For the set B= { 3, 5, 7, ,9 , 12, 17, } determine n(B)
n is asking for the count of numbers in the set.
Set B has 6 numbers.
n(B) = 6
I don't understand your question but:
(x + 5)(x + 2)
= x^2 + 5x + 2x + 10
= x^2 + 7x + 10
Answer:
i'm pretty sure its B but it would be helpful if i could see a graph
Step-by-step explanation:
The slope is negative and is -16 / 8 = -2
The y intercept is at y = 16
General form is y = mx + c
m = -2 and c = 16 so we have :-
y = -2x + 16 Answer
It looks like you intend
x¹⁹ -2x¹⁸ +7x¹⁷ -12x¹⁶ +6x¹⁵ = 0
x¹⁵(x -1)²(x² +6) = 0
x = 0, 1, ±(√6)i . . . . . . . selection D is appropriate
