The given function is linear and slope intercept form.

To identify the function.

<h3>What is function?</h3>

A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

Given that:

The given function is

y=1/2x+6

Put this equation into a graphing calculator and you will find that each y value will be 1/2 the x value plus 6

The y-intercept simply means the value of y when x=0.

The slope is 1/2 and the y-intercept is 6.

So, the given function is linear and slope intercept form.

GUYS I NEED HELP ASAP
vovangra [49]

Answer:

A=2400ft

Step-by-step explanation:

A rectangle is a closed planer quadrilateral with four  right angles and its opposite sides are the same length. The fence around it including the gates is 200 feet long, so basically they are providing the perimeter of the rectangle. The perimeter of a rectangle is equal to the sum of all its sides. Hence:

Perimeter=w+h+w+h=2w+2h\\\\Where:\\\\w=Width\\h=Height

The ectangular playground is 40 feet wide, so:

w=40ft

Therefore:

Perimeter=2w+2h\\\\200=2(40)+2h\\\\200=80+2h

Solving for h:

2h=200-80\\\\2h=120\\\\h=\frac{120}{2} \\\\h=60ft

The area of a rectangle is equal to the product of two of its contiguous sides, hence:

A=wh\\\\A=(40)(60)=2400ft

I attached you a picture of the rectangle
