Answer:
The charges will be the same after 4 hours.
Step-by-step explanation:
Total Amount = y
Number of hours = x for x > 2
Garage A: y = $7.00 + (x - 2)*3
Garage B: y = 3.25*x
Part 3: What is the cost to be equal?
3.25x = 7 + 3(x - 2) Remove the brackets
3.25x = 7 + 3x - 6 Collect terms on the right
3.25x = 3x + 1 Subtract 3x from both sides.
3.25x - 3x = 3x - 3x + 1 Combine
0.25x = 1 Divide by 0.25
0.25 x/0.25 = 1 / 0.25
x = 4 hours.
Answer:
2, 3/4 and 1
Step-by-step explanation:
Sin x = 7/12
x = arcsin (7/12) = 35.69°
Answer:
done
Step-by-step explanation:
I have installed it
x^2 + 6x + 7 = (x + 3)^2 - 2
So the axis of symmetry is x = -3
