Answer:
(attached file #2)
Step-by-step explanation:
let's change the variable n to a variable x (it can be x and y):
x ≥ -8
go to the X-axis which is the line going horizontal, just as the first picture attached!
2. Now go to the -8 on that line and draw a straight bold line going up (vertical)
and there you have the answer to the question.
if the question was with this symbol: < or > then the line would be dashed instead of being a bold solid straight line!
Hope this helps,
Lucas
Answer:
A
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 3x² + 4x - 6 - (6x³ - 5x² - 2) ← distribute parenthesis by - 1
= 3x² + 4x - 6 - 6x³ + 5x² + 2 ← collect like terms
= - 6x³ + 8x² + 4x - 4
The answer is B. First turn all the results from the spelling competition into fractions (or ratios).
Megan: 45/50 = 9/10
Justin: 27/30 = 9/10
Fernando: 84/120 = 7/10
Then, use this information to find which answer is correct.
Have a nice day! :)
50 is not a perfect square because it does not have a perfect square root where as 49 is 7, 121 is 11, and 1 is 1
