Fill in the table using this function rule y=27-4x
1 answer:
Step 1: Y= 27 - 4x
To find X - intercept / zero, substitute Y = 0
0 = 27 - 4x
Step 2: 0 = 27 - 4x
Move variable to the left-hand side and change it's sign.
4x = 27
Step 3: 4x = 27
divide both sides of the equation by 4
X = 27/4
solution: X = 27/4
Alternate form: X = 6 3/4, X = 6.75

Intensity=k/(distance)² where k is a constant
8000=k/2²
8000=k/4
k=32000
If distance is 11 miles, Intensity=k/11²
=32000/121
=264.46units
≈264units
