14. Range=22 Mean= 31.2
15. Range=33 Mean= 88.2
16. Range= 81 Mean= 161.3
To find range you take the smallest number and the largest number and subtract them. To find mean you add all of the totals together and then divide by how many numbers are given.
Answer:
Step-by-step explanation:
X^4+x=0
X(X^3+1)=0
X(X+1)(x^2-x+1)=0
X=0, x=-1, x=(1+3^1/2i)x=(1-3^1/2i）
Slope intercept form is y=mx+b
you can later plug in values to make your own slope intercept form.
1) x=
square root ({15}^{2} - {9}^{2} )
all the others are the same method, just remember
the horizontal line^2 + the vertical line ^2 is equals to the line opposite the right angle^2
Answer:
3/4
Step-by-step explanation:
The slope of the line can be found by
m = (y2-y1)/(x2-x1)
= (-6- - 9)/(6-2)
= (-6+9)/(6-2)
3/4
