Your in 8th grade I see me too
also yes it’s a function.
It is easier to do one question at a time
collinear points lies in a single line
that means sum of distance between 2 points is equal to distance between end points.
for example if A B and C lies in a line then
AB + BC = AC
here (1,1) , (2,2) and (3, 3) follows the same rule. ao ans is option D
Ughhh I’m not totally sure but I’ll see what I can do to help you
<span>Solve the following equation in the real number system. Please show all of your work.
example:
x³-6x²-10x+12=0
...
f(x)=x³-6x²-10x+12
A graphing calculator will show that there is one zero at x=-2
Divide f(x) by (x+2) by long division or synthetic division
(x³-6x²-10x+12)/(x+2)=x^2-8x+6
solve for other two zeros
x^2-8x+6=0
complete the square
(x^2-8x+16)+6-16=0
(x-4)^2=10
x-4=±√10
x=4±√10=7.16 and -.84
ans:
x=-2, -.84 and 7.16</span>
