2) 4(2x²+9x)
3) 110
4) $9.50 per pizza
5) 23
Answer is 1
Step-by-step explanation:
Answer:
55 fl oz
Step-by-step explanation:
6 cups = 48 fl oz
7/8 cups = 6 fl oz
48 +6 = 55 fl oz
For this case, what we must do is find a point that meets both inequalities.
- <em>y> -2
</em>
- <em>x + y <4
</em>
We have then:
For (0,4):
First inequation:
4> -2 (correct)
Second inequality:
0 + 4 <4 (incorrect)
For (1,4):
First inequation:
4> -2 (correct)
Second inequality:
1 + 4 <4 (incorrect)
For (-3,5):
First inequation:
5> -2 (correct)
Second inequality:
-3 + 5 <4 (correct)
Point (-3,5) is system solution
For (-2,-3):
First inequation:
-3> -2 (incorrect)
Answer:
Point (-3.5) is system solution
