Ou have the following 3 equations: 6x + 3y + z = 22
x + 4y – 2z = 12
4x – y - 5z = 10
Write these equations on the form Ax = d.

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
