A turtle is on a rock that is 1.1 feet above sea level. The turtle dives under water. The turtle's total change in altitude during the dive was 5.4 feet. Which equation can be used to determine the depth to which the turtle dove?

-4.3 feet

or -5.4 ft + 1.1 ft

Step-by-step explanation:

How I solved this is by reading this carefully , It said 1.1 feet above water so positive and -5.4 feet dive down so that is negative correct? so you would subtract   - 5.4 + 1.1 which is -4.3

Am I correct?

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
