Answer:
y = -0.9x+10.1
Step-by-step explanation:
The equation of the line is:
You have been asked to stimate m and b. To do so, first find the product between each pair of x and y and the value of x squared:
Then calculate the total sum of all columns:
m can be calculated following the next equation:
where n is the number of (x, y) couples (5 in our case).
Replacing the values calculated previously:
For b:
In the figure attached you can see the points given and the stimated line.
Answer:
4+m
Step-by-step explanation:
You can't put them together 'cause they aren't like terms, so you just keep the sign that put them together in the first place.
Answer:
-7/10
Explanation:
Substitute x with 3 first and you’d get 3/10(3(4)+9)-7. 3(4) is 12 plus 9 is 21. 3/10 multiplies by 21 is 6 3/10. 6 3/10 minus 7 is -7/10
Answer:
Option (2)
Step-by-step explanation:
Standard form of the polynomial will be in the form of (ax⁴+ bx³+ cx²+ dx + e).
Which means exponents of each successive term will be in the reducing form and the last term will be a constant term.
Now we can rearrange the terms of the given polynomial (5x + 2x⁴ - 4) for the standard form.
(2x⁴ + 5x - 4)
Since, degree of the leading term = 4
And number of terms = 3
Given polynomial is a fourth degree trinomial.
Option (2) will be the answer.
