The minimum cost is the y-coordinate of the vertex of the parabola represented by the equation. The x-coordinate is the number of bats.
60 bats should be produced every day to keep costs at a minimum.
Answer:
From what I understand the answer is B
Step-by-step explanation:
calculate the difference between the averages that we're dated from each month them look between your answers and from there calculate till you can an answer that fits for each one. The correct one being B
x is the average yearly temperature so another way to work this out as add all of the averages up and then work through by diving each average by twelve them look at the difference between the two
That asserts the equality of two expressions, which are connected by the equals sign "=". The word.
Answer:
10.) y = -5x + 7
12.) y = 3/2x - 8
Step-by-step explanation: Since you have to create a new line that us parallel, the slopes will be equivalent. So the mx value will not change. Now we can plug in the coordinates to find the value of b.
10.)
2 = -5(1) + b.
2 = -5 +b
b = 7
therefore...
y = -5x + 7
12.)
2(-5) = 3(2) + b
-10 = 6 + b
b = -16
therefore...
2y = 3x - 16
simplified:
y = 3/2x - 8
Answer:
3
Step-by-step explanation:
f(x) = 2x-5
substitute 4 in for x
f(4) = 2*4 -5
f(4) = 8-5
f(4) =3
