HELP (BRAINIEST PROMISED) A dolphin was swimming 6 feet below sea level. The number line shows the location of the dolphin. It then swam up 4 feet. Describe how to use the number line to find the new location of the dolphin.

A.

On the number line, move 4 units to the left. End at 2. The dolphin was 2 feet above sea level.

B.

On the number line, move 4 units to the right. End at −2. The dolphin was 2 feet below sea level.

C.

On the number line, move 4 units to the right. End at 10. The dolphin was 10 feet above sea level.

D.

On the number line, move 4 units to the left. End at –10. The dolphin was 10 feet below sea level.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,

mrb

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .

what are your
