Can someone help me on this

Step-by-step explanation:

a. supplementary

b. adds up to 180 degrees

c. 63 + 6x + 2x + 30 = 180

   3(21 + 2x) + 2x + 30 = 180

   8x + 93 =180

 8x = 87

  x = 10 7/8

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
