marin [14]

Answer:

Options (2), (3), (5) and (6)

Step-by-step explanation:

Let the number of bicycles = x

and the number of treadmills = y

Since, number of new bicycles must be more than \frac{1}{3} times of new treadmills,

Inequality representing the statement will be,

x > \frac{1}{3}y

Each bicycle costs $340 and each treadmill costs $670.He must spend less than $5650,

Inequality will be,

340x + 670y < 5650

And the number of bicycles and treadmills should be greater than 0.

x > 0

y > 0

Therefore, constraints for this situation are,

Option (2)

Option (3)

Option (5)

Option (6)

Anastasy [175]

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~

To solve this we will first find out what f(x) equals at the given point of 4, and than substitute that answer it for g(f(4))...

f(x) = x - 7

f(4) = 4 - 7 = -3

g(f(4)) = (x - 7)^2  >  -3^2 = 9

So...

The answer is: g(f(4)) = 9
