A submarine started at an elevation of -1250 feet, or 1250 feet below sea level, and it submerged another 25 feet per second. It continued to submerged for 10 seconds. What was it's new elevation?!

-1500ft

Step-by-step explanation:

Fx = - 1250 + (-25)t

= - 1250 + (-25)10

= - 1250 - 250

= - 1500

Equation models the scenario.

Hans will plant 16 snapdragons.

Step-by-step explanation:

From the given table , it can be seen that the number of snapdragons and daisies are inversely proportional because as number of snapdragons is increasing the number of daisies is decreasing.

Also, there is constant change in y with respect to change in  x.

For every one unit increase in snapdragons (x), there is one unit decrease in number of daises (y) .

Slope of function =   (1)

Thus, the equation models the scenario must be linear.

The linear equation is given by :-

, where a= slope (rate of change )

b= y-intercept or initial value for y.

Substitute a=-1  (from (1)), x=11 and y = 34 (from table) , we get

Put a= -1 and b= 45 in (1)

⇒ Equation models the scenario:

            (2)

Put y= 29  in (2), we get

Hence, he will plant 16 snapdragons.
