The tool I used for modellin is MS Excel. As you on the left side of the picture, I tabulate the x and y coordinates with respect to their columns. Then, I plotted it using the scatter plot graph. In this type of graph, only plots are drawn on the Cartesian plane. Next, I created a trendline as represented by the blue dashed line. There are options to the degree of your trendline: linear, polynomial or exponential. The closes fit is the polynomial with a degree of 2. An option is listed there in displaying the equation. The equation modelled by regression through data fitting is:
y = x² - 4x+1

Answer:
Step-by-step explanation:
5ab×2c×11 + 2bc×5
multiply the numbers
110abc+2ab×5
110abc+10ab
factor out 10ab from the expression
10ab×(11c+1)
Answer:
x is 3 or 4
Step-by-step explanation:
- I assume that you want to find the solutions for this quadratic equation
- First of all, set it all to equal 0
- Now you need to factorise your expression
- You need to find two numbers that multiply together to make 12, and ad together to make -7
- These two numbers are -3 and -4
- Your new equation is:
- For this equation to equal 0, just one of x - 6 and x - 1 has to equal 0
- For x - 3 to equal 0, x has to be 3
- For x - 4 to equal 0, x has to be 4
- x = 3 or 4
