If y varies directly as x, and y = 15 when x = 10, then what
is y when x = 6

y = 9.

Step-by-step explanation:

y = kx where k is a constant.

Substituting the given values:

15 = k*10

k = 15/10 = 1.5 so

y = 1.5x is the relation.

When x = 6

y = 1.5 * 6

= 9..

50

Step-by-step explanation:

0 is larger then -50 and you want the difference so minus them

0-(-50) now when 2 negative signs meet like this they turn to addition

0+50 which is 50

their difference is 50
