Question

Your weight lifting class cost you a $20 fee up front and $5.50 per class after. The equation for this situation is y = 5.5x + 20. Make a T-table for the equation, using the x values 0, 10, and 20. Which ordered pairs are represented in your T-table?
A. (0, 0), (10, 55), (20, 110)
B. (0, 0), (55, 10), (110, 20)
C. (0, 20), (10, 75), (20, 130)
D. (20, 0), (75, 10), (130, 20)

Answer 1

Can anyone help

Answer 2

all you really have to do is plug these x values into the equation given

Answer 3

So just see if they add up

Answer 4

yea.. the answer you get would be your y coordinate

Answer 5

So if I did it correct I got A as my answer

Answer 6

is that right

Answer 7

not quite

Answer 8

Oh, do I have to add the 20 also

Answer 9

yup

Answer 10

so C

Answer 11

yup^^

Answer 12

Thank you, can you show me how to do this one also-Write the equation y - 2 = 4(x + 5) in standard form.
A. 4x + y = 7
B. 4x - y = 3
C. 4x - y = -22

Answer 13

standard form of a line =Ax+By=C

Answer 14

take the first equation you have and simplify it

Answer 15

so take 4x+By=7

Answer 16

not quite.. take y-2=4(x+5) and simplify
you would get?

Answer 17

y-2=4x+20

Answer 18

alright subtract the two on both sides

Answer 19

y=4x-18

Answer 20

y=4x+22

Answer 21

sorry i meant add..

Answer 22

ok, so 4x-y=22

Answer 23

-22

Answer 24

yep, I forgot the -

Answer 25

thank you
