K= -3/4 would be your answer
Calll x the smaller negative number.
The larger number will be x + 8
The product will be x(x+8) = 308
An the equation:
x^2 + 8x = 308
x^2 + 8x - 308 =0
If you solve that equation you will get x = -22 and x = 14.
The result that you are looking is the negative, x = -22.
The larger number is -22 + 8 = -14.
(-22)*(-14) = 308
Answer: x^2 + 8x - 308 =0
2/15 + 27/35 = 14+81 /105 = 95/105 = 19/21
so, your answer is 19/21
Basically the first thing you're going to have to do is move the y's to one side of the equal sign. To do this you can either add 0.3y to both sides of the equation OR subtract 0.7y from both sides of the equation.
