Question

7.5.3 practice 1
type your answers in the boxes below.
a. a fish starts at -8 m and changes 14 m. \boxed{} m
b. a whale starts at -8 m and changes -14 m. \boxed{} m
c. a diver starts at 9 m and changes -14 m. \boxed{} m
d. a butterfly starts at 15 m and changes 12 m. \boxed{} m
e. a bird starts at 15 m and changes -12 m. \boxed{} m

Explanation:

Step1: Solve for A

The fish starts at -8 m and changes by 14 m. We use the formula: final position = initial position + change. So, $-8 + 14 = 6$.

Step2: Solve for B

The whale starts at -8 m and changes by -14 m. Using the formula: $-8 + (-14) = -22$.

Step3: Solve for C

The diver starts at 9 m and changes by -14 m. Using the formula: $9 + (-14) = -5$.

Step4: Solve for D

The butterfly starts at 15 m and changes by 12 m. Using the formula: $15 + 12 = 27$.

Step5: Solve for E

The bird starts at 15 m and changes by -12 m. Using the formula: $15 + (-12) = 3$.

Answer:

A. 6
B. -22
C. -5
D. 27
E. 3
