7. a rectangular play area is to be bounded by 120 m of fencing.
determine the maximum area and the dimensions of this rectangle.

31×29m

Step-by-step explanation:

120÷4=30

Each side would be 30 but since it must be a rectangle make 2 sides 29 and the other 2 31. making it the maximum dimensions possible.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
