Answer:  25

<u>Step-by-step explanation:</u>

   7(x - y) - 3(2 + 2x)

= 7x - 7y  - 6  - 6x

=   x - 7y  - 6

for x = 3, y = -4

      3 - 7(-4) - 6

=     3 + 28  - 6

=         31     - 6

=             25

Mazyrski [523]

Answer:

Step-by-step explanation:

Length=2*Width

L=2*W

Perimeter=28.8 cm

Perimeter of a rectangle= 2(Length+Width)

28.8=2(2W+W)\\\\28.8=2(3W)\\\\3W=28.8/2\\\\3W=14.4\\\\W=14.4/3\\\\W=4.8 cm\\\\

Length=2*Width\\\\=2*4.8\\\\=9.6 cm\\\\

Length=9.6 cm\\\\Width=4.8 cm

The manager of a 100-unit apartment complex knows from experience that all units will be occupied if the rent is $800 per month.
Ede4ka [16]
800 * 100 = 80000
810 * 99 = 80190
900 * 90 = 81000
1000 * 80 = 80000
(800 + 10n) (100-1n)
=(800 +10(11)) (100 - 11)<span> (910)(89) = 80990</span>

2. y=2x+3 

When x =0 and y= something, the 'something' is your y-intercept which is b in the y=mx+b formula.  Then we look at what is changed in the x and y value to determine the m part.  the x increase by 1 and y increase by 2 so the m part is 2. 

3. y=-7x 
Same as the last one, there is no y-inter this time because the y=0 when x=0/  So the y deceased by 7 each time and x incease by 1 so it is -7 for the m part.
