<h3>
Answer: (1,3)</h3>
=====================================================
Explanation:
Note that the two shaded regions overlap to form the darker shaded region. The point (1,1) is only in the green region, but not in the blue region. It needs to be in both regions for it to be a solution to the system. In contrast, the point (1,3) is on the boundary of the blue region and in the green region as well. It's a solution point because of this.
Points on the boundary are included because of the "or equal to" as part of the inequality sign. Hence the solid boundary lines rather than dashed boundary lines.
The solution (1,3) means that x = 1 and y = 3 pair up together. It says that Cody can buy x = 1 hotdog and y = 3 packs of peanuts so that he has at least 4 snacks, and he stays within the $7 budget.
Going back to (x,y) = (1,1) for a moment, this isn't a solution because x+y = 1+1 = 2 is not 4 or larger. In other words, he only buys 2 snacks here instead of 4 or more.
Answer:
3 13/16
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
3/8=x/24 (cross multiplication)
3*24=8x (we don't need to multiply 3 with 24 bc we will divide both sides by 8 so it will be easier to find the final value)
x=9
Answer:
254.34
Step-by-step explanation:
You first have to know the formula which is
You multiply 9 by 9 which gives you 81.
pi equals 3.14
so 3.14 × 81 = 254.34
Answer:
9
Step-by-step explanation:
- 36 = 5x
- 36 = 5x
-5x = 36
- 45 = 36
+ 45 + 45
-----------------------
81 = 81 ✅
- 36 = 5(9)
81 - 36 = 45 ✅
