Which of the following could be a function with zeroes of -3 and 2?
1 answer:
A function with zeros -3 and 2 could be:
(x + 3)(x - 2) or x² + x - 6
Keep in mind that there are an unlimited number of functions that have these zeros, such as:
2(x + 3)(x - 2) or 2x² + 2x - 12
(x + 3)(x - 2)(x + 5) or x³ + 6x² - x - 30
Generally, the function just has to include the factors (x + 3) and (x - 2) to have the zeros -3 and 2.

Start by subtracting 2 from both side which gives you [-3x<9] then divide by -3 which gets you [x<-3] so the answer is B

45% of what number is 27
0.45x = 27
x = 27 / 0.45
x = 60 <== 45% of 60 = 27
It's the first one.
If you work backwords, I'd say it's easier. 3y swuared is 9y2, and 11 squared is 121. Then just keep the sign the same
