ANSWER
C. 38.83 miles per hour.
EXPLANATION
It was given that, the fuel economy of a car, measured in miles per gallon, is modeled by the function
We rewrite the function in the vertex form by completing the square.
Or
The vertex of this function is
Hence the maximum fuel economy is 25.57 gallons and this occurred at an average speed of 38.83.
The correct answer is C
Answer:
3rd Matrix
Step-by-step explanation:
When you start putting the coefficients in as the matrix, you see that -9 has to be the 1st number, so that eliminates choice B and choice D as answers. You are left with choices A and C. C is the correct choice because when you plug in the second equation, your coefficient is -5, not 0.
Answer:
Condition 1:
four times the sum of X and Y = 4(X + Y)
Condition 2:
the sum of four times X and Y= 4X + Y
In condition 1, both the variables are first added and then multiplied by four. This can be simplified as:
4X +4Y
I condition 2, only the variable X is multiplied with 4 and then added to Y.
With positive integers, condition 1 will always give a greater value.
With negative integers, condition 2 will have greater value.
