y - 0 = 5/-3(x - (-4))

Drop the -0; change 5/-3 to -5/3; change - (-4) to +4:

y  =  -5/3(x + 4)

Use the distributive property:   multiply through by -5/3:

y = (-5/3)x - 20/3

Slope = -5/3

Y-intercept = -20/3

what about 21           :-D

Does 0145 repeat or does just 145 repeat?

If the number is 2.014501450145...

Let n = 2.01450145...

Then multiply by 10000, to move a 4-digit array:

                10000n = 20145.01450145...

                         n =         2.01450145...

Subtract:    9999n  =  20143.00000...

                         n  =  20143 / 9999

If the number is 2.0145145145...

Let n = 2.0145145145...

Then multiply by 1000, to move a 3-digit array:

                 1000n = 2014.5145145...

                         n =      2.01450145...

Subtract:      999n  =  2012.500000...

                         n  =  2012.5/999  =  20125/9990  =  4025/1998

If you start with twelve pieces of toast and you eat two, you still have ten pieces left (12 - 2 = 10).

331 + -8  =  331 - 8  =  323

Adding a negative is the same as subtracting.

Set up a proportion:

80 ounces / 1250 sq ft  =  x ounces / 4000 sq ft

Cross-multiply:

1250 · x  =  80 · 4000

1250x  =  320,000

x  =  320,000 / 1250  = 256 ounces

To find the number of 32 ounce cans:

256 / 32  =  8 cans

8 cans at $1.19 per can  =  $9.52

78 = -6(8k - 9) - 12(k + 6)

Use the distributive property:

78 = -48k + 54 - 12k - 72

Simplify:

78 = -60k - 18

Add 18 to both sides:

96 = -60k

Divide by -60 and reduce:

k = 96/-60 = -8/5 

a)

80/1250 = x/4000   cross-multiply

4000(80) = 1250x     simplify

320000 = 1250x       divide both sides by 1250

320000/1250 = x = 256  

b) 

$1.19/32 =x/256           again, cross-multiply

304.64 = 32x                divide by 32 on both sides

$9.52 = x

The formula for the slope of a line is  m  =   (y2 - y1) / (x2 - x1).

Letting x1 = -7, y1 = 9, x2 = -7, and y2 = 3:  m  =  (3 - 9) / (-7 - -7)   =  -6 / 0  <-- undefined.

It's a vertical line, so it has "no slope" or an "undefined slope".

If he has total expenses of $600.00 (for all the apartments combined) and if he wants to make a total profit of $500.00, he would need to charge a total of $1100.00. 

Dividing $1100.00 by 4, he would have to charge $275.00 each.

you would just add 500 and 600 for the amount charged to each apartment

2300000000

Use a proportion, in this case $${\frac{{\mathtt{x}}}{{\mathtt{6.87}}}} = {\frac{{\mathtt{20}}}{{\mathtt{100}}}} \Rightarrow {\mathtt{x}} = {\frac{{\mathtt{687}}}{{\mathtt{500}}}} \Rightarrow {\mathtt{x}} = {\mathtt{1.374}}$$

Note...3 + 1/4 = 3.25      so we have

5800/1hr = x /3.25hrs     cross multiply

3.25 * 5800  = 1x

18850  = x         and that's how many they can print in 3.25 hrs

Since he pays out $600 each month and he wants to make a proit of $500, he must collect $500 more than his expenses....so.....600 + 500 = 1100  ....so he must collect $1100 in rent from the 4 apartmenrs.

And the amount he must collect from each is just  $1100/4 = $275

At least try and make it seem that you didnt directly copy this from your math homework XD

7/7 = 1  ...... so.......

7 + 1 + 1 = 9

The meaning of life is to complete any dreams or goals that you have. Whether small or big, there will always be something that you have to accomplish or achieve in your life, and will be until the day you pass. Not a math question at all, but glad to help 

5(x-3)+12 = -2(x+7)      distribute the 5 and -2 over the terms in the parentheses

5x - 15 +12 = -2x - 14    simplify

5x - 3 = -2x -14              add 3 to both sides and add 2x to both sides

7x = -11                          divide both sides by 7

x = -11/7

Obvious troll, but its 19

4           

Note that y appears to change by 1 when x changes by 4.......so the slope of our function is 1/4

And using one of the points (12, 2.5)   we have  ...in point-slope form ....

y - 2.5 = (1/4)(x - 12)      add 2.5 to both sides

y = (1/4)(x - 12) + 2.5     distribute the 1/4 across the terms in the parentheses

y = (1/4)x - 3 + 2.5         simplify

y = (1/4)x - 1/2             so when x = 8, y should = 1.5...let's see if that's true

y = (1/4)(8) - 1/2

y = 2 - 1/2 

y = 3/2 = 1.5

So....our equation is correct

i think you just plug in the numbers if its multiple choice question if not go with his↑↑↑↑↑↑↑↑
