Step-by-step explanation:
Let's pick two points on the line:
and
Let's calculate the slope of this line using these points:

With this value of the slope, we can write the general slope-intercept form of the equation as

To solve for the y-intercept b, let's use either P1 or P2. I'm going to use P2:

Therefore, the slope-intercept form of the equation is

-x^2+2x+3=x^2-2x+3 add x^2 to both sides
2x+3=2x^2-2x+3 subtract 2x from both sides
3=2x^2-4x+3 subtract 3 from both sides
2x^2-4x=0 factor
2x(x-2)=0
So x=0 and 2
Answer:
-8-(-1)-5
Step-by-step explanation:
(Hope this helps can I pls have brainlist (crown) ☺️)
4/10 multiplied to 2/3 is 4/15.
There are 21 people, everyone hugs each other, but the person hugging cant hug themself, so (21*21)-21
(21*21) -21 = 441
441-21=420
