1 solution, that solution is 3.
Answer:
14
Step-by-step explanation:
just look at the chart and add the amount of students that got 80-89 and then the amount that got 90-100
8+6=14
The answer is 1
Use the discramnt formula
![{b {}^{2} - 4ac }](https://tex.z-dn.net/?f=%20%20%7Bb%20%7B%7D%5E%7B2%7D%20-%204ac%20%7D%20)
Where a is 81, B is 18, and c is 1
We get
![18 {}^{2} - 4(81)(1)](https://tex.z-dn.net/?f=18%20%7B%7D%5E%7B2%7D%20%20%20-%204%2881%29%281%29)
We then get 324-324=0
Which equal 0. Since the discramnt produce 0, the number of solution is one and repeated.
Answer:
Because as u get older u gain more knowledge and they give more work caue u have more knowledge
Step-by-step explanation:
Find the slope of the line using the equation (y1-y2)/(x1-x2), which is change in rise over change in run. use any two points, for example (2,-2) and (3,-1). using the formula, (-2-(-1))/(2-3) is the rate of change, giving you -1/-1 as the slope, which is -1. the rate of change is -1.
