What does the algebraic representation (x, y) → (-x, y) represent?

Hi there!

I believe your answer is:  

A translation 9 units to the right and 3 units down.

Here’s why:  

Therefore,

The algebraic representation of what's given is a transformation of a point that is translated 9 units right and 3 units down.

Hope this helps you. I apologize if it’s incorrect.  

Explanation:

Consider the point (1,2). If we apply the rule , then it would move to (-1,2).

The x coordinate flipped in sign from positive to negative. The y coordinate stays the same.

Another example is (-3,7) reflecting to (3,7).

the awnser is a

Step-by-step explanation:

the awnser is a

Step-by-step explanation:

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

The answer is in the image 

The answer is in the image 

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg
