Answer:
(1, 2)
Step-by-step explanation:
Subtract the second equation from the first:
(y) -(y) = (6x -4) -(-x +3)
0 = 7x -7 . . . . . simplify
0 = x - 1 . . . . . . divide by 7
1 = x . . . . . . . . . add 1
y = -1 +3 = 2 . . . substitute into the second equation
The solution is (x, y) = (1, 2).
That is negative since the elevator is decreasing. If the elevator was going up, it would be positive.
Step-by-step explanation:
ED = EB
2x +3 = 5x -15
3+15=5x -2x
18 = 3x
18 ÷ 3 = x
x = 6
Answer:
3/8
Step-by-step explanation:
the equation is in slope intercept from (y= mx +b) mx= slope b= y intercept
5x•8y
5•8=x•y
40=x•y
5•40•8•40=
40•(5+8)
