Answer:
D) 9
Step-by-step explanation:
7 x 2 - 4 - 9x
14 - 4 - 9x
10 - 9x
You could easily see at first that the coefficient of x is 9 because the coefficient is the number that is before the variable, but you can also do the whole process.

Answer:
the projectile reached a maximum height of 27.6 meters in 2.4 seconds and it took 5.0 seconds for it to hit the ground
Step-by-step explanation:
to find the vertex you can find the axis of symmetry first
that equation is -b/2a
-19/-8 = 2.375
then you take this and plug it in
-4(2.375)^2 + 19*2.375 + 5
that gives you 27.5625
then you have to find when it hits the ground
you can factor to find this out
-4t^2 + 19t + 5
4t^2 - 19t - 5
4t^2 + t - 20t - 5
t(4t + 1) -5(4t +1)
(t - 5)(4t + 1)
t = {5, -1/4}
we can only take positive time so it took 5 seconds
the answer is the second one

Since their both negatives, February should be the colder tempuerter.
Answer:
The function show the value of the machinery after "t" years.
So After "4" years... Input "t" as 4 to get its value
f(t) = 12,500 - 1,600(4)
=$6,100
