Answer:

Step-by-step explanation:
The slope-intercept form of an equation of a line:

<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:

We have two points (2, -2) and (4, -1).
Substitute:

Put the value of a slope and the coordinates of the point (2, -2) to the equation of a line:

<em>subtract 1 from both sides</em>

Finally:

Answer:
it's a 0.02% error.
147/150= 0.98% of the folders are there, making the error 0.02%
Step-by-step explanation:
Split it up
3x^2+12x-5x-20
group
(3x^2+12x)+(-5x-20)
factor
(3x)(x+4)+(-5)(x+4)
undistribute (x+4) like ab+ac=a(b+c)
(3x-5)(x+4)
D. F(x)=x^2. That’s The quadratic parent function
