Answer:
x=-6
y=-11
Step-by-step explanation:
x-y=-5
7x+3y=-75
x=5+y plug that in to the second equation
7(5+y)+3y=-75
35+7y+3y=-75
10y=-75-35
10y=-110
y=-11
plug y into first equation
x+11=5
x=5-11
x=-6
Answer:
c is the answer
Step-by-step explanation:
Answer:
He should serve 2 chocolate bars and 2 granola bars
Step-by-step explanation:
Let's define
x: amount of chocolate bar
y: amount of granola bar
We are asked to solve the following optimization problem:
maximize 7*x + 2*y
subject to
50*x + 25*y ≤ 150
5*x + 15*y ≥ 40
x ≥ 0
y ≥ 0
In the figure attached, the feasible region is shown. The solution is one of the vertex
vertex objective function
(0, 2.667) 7*0 + 2*2.667 = 5.334
(2, 2) 7*2 + 2*2 = 18
(0, 6) 7*0 + 2*6 = 12
The exact answer is 12 root 2, but you can also say approximately 17.
I got this by finding the square root of 369, and then 81. After finding these values, you get the equation...
a^2 + 9^2 = 369
a^2 + 81 = 369
a^2 = 288
And then I just found the square root of 288
