It depends upon the relative sizes of the numbers:

It could be negative:  -6 - (-2)   =  -6 + 2    =  -4

If could be zero:        -6 - (-6)   =  -6 + 6    =  0

It could be positive:  -6 - (-10)  =  -6 + 10  =  4

If you subtract a positive number from a negative number, the answer will always be negative.

You can use the slope formula:     m  =  (y2 - y1) / (x2 - x1)

(x1, y1)  =  (2, 3)                   (x2, y2)  =  (7, -4)

----->     m  =  (-4 - 3) / (7 - 2)  =  -7/5 

x² - 16x + y + 68  =  0

--->  y  =  -x² + 16x - 68

Complete the square:

--->  y + 68  =  -x² + 16 x

Factor out the negative sign:

--->  y + 68  =  -(x² - 16 x)

Complete the square by dividing the linear term by 2, squaring the rsult and adding that result to both sides:

--->  y + 68 - 64  =  -(x² - 16x + 64)

--->  y + 4  =  -(x - 8)²

The vertex is:  (8, -4)

The focal length is found using:  f  =  1/(4a)   --->   f  =  1/(4·-1)  =  -1/4

The focal point will be at (8, -4 - 1/4)  =  (8, -4 1/4)

The directrix will be:  y  =  -4 + 1/4   --->   y  =  -3 1/4

Let's see ... since there are 180° in a triangle, the third angle of the first triangle has 180° - 95° - 60°  =  25°.

Since there are  35°  in an angle of the second triangle, there is no chance that the second triangle can be congruent to the first triangle ...

It doesn't make any difference if you are using SAS, SSS, or any of the other congruences.

fI have no idea what  a² + b³  =  c⁴  has to do with the rest of the problem.

     2.347 + (x/8.253)  =  24

Subtract  2.347  from both sides:  (x/8.253)  =  21.653

Multiply both sides by 8.253:                       x  =  178.7  (approx)

If the length of one side of a cube is  x  then the area of that side is  x².

Since a cube has 6 sides, the total surface area is  6x².

If the total surface area is  48     --->     6x²  =  48

       Divide by 6:                                      x²  =  8

       Find the square root:                          x  =  √8

33.3% of 10%  =  0.333 x 0.10  =  0.0333  =  3.33%

You can use the slope formula:     m  =  (y₂ - y₁) / (x₂ - x₁)

(x₁, y₁)  =  (3, 6)                   (x₂, y₂)  =  (-1, 2)

----->     m  =  (2 - 6) / (-1 - 3)  =  -4/-4  =  1

A formula for the circumference of a circle is:     C  = 2·π·r

     --->     C  =  2·π·3.2  =   ..........    <---   the answer 

With each shirt you can wear any one of 5 different pairs of pants.

5 different pants for each of 3 shirts:  3 x 5  =  15 outfits.

Add the lengths of the four sides; there is no general formula.

Simpler than what?

Can you give more information?

(l - r)³  =  (l - r)(l - r)(l - r)  =  (l - r)[(l - r)(l - r)]  

     =  (l - r)[1 - 2r + r²]                 FOILing (1 - r)(1 - r)

     =  1 - 2r + r² - r + 2r² - r³]      (multiplying out)

     =  1 - 3r  + 3r² - r³                   (simplifying)

Usng the Distributive Property:  (2/3)(2x) - (2/3)(9)  =  (4x)/3 - 6

Rearranging the factors:  (r·r)(s·s³·s²)  =  r²·s⁶          (adding exponents)

It's a negative number.

Try using a number line. You're at a negative number, and you're moving backward. Your number is still negative.

Hope this helps.

1/8 divided by 3/8 is the same as 1/8 time 8/3.

To find 1/8 times 8/3, you multiply 1*8 and put it over 8*3.

1*8= 8. 8*3=24. So you get the answer 8/24, which can be simplified to 1/3.

Thank you! This website is really helpful!

The subtraction property of equality....

$$\frac{8}{1/3}$$

To divide a number by a fraction in which the numerator (top) is one, is the same as to multiply the number by the denominator:

$$\frac{a}{1/b} = ab$$

So in our case:

$$\frac{8}{1/3} = 8*3 = 24$$
