Answer:
(x + 15) / 2
Step-by-step explanation:
Distance = rate × time
d = (x² – 225) / (2x − 30)
d = (x – 15) (x + 15) / (2 (x – 15))
d = (x + 15) / 2
The total hours joe spent watching TV each day for two weeks is 12 1/2 hours
<h3>Total hours spent watching TV</h3>
Total hours spent watching TV for two weeks = Number of hours × days
= (0 × 1) + (1/4 × 1) + (1/2 × 1) + (3/4 × 3) + (1 × 3) + (1 1/4 × 4) + (1 1/2 × 1)
= 0 + 1/4 + 1/2 + 9/4 + 3 + 5 + 3/2
= 8 + (1+2+9+6) / 4
= 8 + 18/4
= 8 + 4 2/4
= 8 + 4 1/2
= 12 1/2 hours

Slope of the line passing through these points is -5/6.
Equation of the line is 6y+5x+13=0.
So any point not satisfying this equation could be an answer such as (0,0)
5/3 % * x = 4.75
5/300 x =4.75
x = 4.75 * 300/5
x=4.75 * 60
x=285
