Answer:
12.50x less than or equal to $200
Step-by-step explanation:
The ordered pair that is the best estimate for the solution of the system of equations is (7, 1/2)
The given system of equations is:

Equate equations (1) and (2)

Solve for x in the equation above

Substitute x = 7 into equation (1)

The ordered pair that is the best estimate for the solution of the system of equations is (7, 1/2)

Answer:
D. $43.00x + $466.43 < $1,059.35
Step-by-step explanation:
He has $1,059.35.
The amount of speakers he buys is x.
Each speaker is $43.00, and he is buying one television, which is $466.43.
All of the speakers he buys and(+) the television must be less than $1,059.35 because that's all he has. It cannot be more, which is why the equation is $43.00x + $466.43 < $1,059.35.
Hope this helps!
Answer:
A. y= 2(x - 2)2 + 4
Step-by-step explanation:
vertex having an x value of 2 means the phrase in paren must be x - 2.
This eliminates B and D
vertex having a y value of 4 is of no help as the remaining two equations will result in 4 if the x term is 2
plugging in x = 3 makes y = 6 in equation A, but not in equation C where y = 10
The <span>cubic model that best fits this data is </span><span>y = 0.0000872x^3 - 0.00989x^2 + 0.403x + 1.192</span>
