Answer: -1+6y+7x

To simplify expressions, you have to be able to combine like terms (eg. 3x and 2x to get 5x). Since there are none in this expression, and you can't combine y and x, this expression can't be simplified.

*If it helps, think of x and y as different types of candy... ;3

For example, you can't combine 12 Skittles (x) and 4 Reese's (y), because they aren't the same. So, you'd write that you have 12 Skittles and 4 Reese's.

Hope this helps,

Alchen [17]

Answer:

Constant of proportionality is 12

The cost of buying new bicycle changes 12 dollar per week

Step-by-step explanation:

we are given

The equation as

$d=12w$

where

d represents the amount in dollars

w is number of weeks

now, we can compare it with

$y=kx$

where

k is constant of proportionality

we can compare

and we get

k=12

So,

Constant of proportionality is 12

we can see that

$12=\frac{d}{w}$

So,

The cost of buying new bicycle changes 12 dollar per week

Nimfa-mama [501]

<h3>Answer: 180 degrees</h3>

note: it doesn't matter if its clockwise or counterclockwise when it comes to 180 degree rotations.

========================================

Explanation:

The rule for 180 degree rotations is

(x,y) ---> (-x, -y)

So the x and y coordinates flip in sign from positive to negative, or vice versa.

Point D ' (-3, 5) rotates to D ' (3, -5) following this rule

-----------------

A further detailed break down might look like this

x = -3 becomes -x = -(-3) = 3

y = 5 becomes -y = -5

(-3, 5) ----> (3, -5)
