Which of the following is an example of mutualism? a group of piranhas work together to attack a large animal. a mosquito feeds off the blood of another animal and leaves an itchy bump. barnacles attach themselves to the bottom of a boat for transportation. a sea sponge attached to a crab the crab hide from predators and gains transportation for itself.

A seas sponge attached to a crab.

Step-by-step explanation:

Mutualism is when both organisms benefit. In this case the sponge gets protection and the crab does as well.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
