Answer:
3x
Step-by-step explanation:
F(x)=x^3+x^2-9x-9
x^2(x+1)-9(x+1)
=(x+1)(x^2-9)
=(x+1)(x+3)(x-3)
Hope that this helps
Answer:
Graph D
Step-by-step explanation:
Initially, Marlon was looking for his pump. Thus, no air was pumped into the balloon until he got the pump. On getting the pump, he inflated the balloon with air at a constant rate, after which he tied it with a string to prevent the air from escaping.
The analysis is that, at the time he decided to inflate the balloon till he got a pump, the volume of air in the balloon is zero with respect to time. Pumping air at a steady rate into the balloon increases the volume of air flowing into it gradually and steadily.
When the volume got to a definite amount, he stopped pumping air and tied with a string. Thus, the volume of air in the balloon remains constant.
Answer:
28 baskets
Step-by-step explanation:
The equation for a linear trend line is given by:
y = mx + b, where y and x are variables, m is the slope of the line and b is the y intercept (that is value of y when x is zero).
The equation of a line passing through two points
is:

y represent the number of baskets made and x represents the time take. Given that the line passes through the points (0, 11) and (100, 33), hence:

The number of baskets Romy would make after practicing for 80 minutes (x = 80) is:

-36 divided by 9 plus -5 minus 6 is equal to -15
