List all two-element sets in p({a, b,c, d})

note: this is discrete math, p stands for power set. explain if possible.

{a,b}, {a,c} , {a,d}, {b,c}, {b,d}, {c, d}

Step-by-step explanation:

If we have P({a, b, c, d}) where P is the power set, we know that there are 6 two elements sets in P (because this is the number of combinations of two elements taken from 4 elements,

These 6 sets would be: {a,b}, {a,c} , {a,d}, {b,c}, {b,d}, {c, d}

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.
