Ok so I created a equation to see how many seconds can you go to get to 180. The equation is 0.4x = 180 and I got 450. Now I concluded from this result the inequality is A, x < 450 because unless you want your submarine to crash in the seafloor you should probably stop before 450 seconds.

Answer:
280 more miles.
Step-by-step explanation:
The question stem "how many more" usually means your going to need to subtract somewhere in this problem.
If your destination is 400 miles away, and you have already driven 120 miles, all we need to do it subtract 120 from 400.

Answer:
k = 13
smallest zero = -6
Step-by-step explanation:
f(x) is basically the function of x.
x could be any integer. f(x) is the solution of the function of x.
f(x) is defined as x² + 3x - 10
f(x) = x² + 3x - 10
Now, f(x+5) = x² + kx + 30
This statement here says that if the value of x is x+5, then the answer would be x² + kx + 30.
f(x) = x² + 3x - 10
f(x+5) = (x+5)² + 3(x+5) - 10
f(x+5) = x² + 10x + 25 + 3x + 15 - 10
f(x+5) = x² + 13x + 40 - 10
f(x+5) = x² + 13x + 30
x² + 13x + 30 = x² + kx + 30
hence, k = 13
Smallest zero = The smallest x value.
f(x+5) = x² + 13x + 30
Let's take f(x+5) = 0
x² + 13x + 30 = 0
which two numbers products give us 30 and add up to 13?
== 6 and 5
(x+6)(x+5) = 0
x+6 = 0
x = -6
x+5 = 0
x = -5
The two solutions are -6 and -5
The smallest out of these two is -6.
