Answer:
x+y=200
xy=9,600
Step-by-step explanation:
The diagram shows rectangular parking lot with sides of x feet and y feet.
1. The area of the rectangle is given by
A=Length \times Width
A = xy -------------------------(1)
We are given that the area of the parking lot is 9,600\ ft^2, then
eq(1) becomes
9,600 = xy ---------------------(2)
2. A parking lot has a 200ft fence built along two adjacent sides of lengths x and y, then
Then the perimeter of the two adjacent sides
x+y=200
---------------------------------(3)
Thus ,The system of two equations are
x+y=200
xy=9,600
Answer:
C) infinitely many solutions
Step-by-step explanation:
y= 3x-4
-3y= -9x +12
-3(3x-4 ) = -9x +12
-9x + 12 = -9x + 12
C) infinitely many solutions
760 total students....4 out of 7 graduated...3 out of 7 didn't
so 4/7(760) = 3040/7 = 434.28 <== so approx. 434 will graduate
and 3/7(760) = 2280/7 = 325.7...and approx. 326 won't graduate
I got the answer b hope it helps
