Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -5x - 2
f(3) is x = 3
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(3) = -5(3) - 2
- Multiply: f(3) = -15 - 2
- Subtract: f(3) = -17
The number of students allowed to sit, N=4.
The total number of minutes, T=38 minutes.
Let x be the number of minutes for a student
<span>7/3+3(2/3−1/3)^2
= 7/3 + 3(1/3)^2
= 7/3 + 3(1/9)
= 7/3 +1/3
= 8/3</span>
2×-2=-4
-4 × -2 = 8
8 × -2 =-16
-16×-2 =32
32 ×-2 = -64.
therefore the answer is -2.
