The formula for conditional probablity states that
Since we know both numerator and denominator, we only need to plug in the values:
Step-by-step explanation:
(2(x+y)÷(x+y)(x-y) )×(x+y÷(x^2+2×x×2y+2y^2)
2÷x^2+2y^2
P= 3
Q= -14
R= -5
Step-by-step explanation:
Just solve the equation on the right side, you'll get:
=3x^2 -15x +x -5
=3x^2 -14x -5
Now compare it to the equation on the left side,
The coefficient of x^2 on the left is "p", on the right that we just solved is 3.
Same for "q" which is the coefficient on the left, on the right it's -14.
And for "r" it's -5 from the equation on the right.
Step-by-step explanation:
y = 2x + 3
When x = 2
y = 2.2 + 3
y = 4 + 3
y = 7
When x = 0
y = 2.0 + 3
y = 0 + 3
y = 3
When x = -2
y = 2.(-2) + 3
y = -4 + 3
y = -1
When x = -4
y = 2.(-4) + 3
y = -8 + 3
y = -5
When x = -7
y = 2.(-7) + 3
y = -14 + 3
y = -9
