Graph of Parallel lines shows a system of equations with no solutions
Step-by-step explanation:
Consider a set of equations

If we solve this both equations using any one of the solving method, (Substitution method) then we will get

substituting the following x in 2nd equation (21x + 6y = 24) We get

Put y= -2 in x equation

Comparing these (x,y) values we can understand that they never meet at a point
Answer:
D
Step-by-step explanation:
We will turn the left side into the right side.

Use the identity:



Now use the identity
solved for sin^2 x and for cos^2 x.




Maximum profit due to the feasibility graph....we take where the two lines cross...(6,5). These figures are substituted into the equation and the result is the max profit...
p = 3x + 2y
p = 3(6) + 2(5)
p = 18 + 10
p = 28

Multiplication is commutative so can be multiplied anyway
(2.0× 109)(3.02×104)
2.0 can be written as ( 20÷ 10) and 3.02 can be written as (302÷ 100)
(2× 109){(3.02÷ 100)× 104]
(218)(7852÷ 25)
