Sammys mother is 2 years more than 3 times as old as sammy. their combinied age is 42. how old are sammys mother and sammy

In which direction does the left side of the graph of this function point? a(x) = 3x - x2 + 4x - 2

Multiply and simplify. (x - 4) (x^2 – 5x – 6) i will mark brainliest if your answer is right. show how you got the answer. if your answer is correct but does not show how you got the answer you will not be marked brainliest.

Find the power set of each of these sets, where a and b are distinct elements. a) {a} b) {a, b} c) {1, 2, 3, 4} show steps
