Question

i need help

Answer 1

do u know this @texaschic101

Answer 2

i know its a or b but i think more a

Answer 3

@StudyGurl14

Answer 4

y = 1/3x - 2
In y = mx + b form, the m is your slope and the b is your y intercept.
So we have a slope of 1/3 and a y intercept of -2....or (0,-2)
to find the x intercept, we sub in 0 for y...
0 = 1/3x - 2
-1/3x = -2
x = -2/(-1/3)
x = -2 * -3/1
x = 6.....so x intercept is (6,0)

so we need to find the graph that has a x intercept of (6,0) and a y intercept of (0,-2)
does that help ? Can you find it or do you still need help ? It is not A or B....try again

Answer 5

let me see

Answer 6

its hard but is it d?

Answer 7

it is D

Answer 8

thank u

Answer 9

sure thing :)

Answer 10

can u help me with more please im going to post them seperately

you can post them here if you like...I don't mind

Answer 12

i can i closed it out though

Answer 13

will i get in trouble?

Answer 14

does not matter...I can answer on closed q's

Answer 15

k hold on u dont want more medals lol?

Answer 16

I do not do this for the medals

Answer 17

ok

Answer 18

maybe c

Answer 19

ok....notice that your equation is in point slope form....we want to put it in y = mx + b form.
y + 1 = 3/5(x - 3)
y + 1 = 3/5x - 9/5
y = 3/5x - 9/5 - 1
y = 3/5x - 9/5 - 5/5
y = 3/5x - 14/5

In y = mx + b form, the y intercept is in the b position. So our y intercept is (0,-14/5)....for graphing purposes, -14/5 is the same as - 2 4/5

to find x intercept, sub in 0 for y
0 = 3/5x - 14/5
-3/5x = -14/5
x = (-14/5) / (-3/5)
x = -14/5 * - 5/3
x = 70/15....for graphing purposes, that is 4 2/3

so we need to find the graph with x int (4 2/3,0) and y int (0,-2 4/5)
Its a little more difficult with fractions. Do you see a graph like that ?
Apparently you do because C is your answer

Answer 20

ya thanks

Answer 21

nice job :) you deserve a medal

Answer 22

thank u i need help with a few more u want to help me or do u want me to post them

Answer 23

I can try to help.....as long as its not geometry...not too good at that

Answer 24

umm i dont know what its called hold on

Answer 25

do i have to divide or something

Answer 26

cost = 3 + 0.25x ---- x stands for each 15 minute interval.

so if we sub in 3 for x...
cost = 3 + 0.25(3) = 3 + 0.75 = 3.75

and if we sub in 5 for x..
cost = 3 + 0.25(5) = 3 + 1.25 = 4.25

see how I am doing this....and this matches table B

Answer 27

oh ok thank u

Answer 28

your very welcome :)

Answer 29

u seem very nice and intelligent

Answer 30

I try :)

Answer 31

u want to help me more the next one is a graph

Answer 32

I can try

Answer 33

slope = (y2 - y1) / (x2 - x1)
(0,6)...x1 = 0 and y1 = 6
(40,4)...x2 = 40 and y2 = 4
now we sub and find the slope
slope = (4 - 6) / (40 - 0)
slope = -2/40
slope = -1/20.....or - 0.05

its gonna be A

Answer 34

4 more?

Answer 35

ask away

Answer 36

u r sooo nice u deserve medals im gonna post the rest k

Answer 37

its up to you

Answer 38

once u respond i will close it but do u want me to tag u?

Answer 39

not necessary...I will see your post

Answer 40

k
