If y is proportional to x and y = -15 when x = -20, what is the value of x when y = 12?
Alex
When y=-15, x=-20. So subtract x from y, you will get that y= 0 and x=-5. Add 12 to both and you have your answer, x=7 and y=12

Fred and Sue want to fence in a rectangular area in their yard for a vegetable garden. Suppose that they have 30 feet of fencing
larisa [96]

Answer:

a=35x−x^2

Step-by-step explanation:

Having  

70 ft of fencing with a  

width of x

feet and knowing the perimeter of a rectangle is  

p=2w+2l

we can state the length of the garden as:

70=2x+2l

and solving for  l

we know the length with be:

2l=70−2x or l=35−x  

And then knowing the formula for the area of a rectangle is  

a=w⋅l

we can write the equation as:

a=x⋅(35−x)a=35x−x^2
