Answer:
Assuming the same pace was kept, it would take 9.6 minutes.
Step-by-step explanation:
We can find this by setting up a proportion and then cross multiplying.
5 baskets/6 mins = 8 baskets/x mins
5 * x = 6 * 8
5x = 48
x = 9.6
It looks like ∆ is defined as
<em>a</em> ∆ <em>b</em> = (<em>a</em> + <em>b</em>)² + 5
If that's the case, then
1 ∆ (-4) = (1 + (-4))² + 5 = (-3)² + 5 = 9 + 5 = 14
You have to use the y=mx+b formula to find the equation
