The ratio of two numbers is 7:8 After adding 15 to smaller number and subtracting is from greater the ratio becomes 6:5 find the numbers?

  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.

30

step-by-step explanation:

idk

i hope i

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
