<span>You can get those ordered pairs subtracting 9-0.5, then that result minus 0.5 because from the rate the candle reduces its height 0.5inches per each hour.Part B: Is this relation a function? Yes, because each value of x has a single result or output in “y” (image)Part C: Yes, only difference is the time, the candle reduces its height 0.45 inches per each hour, examples of ordered pairs: (0,9) (1,8.55) (2,8.1)</span>
D (5, -5)
E (2, -7)
F (6, -1)
G (10, -8)
If you need an explanation as to how I did, you just add 4 to the x coordinate and subtract 5 from the y coordinate since going down is negative.
Answer:
x=-1
Step-by-step explanation:
-2x-3=x
add 2x to both sides
-3=3x
divide both sides by 3
-1=x
<h2>Answer: X = 2/11</h2><h3>To solve for x by simplifying both sides of the equation, then isolating the variable.</h3><h3>Exact Form:</h3><h3>x = 2/11</h3>
Cody: 2x
Evan: x
x-7 (Evan’s age 7 years ago (-7))
2x-7( Cody’s age 7 years ago (-7))
So you add both
x-7+2x-7
And that should equal 7 (seven years ago the sum of their age was 7)
x-7+2x-7=7
3x-14=7
3x=21
x=7
Evan (x)= 7
Cody (2x)= 7 times 2
Cody= 14
