Answer:
(21, 7)
because the x axis is the number of minutes and the y axis is the x axis divided by 3
Answer:
dude
Step-by-step explanation:
which one is 3 and 4?
Answer:
One solution (-1,2)
Step-by-step explanation:
Since these two linear equations have different slopes, different y-intercepts, and are indeed linear, these equations will only have one crossing when graphed, and hence one solution.
To find that solution, we can simply set the equations equal to each other.
y = -x + 1
y = 2x + 4
-x + 1 = 2x + 4
-3 = 3x
-1 = x
Now plug that value back into one of the equations:
y = -x + 1
y = -(-1) + 1
y = 2
So now you know the crossing for these two equations occurs at (-1,2).

Answer: at new cost increase is 30%
after additional $4.50 fee increase would be 45%
Step-by-step explanation:
use equation
30:100=39:x
30x=3900
x=3900/30
x=130
130-100=30%
39+4.50=43.5
30:100=43.5:x
30x=4350
x=4350/30
x=145
145-100=45%
It's a difference in displaying it. Line chart will draws values on one axis with line, bar chart draw vertical bars from 0 value to proper value.
