What are the x and y-intercepts of the line described by the equation?<br> -6x + 3y = 18.9
-BARSIC- [3]

Answer:

x-intercept - x = 1/2y - 3.15

y-intercept - y = 2x + 6.3

Step-by-step explanation:

For x,

-6x + 3y = 18.9

-6x = -3y + 18.9

x = -3y/-6 + 18.9/-6

x = 1/2y - 3.15

For y,

-6x + 3y = 18.9

3y = 6x + 18.9

y = 6x/3 + 18.9/3

y = 2x + 6.3

Find the digit that makes _ 3520 by 9
olga nikolaevna [1]
Remember the divisibility rule for 9. The sum of the digits of the number must be divisible by nine. 
Let the digit be x. Then x+3+5+2+0=x+10 has to be divisible by nine. Recalling that 18=9*2, we note that x=8.
