Answer:
9.8x + 1.1y + 9.9z
Step-by-step explanation:


⇒ 5.5x + 6.2y + 4.3x + 8.3z + 1.6z - 5.1y
⇒ 9.8x + 1.1y + 9.9z
Using the graph that is included, look at the points given. For example (30, 3). There would be 30 vegetarian dishes and 3 steak dinners for a total of 33 meals. If that is plugged into the cost equation 20(30)+3(30) it would equal $690. The next point (33, 1) would cost 20(33) + 30(1) = $690 and but gives 34 meals. However, 34 vegetarian meals would only cost 20(34)=$680 and have 34 meals.
If both types of meals need to be purchased, 33 vegetarians and 1 steak. If only vegetarians are purchased, the cost is cheaper by $10.
Answer:
(-1/2, 23/4)
Step-by-step explanation:
Vertex of graph: -b/2a
b=1
a=1
Therefore, -1/2 is your x-value
Solve for y: y=1/4-1/2+6
y=5 3/4 or 23/4
Therefore your vertex is: (-1/2, 23/4)
