1/x + 1/y y/xy + x/xy (y+x)/xy= 10/20 10/20=1/2 1/2 is the answer.
Suppose the numbers are x and y. The sum of their reciprocals = 1/x + 1/y = y/xy + x/xy = (y+x)/xy = (x+y)/xy = 10/30 = 1/3
The sum of x and y decreased by their product is (x + y)- xy.
You can set this up as follows... Let the two numbers be defined as x and y. Then, x * y = 96 x - y = 10 x = 96/y and substitute 96/y - y = 10 rearranging yields a quadratic equation 96 - y^2 = 10y or y^2 + 10y - 96 = 0 The solution(s) to the quadratic equation are given by: y = (-b +/- sqrt(b^2-4ac)) / 2a y = (-10 +/- sqrt(100 - 4(-96))) / 2 y = (-10 + 22 ) / 2 = 6 y = (-10 - 22 ) / 2 = -16 So, y can be 6 or -16 making x = 16 or -6 So you have two answers, (x,y) = (16,6) or (x,y) = (-6,-16)
To find 10 more than a given number y, you simply add 10 to y. This can be represented as y + 10. For example, if y = 5, then 10 more than y would be 5 + 10 = 15. So, the expression "10 more than y" can be simplified to y + 10.
y
x = 10, y = 25
1/x + 1/y y/xy + x/xy (y+x)/xy= 10/20 10/20=1/2 1/2 is the answer.

Yes. You must solve the two simultaneous equations below: x * y = 18 x - y = 10 When you do so, you will get two solution sets: x = 11.557 (approx.) y = 1.557 (approx.) and x = -1.557 (approx.) y = -11.557 (approx.)
the product is y=5sindn

If: 30y = 10+y Then: y = 10/29
y is 2 less than the product of 3 and x
The Y intercept of y=7x+10 is 10.
