Answer:
3
-27x-30
=3
-(30-3)x-30
=3
-30x+3x-30
=3x(x-10)+3(x-10)
=(3x+3)(x-10)

Answer:
see below
Step-by-step explanation:
Starting from the point-slope equation ...
y -y1 = m(x -x1)
Solving for y gives ...
y = mx +(y1 -m·x1)
So, the slope-intercept form equation is fairly easily found:
y = mx +b . . . . where m = m, and b = y1-m·x1
This is the equation we have used for 'b' in the attached spreadsheet.
__
Of course, the formula for slope is ...
m = (y2 -y1)/(x2 -x1)
This is the equation we have used for 'm' in the attached spreadsheet. For all problems, we have used the first point. (It doesn't matter which point you use if there are two of them.)
__
The second attachment is the Google Sheets spreadsheet saved in ODS format. Most spreadsheet programs should be able to open that so you can see the formulas, if you're interested. (The gray values of m are computed using the two points. The unshaded values of m are entered by hand.)
_____
I'll write a couple of equations in each group so you can see how the spreadsheet numbers relate:
y = mx +b
1. y = 2x -7
3. y = 2/3x +4
8. y = 1/3x -5
9. y = -5/2x +4
Answer:
Hello!
To answer your question:
8% of 23,400 is 1872.
23,400- 1872= $21,528 by the end of the first year
1 year=12 months
1872/12= $156- this is how much it is decreased monthly.
156 is 0.67% of 23400, so the monthly percent decrease of 0.67%.
Hope this helps, and hope this is right! :)
