X-y=200
xy=mn
so
first equation times -1 and add x both sides
y=x-200
sub that for y in other equation
x(x-200)=min
x²-200x=min
take deritivive
2x-200=min
find where it equals 0
2x-200=0
2x=200
x=100
y=x-200
y=100-200
y=-100
the numbers aer 100 and -100
Answer: f(-7) = 0
For the factored form of f(x), if x = -7, then one of the factors will be equal to 0, since (-7 + 7) = 0. This will cause the entire y-value to be 0, because anything multiplied by 0 = 0.
X + y = 138
x - y = 88
--------------------------
x + y = 138
-x
y = -x + 138
--------------------------
-> substitute " -x + 138" into y
x- (-x+138) = 88
x + x - 138 = 88
2x - 138 = 88
+ 138
2x = 226
2x/2 = 226/2
x= 113
---------------------------
-> substitute "113" into x to get y
113 - y = 88
-113 -113
-y= -25
y = 25
---------------------------
Our final answers are the two numbers "113" and "25"
I think 15. I’m not sure if it’s addition but I think it’s 15
