Answer:
y = -1/6x + 0
Step-by-step explanation:
Using the equation of line
y_2 - y_1 / x_2 - x_1 = y - y_1 / x_1
Using the information we are provided with
( -3, 0.5)(3 , -0.5)
y_1 = 0.5
x_1 = -3
x_2 = 3
y_2 = -0.5
-0.5 - 0.5 / 3- (-3) = y - 0.5 / x - (-3)
-0.5 - 0.5 / 3 +3 = y - 0.5 / x + 3
-1 / 6 = y - 0.5 / x + 3
Cross multiply
-1(x + 3) = 6(y - 0.5)
Open the brackets
-x - 3 = 6y - 3
-x - 3 + 3 = 6y
-x + 0 = 6y
Divide through by 6 to get y
Following the eqn y = mx + C
-x + 0 / 6 = 6y / 6
y = -x + 0 / 6
We can separate it
y = -x / 6 + 0/6
y = -1/6x + 0
Therefore, the equation of the line is
y = -1/6x + 0
Answer:
FOR H_2
Step-by-step explanation:
Given data:
concentration 
WE KNOW THAT
therefore
Now for conversion of mol to gram need the molar mass of element in which particular value convert to.
let us take 
we know that molar mass of is 2 gram
therefore
let take other example, for 
we know that molar mass of O_2 is 32 gram
therefore
Well it would be 3/15 but that simplified is 1/5 so the answer is 1/5.
3 1/5 / 9/10=?
16/5 / 9/10
16/5 x 10/9=160/45
160/45=32/9
32/9 or 3 5/9
Answer:
A Π B = [0,3)
be careful with the brackets :))
