) 52 =
17 + 123 x 3 + 2 x 52 =
17 + 369 + 104 =
17 + 473 =
490
