Which equation represents the linear relationship shown in the table? y=3x+4 y=3x+8 y=8x+3 y=4x+3 x y 0 3 2 11 4 19 6 27

Answers

Answer:

The linear relationship is given by,  y = 4x + 3

Step-by-step explanation:

The points given are ( as (x,y) pair)

x     y

0      3

2     11

4     19

6     27

The given lines are ,

1) y = 3x + 4

2) y = 3x + 8

3) y = 8x + 3

4) y = 4x + 3

Now , by inspection or trial and error method only line (4) does satisfy all the points, so the linear relationship is given by,

y = 4x + 3

If 3x-7=5t what is 6t?

Answers

so one easy way is
divide both sides by 5
(3x-7)/(5)=t
multiply both sides by 6

 (6)/(1) times ((3x-7))/(5)=6 times t or

(6 times (3x-7))/(5)=6t or
(18x-42)/(5)=6t
