Step-by-step explanation:
You can't use quadratic formula in this
ivied the total number of tennis balls buy the number of cans to see how many tennis balls are in 1 can
9 divided by 3 = 3
there are 3 tennis balls per can
fraction would be 3/1 ( meaning 3 balls to 1 can)
(-1,3) (2,-3) (-5, -1) (-6,-4)
Step-by-step explanation:
3x/2 - 2 > 7
3x/2 > 9
3x > 18
x > 6
for the line graphic below it seems you need to calculate x.
please consider that both angles together must be 180°, as they represent the full rotation area around one point on one side of a line.
8x + (4x + 60) = 180
8x + 4x + 60 = 180
12x = 120
x = 10
Answer:
<em>Correct answer: C. (1,∞)</em>
Step-by-step explanation:
<u>First Derivative</u>
Given a real continuous function f(x), the first derivative f'(x) represents the slope of the tangent line for any value of x.
If the slope of the line is positive, then the function is increasing, if the slope of the line is negative, the function is decreasing.
The function to analyze is:
![f(x)=x^2-2x+1](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2-2x%2B1)
Computing the first derivative:
![f'(x)=2x-2](https://tex.z-dn.net/?f=f%27%28x%29%3D2x-2)
The function will be increasing when:
![2x-2>0](https://tex.z-dn.net/?f=2x-2%3E0)
Dividing by 2:
![x-1>0](https://tex.z-dn.net/?f=x-1%3E0)
Solving:
x > 1
This solution is represented by the interval (1,∞)
Correct answer: C. (1,∞)
