The start of the hike, a hiker was at -50 below sea level and climbs a rate of 15 feet per minute Which of these inequalities describes this situation when the hiker's elevation was higher than 5 feet above sea level where t represents the number of minutes after the start of the hike?
A. -50 + 15t < 5
B. -50 + 15t > 5
C. 15 - 50t < 5
D. 15 + 50t > 5

B. -50+15t>5

Step-by-step explanation:

Because the hiker climbs at a rate of 15 feet per minute, the hiker will climb 15t feet in t minutes. Therefore, -50 + 15t would represent where the hiker would be after t minutes. According to the problem, -50 + 15t is greater than 5

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
