is this correct?
a * b = -70
a + b = -9......a = -9 - b
b(-9 - b) = -70
-b^2 - 9b + 70 = 0
(-b + 5)(b + 14) = 0
-b + 5 = 0
5 = b
b + 14 = 0
b = -14
ur numbers are -14 and 5
-14 * 5 = -70
-14 + 5 = -9
In order to solve for a variable, you need to get it by itself on one side of an equation. Depending on the equation, there are different steps to do that.
Anyway, the value of 5 is 50 and the value of 6 is 6 as in the ones place.
Answer:
For finding the inflection points you'll have to put the first derivative equal to zero and solve for x. After you've done that, you can plug in the x you've just found into the original function and find also the y, so you'll find the ordered pair (x,y) of the inflection point(s).
B and F
the x coordinates shift one to the right, so that's B.
the image flips over the x axis so the y coordinates become negative
