I need to find Y=Mx+b. I found M but i forgot how to find B. Help
enot [183]
Y = mx + b. This linear graph passes through A(0,50) and B(10,51)

m = (y₂-y₁)/(x₂-x₁)
m= (51-50)/10-0)
m=(1)(10)

y = (1/x) + b. To find b, you plugin the coordinates of either A or B,
say A(0,50):

50 = (1/10).(0) + b
50 = 0+b  and b= 51

Hence the equation is y =0.1x + 50

Given x(y + 2) = 3x + y, express y in terms of x.​
vodka [1.7K]

Answer:

y = \frac{x}{x-1}

Step-by-step explanation:

Given

x(y + 2) = 3x + y ← distribute parenthesis on left side

xy + 2x = 3x + y ( subtract 2x from both sides )

xy = x + y ( subtract y from both sides )

xy - y = x ← factor out y from each term on the left side )

y(x - 1) = x ← divide both sides by (x - 1)

y = \frac{x}{x-1}

Helens increases more over time
Clints salary increases 4000$ a year
Helens salary increases 5400$ a year
How i got that was i got there current wage subtracted it from there starting wage and then divided by 3 because it has been 3 years since the beginning wage
In 10 years if this rate continues clint would be makin 60,000$ for that year and helen would be makin 81,000$ for that year
