Algebra help please
ask away.
Hang on! :D
I am hanging
Also are you good with geomrty?
Ask anything, and see if I can do it, test me will see how much I am worth.
B&C?
find to points on the line, and plug them into a slope formula. Do you know what the slope formula is?
yea
my bad, (4,3) and (8,6)
\[\frac{3-6}{4-8}=slope\]
\[\frac{3}{4}=slope\]
were my answers rite?
So according to your graph y coordinate is $, and Euro is the x coordinat so B and C, are true. See why?
Yes
B A C
are you asking to check your work? and your answers are B A C?
Do u give answers??
Not on this website, the user are not allowed to give plain answers for math problems, unless they are 1+1 type of thing.
Oh okay, well can you check my work and see if i got them right? and ym answers are B A C
Yup! All are correct!
D
I would right this as 10+2/5m m= number of minutes. I don't think your choices are correct.
A?
looking at the graph you can see that 50 minutes cost 20$, and 100 minutes cost 30$ so I think I was incorrect, but from the above statement, what conclusion can you make?
I was confused, b/c each x unit is 10, and y unit is 5.
would it be .20?
10+1/5m
yes!
b/c for each 25 minutes it is 5 bucks, so 5/25=.2
A?
for the first one it B, you can see that if you look at .30=1 → 30=100
D?
why d? your graph represents a line if you try to write the equation of your problem in y=mx+b form you will see why it is A.
Wait so i had it right first time. it was A?
In this case, there is no extra fee, just a cost of call per minute, therefore in your equation the variation of x to y is direct, in other words no y intercept, or y intercept=0 so $30=100 you can put this as 100y=30x, correct? so divide both sides by 100, .... y=.30x or more correctly, mathematically, y=.3x so the variation k, or the slope is .3
so A?
yes! Do you see why though?
B? yes!
I think C, why? Because in your equation the y intercept is 2000, slope is 500 so, y=500x+2000 Now, what does the x on the graph represent the number of months so it is 500. Another way to explain this, is just to simply look at the graph, it is increasing every unit by, 1 month and 500 miles. See?
C? and yes!
Yup!
