Multiply both sides by -3 to get rid of the negative and the fraction.
X - 3 = 21
Move the constants over to isolate the variable
X = 24
Please present the relationship in a table arranged vertically:
<span>this relationship. X= 0, 2, 4, 6, Y= 0, 8.4, 16.8, 25.2 becomes:
</span><span> x y
--- -----
0 0
2 8.4
4 16.8
6 25.2
Notice that as x increases by 2 units from 2 to 4, y increases by 8.4 units to 16.8. Thus, the slope of this line is
16.8
m = -------- = 8.4
4-2
Your problem statement sounds incomplete; what were you asked to do here?
You could compare the equations of the 2 functions:
y = 4.2x and
y = 8.4x
The slope of the 2nd function is twice that of the first function. Both graphs go through the origin, (0,0).</span>
Answer:
An adults ticket costs $9
Step-by-step explanation:
Kids:
$7
Adults:
$9
So if you add 7+7+7= 21 (kids)
then do 9+9=18(adults)
Then add them together you get 39$
Looking at the graph, we'll notice that there is a local maximum at x=0 and it looks similar on both sides of the y axis, therefore making it symmetric around the y axis given the options
