It would be 2x-20. Explanation: for inverse’s, you flip the y and the x and then solve for y to get your inverse. So, the equation would look something like
X = 1/2 y +10
I would then subtract 10 from both sides
X - 10 = 1/2 y
And then to get y by itself, you must multiply both sides by 2
2x - 10 • 2 = y
Getting the equation
2x- 20 = y
Answer:
6 pk noisemakers (6 x 5 = 30 noisemakers)
1 pk balloons (1 x 30 = 30 balloons)
Step-by-step explanation:
divide 30 by 5, = 6
buy 6 packs noisemakers and one pack of balloons
Remark
You should always write proportions the way you normally do first. Most people write a proportion as
4/20 = 2 / 10 Using colons helps to make clear what is comparred all on one line.
4:20::2:10
:: is the equal sign
/ is the division sign.
: (a single colon) takes the place of /
9/27 = 2 / 6
Which can be
9:27::2:6
Note
The colon method is not in current use as much as it was.
Answer: Hexagon AGHBGHCGHDGHEGHFGH coincides with hexagon ABCDEF when GH passes through themidpoints of opposite sides; that is, it is a perpendicular bisector of the two sides. HexagonAGHBGHCGHDGHEGHFGH also coincides with hexagon ABCDEF when the line of reflection joins a pair ofvertices opposite one another on the hexagon. There are three perpendicular bisectors and three pairs ofopposite vertices. In all, there are six lines of reflection that will map the hexagon back onto itself.
