Yes this is linear due to the fact that they are combining the letters x and y because they are a linear pit

Answer:
10 hours
Step-by-step explanation:
Amount paid= material fee + ($8)(number of hours worked)
Let the number of hours the plumber worked be t.
$107= $27 +$8t
107 -27= 8t
80= 8t
8t= 80
Divide both sides by 8:
t= 80 ÷8
t= 10
Thus, the plumber worked for 10 hours.
Given:
Oil flow: n(t) = 7t where t is time and n = how far the oil is spreading
Area of the circular pattern the oil is forming:
A(n) = πn²
<span>Part A: Find the area of the circle of spilled oil as a function of time, or A[n(t)]
A[n(t)] = </span>π (7t)² = π * 49 * t²
<span>How large is the area of spilled oil after 8 minutes?
n(t) = 7t </span>→ 7 * 8 = 56
A(56) = 3.14 * 56² = 9,847.04 square units
or
A[n(t)] = π (7t)²
A[n(8)] = 3.14 * (7*8)² = 3.14 * 3,136 = 9,847.04 square units
