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

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 

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.

Sin can never have a value smaller than -1 nor can it have a value larger than +1.

invSin(1.09) is impossible.

It's not solvable in the sense that there is only one set of values for x and for y that makes the statement true.

For instance, when x = 5, y = 3 and when x = 10, y = 5.5.
