Answer:
Point B
Step-by-step explanation:
Lines given:
- y= 2/5x - 1/2
- y= -1/3x +2/3
x coordinate of intersection of given lines is:
- 2/5x - 1/2= -1/3x+2/3
- 2/5x+1/3x= 2/3 +1/2
- 6/15x+5/15x= 4/6+3/6
- 11/15x=7/6
- x= 7*15/11*6
- x= 35/22
For this value of x, the value of y is:
- y= 2/5*35/22 - 1/2
- y=14/22- 1/2
- y= 3/22
As per graph point (35/22, 3/22) is point B
Xy - x - y + 1
explanation: distribute (x-1)(y-1) —> x(y-1) - 1 (y-1) —> xy - x - 1(y-1) —> xy - x - y + 1
I don't understand your question
<span>length = 7x
</span><span>width = 2x
2(7x + 2x) = 72
7x + 2x = 72/2
9x = 36
x = 36/9
x = 4
</span>
width = 2x = 2 * 4 = 8 units<span>
</span>
