Answer:
no solution
Step-by-step explanation:
y = -2x + 3
6x + 3y = -3
the substitution method means you plug one equation into the next, because the first equation gives us a solution for y we can go ahead and plug that into y of the second equation
6x + 3(-2x + 3) = -3
6x - 6x + 9 = -3
9 = -3
which is false meaning that there are no solutions and the lines don't touch at any point
A) 6x -5y = 5
B) 3x + 5y = 4
Adding the equations:
9x = 9
x = 1
A) 6*1 -5y = 5
A) 6 - 5 = 5y
A) 5y = 1
y = 1/5 = .2
The answer is 10 x and i think complementary but i could be wrong so you may want someone else to answer that
Answer:
50, 60, 50, and 60
Step-by-step explanation:
xy = 3000
2x + 2y = 220
Rewrite the second equation
y = -x + 110
Substitute this into the first equation.
x(-x + 110) = 3000
-x^2 + 110x - 3000
Divide by -1
x^2 - 110x + 3000
(x - 60) (x - 50)
x = 60, 50
When x = 60, y = 50 and vice versa, so the sides are 50, 60, 50, and 60.
