<u>(2) Graph 2</u>
Step-by-step explanation:
<u>Question 40</u>
- | 2x + 3 | > 7
- It means the absolute value has to be greater than 7
- At x = -5 and x = 2, the absolute value is 7
- So, the numbers between them won't be included
- The points have an open dot
- x < -5 and x > 2
- <u>(2) Graph 2</u>
X+y=-4
2x-y=1
—————
3x=-3
X=-1
Now replace x in one of the equations to find y
Y=2(-1)-1= -3
Final answer =
X= -1
Y= -3
