A small submarine starts at –1,260 feet in relation to sea level. Then it descends 5 feet per minute for 12 minutes. What integer represents the rate of motion of the submarine?

–
feet per minute

Okay so our starting point is - 1,260 feet

Now it is descending (-) 5 ft per minute for 12 minutes

So we multiply -5 (negative because it is descending) by 12

-5 x 12 = -60

So now we add -60 to -1,260

This would be -1,320

So the submarine's new position in relation to the sea level is -1,320

Hope this helped. Have a great day!

that would be -1260 + 12(-5) = -1260 - 60 = -1320 feet

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
