A at duck is resting on the surface of a lake, an altitude of 0 feet above sea level. It dives to
-5 feet to eat. Then it returns to the surface.
Which of these occurred between the time the
duck ate and the time it returned to the surface?
A. The duck's altitude increased by 5 feet.
B.
The duck's altitude decreased by 5 feet.
C. The duck's altitude increased by 10 feet.
D. The duck's altitude remained the same.

B

Step-by-step explanation: cause the duck went down so the altitude decreased by 5 not increased which makes B correct.

B

Step-by-step explanation:

if the duck started at 0 its at ground level, it states that the duck dove, so minus 5 or -5, decreased means take away. Thus the answer is B. Sorry if I didn’t word this to help explain.

i think the answer is d im not sure

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
