Standard form is ax²+bx+c
expand then simlify
-(x-4)²=-(x-4)(x-4)=-(x²-8x+16)=-x²+8x-16
now we gots
-x²+8x-16-1
-x²+8x-17 is standard form

Step-by-step explanation:
The equation is in point-slope form, so you can read from the equation that one of the points on the graph is (2, 5).
The slope of 3/2 tells you that going 2 units to the right (to x=4) will move the point up 3 units (to y=8).
You can draw your line through these two points: (2, 5) and (4, 8).
You need to do $200 -$92 =108. 108 divide by 4 is 27. so you would need to make 27 sales
There is a 4/6 chance to roll a 2 or an odd number. These events are not mutually exclusive.
