Answer:
9,540,000 square miles
= 17,210,000
B.(0, 2)
C.(5, 6). D.(6,-3)
E. (11, 12)
The two ordered pairs would represent points on a graph of 5x + 6y = 12 is (0, 2) and (6, -3)
From the question, we have the following parameters that can be used in our computation:
5x + 6y = 12
Using the ordered pair (0, 2), we have
5 * 0 + 6 * 2 = 12
12 = 12
Using the ordered pair (6, -3), we have
5 * 6 + 6 * -3 = 12
12 = 12
Hence, the ordered pairs on the point on a graph are (0, 2) and (6, -3)

B) Systematic random sample
C) Voluntary response sample
D) Convenience sample
Step-by-step explanation:
The answer is A. The answer is A because the teacher put names in a hat without looking. That narrows down the answer to A and B. Since he didn't do it in a special scientific way the answer is A
Equation D: y = 7x + 2
Which of the following best describes the number of solutions to the given set of equations? (1 point)
One solution
Two solutions
Many solutions
No solution
Two linear equations y = 7x + 12 and y = 7x + 2 don't have any solution.
A linear equation is an equation where the variable has the highest power of one. A linear equation could have more than one variable. However, the highest power of the variable is one.
Given, 1st equation is y = 7x + 12
⇒ - 7x + y = 12
Therefore, a₁ = -7, b₁ = 1, and c₁ = 12.
The second equation is y = 7x + 2
⇒ - 7x + y = 2
Therefore, a₂ = -7, b₂ = 1, and c₂ = 2.
We know, two linear equations can't have any solution if a₁/a₂ = b₁/b₂ ≠ c₁/c₂.
Therefore, -7/ -7 = 1/1 ≠ 12/2.
Hence, these two linear equations have no solution.

#SPJ2
There is no solution because 12 and 2 are totally different numbers, it doesn't work, because both x's have a 7(7x).
there are no solutions.
For this case, the first thing we must do is define variables:
x: ounces of oregano
y: ounces of garlic powder
We write the function to find the total cost of the mixture.
We have then:
We substitute the following values to find the total cost:
Four ounces of oregano:
and 2 ounces of garlic powder:
Substituting we have:
Answer:
The total cost of the mixture is given by:
c (4, 2) = 22 $
