Answer:
1/3
Step-by-step explanation:
If you add all the n's, it would make 3n=1. Divide both sides by 3 and get n=1/3
9x²- 25
3x(3x) = 9x²
3x(5) = 15x
-5(3x) = -15x
-5(5) = -25
9x² + 15x - 15x - 25
9x² - 25 is your answer
hope this helps
Are you sure your in high school, also it's answer #3.
Answer:

when x is 2, y is -4

None of the objectives is right
Slope intercept is y=Mx+b where m is always the slope and b is always your y intercept. The point slope fo is y-y^1=m(x-x^1) where x1 and y1 are a known point and m is the still the slope. X and y is another point on the linear equation
