Answer:
Step-by-step explanation:
Bag A:
White = 3
Total = 3 White + 2 Red = 5
Prob (white marble from A) = 
Bag B:
White = 6
Total = 6 White + 3 Red = 9
Prob (white marble from B) = 
Prob (white from Bag A and white from Bag B)
= Prob (white marble from A) x Prob (white marble from B)
= x
=
// Solve equation [1] for the variable x
[1] x = 2y - 1
// Plug this in for variable x in equation [2]
[2] 2•(2y-1) - 5y = -3
[2] - y = -1
// Solve equation [2] for the variable y
[2] y = 1
// By now we know this much :
x = 2y-1
y = 1
// Use the y value to solve for x
x = 2(1)-1 = 1
Answer:
6
Step-by-step explanation:
Answer:
One Solution ; x=4.5
y=-1.5
Step-by-step explanation:
Line A: 2x+2y=8
÷<u>2</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>
x+y=4
Line B: x+y=3 -----> y=x-3
x+(x-3)=4
2x-3=4
2x=7
x=4.5
y=-1.5
Answer:
6-3/0-(-4)
=3/4
Step-by-step explanation:
Given two points of a line to find the slope, we use the formula.y2-y1/x2-x1 hence the answer above. Our xs are x2=0 x=-4 y2=6 y1=3
