Answer:

4a^{5}

Step-by-step explanation:

\frac{64}{16} = 4

When the bases are the same and you are dividing you subtract the exponents.  It is easier to see why when you write the problem out in expanded form.

\frac{aaaaaabbbbbbb}{abbbbbbb}  If you cross out all of the a's on top with the a's on the bottom, you are left with only 1 a (6-1 = 5)  If you do not see an exponent, it is understood to be 1.  All of the b's on the top and bottom cross out. (7-7 = 0)  Anything to the zero power = 1.

Answer:

4a^{5}

Step-by-step explanation:

The easiest way to start this solving is simplifying the numbers:

start by dividing 64 by 16. This gets you 4.

Then simplify the variables. Let's start with <em>a</em>:

to do this, we will start by moving all the <em>a'</em>s to the same line so we can multiply them

multiplying like variables means that you are actually just adding their exponents

when moving a variable up or down on the fraction, the exponent will flip signs (positive to negative, or negative to positive)

in this case, we have a^{6} in the numerator and a^{1}, so it would be easiest to move   a^{1} above so that it the equation will become \frac{4a^{6}a^{-1}b^{7}   }{b^{7} }

now we can subtract 1 from 6 and get  \frac{4a^{5}b^{7}   }{b^{7} }

Now let's work on simplifying <em>b:</em>

both the numerator and denominator have b^{7} in it

so if we move the <em>b</em> denominator up, the numerator ends up as     {4a^{5}b^{7}b^{-7} }

which makes both <em>b'</em>s cancel out, making your final answer 4a^{5}

anyanavicka [17]

Answer:

y = 3x + 15

Step-by-step explanation:

1. Find the reciprocal of the slope and change signs: -3

2. y = 3x + b

3. Plug in x and y --> b = 15

4. Make your equation using y = mx + b: y = 3x + 15

(x² + 4x - 45)/(x² + 10x + 9) 
<span>
Numerator = N = x² + 4x - 45 </span>
= x² + 9x - 5x - 45 
= (x² + 9x) - (5x + 45) 
= x(x + 9) - 5(x + 9) 
= (x + 9)(x - 5)

Denominator = D = x² + 10x + 9 </span>
= x² + x + 9x + 9 
= (x² + x) + (9x + 9)
