Answer:
y < -3 and
2x - 3y ≥ -15
Step-by-step explanation:
y < -3
Take any two points on the bold line
(0 , -5) and (-3 , -7)
Now find the slope for this line and then the equation of the line
Slope =
Slope, point equation,
y - y1 = m(x -x1)
Take any point from the shaded region and plugin the LHS of the equation.
(-6 , -5)
LHS = 2x - 3y
= 2*(-6) -3*(-5)
= -12 + 15
= 3 which is ≥ -15
2x - 3y ≥ -15
Answer:
The solved expression is and
Therefore
Step-by-step explanation:
Given quadratic equation is
To solve the given equation by using completing the square :
Rewritting the above equation as below :
( it is of the form of heere a=x and b=3 )
Taking square root on both sides we get
Therefore and
Answer:
Step-by-step explanation:
Given that if an odd number comes up, you lose.
i.e.
If you get 2 or 4 you roll again
Thus rolling again prob =
After rolling II time, if get 6, win otherwise lose.
Thus winning amounts A canbe
0 36 60
This is a genuine pdf since prob >0 and total prob = 1.
b)Expected gain = sum of gain * prob =
Thus I would be willing to pay an amount atmost 12 dollars.
7x+(-14)
-14+7x
These two equations are both equal to 7x-14.
