Answer:
x - intercepts are (-7,0) and (-2,0)
A is the correct option.
Step-by-step explanation:
We have been given the equation of the parabola 
For x- intercept, y = 0
We can split the middle term as 9x = 7x +2x
Now take GCF
Factored out the common term
Apply the zero product property
Solve for x
Hence, x - intercepts are (-7,0) and (-2,0)
A is the correct option.
Answer:
300
Step-by-step explanation:
3 would be extremely low
30 would be low
300 would be about right
3,000 lets not talk about this
Hope this helps
Answer:
-12
Step-by-step explanation:
The slope of a line is just the difference of y-values divided by the difference of x-values
1 km = 1,000 m
43 km = 43,000 m
4,300 m < 43,000 m
so 4,300 m < 43 km
f(x) = x2 - 2x + 2
g(x) = x - 3
(f • g)(x) = (x2 - 2x + 2)(x - 3)
(f • g)(x) = x2(x - 3) - 2x(x - 3) + 2(x - 3)
(f • g)(x) = x3 - 3x2 - 2x2 + 6x + 2x - 6
(f • g)(x) = x3 - 5x2 + 8x - 6
The answer is B.
