Answer: below i've attached a file that you view for ---> 4x-3y=1 and 3y=x-1 using the substitution method (please let me know if you can see it ..you might need to zoom in )
Step-by-step explanation:
Answer:
Their were 42 kids on each bus.
Step-by-step explanation:
You have to divide the number of kids(210) by the number of buses.
3H2 +N2 ----> 2NH3
3 mol 2 mol
21.0 mol x mol
x=21.0*2/3=14.0 mol NH3
Answer:
y = negative 1 over 2x + 11
Step-by-step explanation:
Given the table :
X - - - - Y
2 - - - - 10
4 - - - - 9
6 - - - - 8
8 - - - - 7
The equation can be modeled using the equation of a line or linear equation and obtaining the equation of the best fit
y = mx + c
x and y are the variables
m = slope or gradient of the line
c = intercept
The equation can be obtained by using the linear regression calculator, Inputting the x and y values which yields the equation of the best fit line.
The result obtained from the calculator is:
ŷ = -0.5X + 11
