Answer:
a reflection over the y-axis
Step-by-step explanation:
When a point is reflected over the y-axis, the images forms where the y-coordinate remains the same while the x-coordinate is transformed to the opposite sign.
In this case, a point (x,y) transforms to (-x,y). From the coordinates given;
(-3,3) --------(3,3)
(-1,3)----------(1,3)
(-2,1)----------(2,1)
See attached plot of object points and image points.
Answer: OPTION C.
Step-by-step explanation:
Given a System of equations, you can use the Elimination Method to solve it by transforming the system in order to cancel out one of the variables. But first, the terms of both equations must be written in the same order.
To cancel out one of the variables, the coefficients must be opposites, which means that one must be positive and the other one must be negative.
Given the following System of equations:
You can notice that the order of the terms is not the same, so, if you want to use the Elimination Method to solve the system of equations, the first step you must apply is to rewrite the equations so like variable terms are in the same order.

Answer:
1. Benny had 266 dollars to spend on 9 books. After buying them, he had 14 dollars. How much did each book cost?
The books cost $28 dollars each.
<em>how to calculate...</em>
<em>
$266 - $14 = $252
</em>
<em>
then take $252 divided by 9 = $ 28</em>

2. Oceanside Bike Rental Shop charges 14 dolars plus 9 dollars an hour for renting a bike. Sally paid 86 dollars to rent a bike. How many hours did she pay to have the bike checked out?
8 hours
how to calculate...
take 86 - 14 = 72
then 72 divided 9 = 8 hours
3. The sum of three consecutive numbers is 132. What is the smallest of the three numbers?
43 is the smallest of the 3 numbers
<em>calculation...</em>
<em>x + (x+1) + (x+2) = 132</em>
<em>3x + 3 = 132 -3</em>
<em>3x=129
</em>
<em>x=129/3
</em>
<em>
x=43 (answer for the 1st number)</em>
<em>43+1=44 (answer for the 2nd number)</em>
<em>43+2=45 (answer for the 3rd number)</em>
add them all to make sure they equal to 132
<em>43+44+45=132
</em>
<em>132=132</em>
4. Sandy sold half of her comic books and then bought 8 more. She now has 16. How many did she begin with?
x= how many Sandy started with
<em>1/2 x + 8 = 16</em>
<em>1/2x = 16 - 8</em>
<em>1/2x = 8 * 2</em>
x = 16 comics books

Step-by-step explanation:.
Answer:
y = 150
Step-by-step explanation:
y varies inversely as x²
yx² = k
----------------
y = 6 when x = 30
6(30²) = k
6(900) = 5400
--------------------------
what is y when x = 6
y(6²) = 5400
y(36) = 5400
y = 5400/36
y = 150
