Answer:
(4,2)
Step-by-step explanation:
-3x+5y=-2
3x+7y=26
I will add the two equations to eliminate x
-3x+5y=-2
3x+7y=26
---------------------
0x + 12y = 24
Divide by 12
12y/12 = 24/12
y =2
Now find x
3x+7y =26
3x+7*2 =26
3x+14= 26
Subtract 14 from each side
3x+14-14 =26-14
3x= 12
Divide by 3
3x/3 =12/3
x=4
The system of inequalities that represents the possible length in meters, l and the possible width in meters, w is given as l + w > 31 and w ≥ l - 10
The formula for calculating the perimeter of the rectangular ool is expressed as:
P = 2(l + w)
- l is the length of the ool
- w is the width of the ool
If the perimeter of a rectangular ool is more than 62 meters, hence;
If the width is <u>at least 10 meters less than the length,</u> this is expressed as:
Hence the system of inequalities that represents the possible length in meters, l, and the possible width in meters, w is given as l + w > 31 and w ≥ l - 10
