Answer:
x =8
Step-by-step explanation:
To answer this question you must find the point at which
So, we have:
To solve the quadratic function we use the quadratic formula
±
Where:
Then:
The line cuts the parabola by 2 points, x = -1.472 and x = 7.47.
You can verify that between x = -1.472 and x = 7.47. the line is greater than the parabola, but from x = 7.47, the parabola is always greater than the graph of the line.
Therefore the point sought is:
x = 7.47≈ 8
Answer:
1.6% shrinkage
Step-by-step explanation:
907,340 - 875,435 = 31,905
31,905 / 1,988,345 = .0160 = 1.6%
The answer for this question is 0.22
The answer is C. You can solve these by plugging in and checking if each equation is true with the given answers. Also, you can solve by using elimination to get one of the variables removed. Then when you have two, two-variable problems, you can solve that system in any of the ways.
