They are 7 points away from each other.
Im not sure what you are trying to ask but any investment can be risky, yes.
X is the number
sum means add
sum of half a number and 4 means
(x/2)+4
result is -16
(x/2)+4=-16
minus 4 both sides
x/2=-20
times 2 both sides
x=-40
the number is -40
They don't seem equivalent, the first set yields 4+3xy and 7xy. The second set yields 10-(6/y) and 4/y. R u sure u typed in the question correctly?
Answer=9
To solve this, we just have to find a number that, when added to -4, make a total of 5, and when multiplied by -4 make a total of -36.
x+-4=5
x*-4=-36
9 fits the parameters for both of these
9+-4=9
9-4=5
5=5
9*-4=36
36=36
