I believe the percentage of this is 50%. Half the numbers are even, and half are odd. Your fraction is
\frac{6}{12}
Simplified, that's a 50% probability.

5x + 2y = -3<br>3x + 3y = 9​
Karolina [17]

Answer:

Step-by-step explanation:

5x + 2y = -3

3x + 3y = 9

15x + 6y = -9

-15x - 15y = -45

-9y = -54

y = 6

5x + 2(6) = -3

5x + 12 = -3

5x = -15

x = -3

(-3, 6)

Solve x^2 + x - 12 = 0
bogdanovich [222]

Answer:

x₁ = -4

x₂ = 3

Step-by-step explanation:

x²+ x + 12 = 0

x = {-1±√((1²)-(4*1*-12))} / (2*1)

x = {-1±√(1+48)} / 2

x = {-1±√49} / 2

x = {-1±7} / 2

x₁ = {-1-7} / 2 = -8/2 = -4

x₂ = {-1+7} / 2 = 6/2 = 3

Check:

x₁

-4² + (-4) - 12 = 0

16 - 4 - 12 = 0

x₂

3² + 3 - 12 = 0

9 + 3 - 12 = 0
