Margaret and Kevin each improved their yards by planting rose bushes and daylilies. They bought their supplies from the same sto
1 answer:
The cost of one rose bush is $2 and one day lily is $10.
Step-by-step explanation:
Let,
Cost of one rose bush = x
Cost of one day lily = y
According to given statement;
7x+6y=74 Eqn 1
7x+y=24 Eqn 2
Subtracting Eqn 2 from Eqn 1
Dividing both sides by 5
Putting y=10 in Eqn 1
Dividing both sides by 7
The cost of one rose bush is $2 and one day lily is $10.

Answer:
Step-by-step explanation:
Let
x----> the length of the rectangular garden
y---> the width of the rectangular garden
we know that
The perimeter of the rectangle is equal to
we have
so
simplify
------> equation A
Remember that the area of rectangle is equal to
----> equation B
substitute equation A in equation B
----> this is a vertical parabola open downward
The vertex is a maximum
The y-coordinate of the vertex is the maximum area
The x-coordinate of the vertex is the length side of the rectangle that maximize the area
using a graphing tool
The vertex is the point
see the attached figure
so
Find the value of y
The garden is a square
the area is equal to
----> is equal to the y-coordinate of the vertex is correct
