Find the value of y when x equals 17 -x+y=-27
since x is equal to 17 you plug it in the equation as follows...
-17+y=-27
then you add 17 on both sides...
y=-27+17
Answer:
y=-10
To add the variables, add the coefficients with same variable. The expression which is equivalent to given expression is 
. The option 2 is the correct option.
<h3>What is
equivalent expression?</h3>
Equivalent expression are the expression whose result is equal to the original expression, but the way of representation is different.
Given information-
The expression given in the problem is,
Let the resultant expression of the above expression is 
. thus,
To add the algebraic terms open the brackets first,
Separate the same variable terms,
To add the variables, add the coefficients with same variable. Thus,
Hence, the expression which is equivalent to given expression is . The option 2 is the correct option.

Step-by-step explanation:
90 Degree Rotation. When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A'(-y,x). ...
180 Degree Rotation. When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). ...
270 Degree Rotation.
Answer:
to find how many sales Ross made in a day divide 27 by 3 and to find Mona's divide 49 by 7 since there is 7 days in a week
Step-by-step explanation:
27/3 = 9 so Ross made 9 sales in a day
49/7 = 7 so Mona made 7 sales in a day
9>7
therefore Ross made more sales
