Answer:
x = 1 y = -4
Step-by-step explanation:
- Plug the value of y into the other equation.
x + 3y = -11
x + 3(-4x) = -11
x - 12x = -11
-11x = -11
x = 1
- Now substitute the value of x into any equation.
y = -4x
y = -4(1)
y = -4

Answer:
b. S = 405, D = 0
Step-by-step explanation:
We have been given that profit for a particular product is calculated using the linear equation: 
. We are asked to choose the combinations of S and D that would yield a maximum profit.
To solve our given problem, we will substitute given values of S and D in the profit function one by one.
a. S = 0, D = 0
b. S = 405, D = 0
c. S = 0, D = 299
d. S = 182, D = 145
Since the combination S = 405, D = 0 gives the maximum profit ($8100), therefore, option 'b' is the correct choice.
Answer: 3
Step-by-step explanation: Half of 5 is 2.5 so 3 2/5 will be estimated to a 3 1/2 and 5/8 is very close to 4 which is half of 8. so 5/8 will be estimated to 1/2! Both of them subtracted is gonna be 3 because 1/2 - 1/2 is 0!
