12^-6/12^7

When dividing the only thing you do is subtract the exponents from each other.

-6-7

In this case, you have to subtract a number from a negative. -6-7 would actually be -6+-7.

-6+-7= -13

12^-13 is the final answer

Q1. Look at the picture.

$C.\\y=-\dfrac{1}{3}x+3\\\\y=2x-4$

Q2. Look at the picture.

$A.\ 4-t$

Q3.

Put the value of x = 2 to the equation 3x + y = 5:

$3(2)+y=5$

$6+y=5$ <em>subtract 6 from both sides</em>

$y=-1\\\\F.\ -1$

Q4.

$\left\{\begin{array}{ccc}n=3m-11&(*)\\2m+3n=0&(**)\end{array}\right$

Substitute (*) to (**):

$2m+3(3m-11)=0$ <em>use distributive property</em>

$2m+(3)(3m)+(3)(-11)=0$

$2m+9m-33=0$ <em>add 33 to both sides</em>

$11m=33$ <em>divide both sides by 11</em>

$m=3$

Put the value of m to (*):

$n=3(3)-11\\\\n=9-11\\\\n=-2$

$C. (3,\ -2)$

Q5.

w - width

3w - length

24 in - the sum of length and width

The equation:

$w+3w=24$

$4w=24$ <em>divide both sides by 4</em>

$w=6\ in$

$3w=3(6)=18\ in$

$J.\ 18\ inches$
