So the slope is (y2-y1)/(x2-x1)
(8-4)/(2-1)=
4/1 =
4
Aka. For every 1 week, the number of pictures taken increases by 4.
So it is 4 * w
Check:
4*w = total number of pictures
4*1 = 4
4*2 = 8
4*3 = 12
4*4 = 16
All match the table.
Part A: Factor 3x2y2 − xy2 − 2y2. Show your work. (4 points)
3x^2y^2 − xy^2 − 2y^2
y^2 ( 3x^2 - x -2 )
y^2 (3x+2)( x - 1)
Part B: Factor x^2 + 6x + 9. Show your work. (3 points)
x^2 + 6x + 9
= x^2 + 2*3x + 3^2
= (x+3)(x+3)
= (x+3)^2
Part C: Factor x2 − 25. Show your work. (3 points)
x^2 - 5^2
<span>(x-5)(x+5)</span>
The lines on the triangles
5(0)-4(0)^2+3
Answer:
=3
