Answer:
4y - y^2 = 10
Step-by-step explanation:
Let x and y be the two numbers
x+y = 4
xy = 10
Taking the first equation and solving for x
x = 4-y
Substituting this into the second equation
(4-y) *y = 10
4y - y^2 = 10
Answer:
A
Step-by-step explanation:
y = -9 ------(1)
9x -4y = -9 -------(2)
substitute (1) into (2)
9x - 4 (-9) = -9
9x = - 45
x = -5
there you go, x = -5 and y = -9
so. (-5 , -9 )

Answer:
3 5/12
Step-by-step explanation:
4 3/4 - 1 1/3
3 x 3/4 x 3
4 9/12 - 1 1/3
1 x 4/3 x 4
4 9/12 - 1 4/12
4 - 1 = 3
9/12 - 4/12 = 5/12
3 5/12
