Write an equation to model this situation. Then complete the input-output table below; and graph the equation on the coordinate plane provided. If two quantities x and y are directly proportional to one another, (meaning if x is doubled, so is y; if x is tripled, so is y), they show direct variation.
(a+b) + c = a + (b + c)
re-arrange the numbers - associative property of addition
Answer
Associative property of addition
A+b=-3, a=-3-b
ab=-35, and using a from above we get:
(-3-b)b=-35
-3b-b^2=-35
b^2+3b-35=0
b≈-7.6033 and 4.6033
So the two numbers are approximately -7.6033 and 4.6033
