What is the product of y and 10
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.
Suppose the numbers are x and y Then the sum of their reciprocals is 1/x + 1/y = y/xy + x/xy = (y+x)/xy = 10/20 = 1/2

Put 0 in for x and solve for y to find the y intercept. Put 0 in for y and solve for x to find the x intercept. -4(0)+3y=10 y=10/3 y intercept is (0,10/3) -4x+3(0)=10 x=-10/4 x intercept is (-10/4,0)
It is: 57*10 = 570.

y = 7x-10
2x+y = 10 or y = -2x + 10 so the slope is -2
2y+5y=10 7y=10 y=10/7
