5(x + y) - 3(x - y)

5x + 5y - 3x + 3y

5x - 3x + 5y + 3y

2x + 8y

5(x + y) - 3(x - y) = 2x + 8y

A manufacturer of bicycles has determined that 550 bikes per month will be sold at a price of $250. At a price of $150, it is es
iogann1982 [59]

750 bikes would be sold for $350

Let x represent the number of bikes sold per month and y represent the price.

550 bikes are sold at a price of $250, this can be represented by (550, 250). Also, 750 bikes is sold at a price of $150, hence it is represented by (750, 150)

A linear function is represented by:

y = mx + b

m is the slope, b is the y intercept.

Therefore the function is:

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-250=\frac{150-250}{750-550}  (x-550)\\\\y=\frac{1}{2}x-25

The number of bikes sold for $350 is:

350 = (1/2)x - 25

x = 750

Therefore 750 bikes would be sold for $350

The formula y = mx + b sometimes appears with


different symbols.


For example, instead of x, we could use the


letter C. Instead of y, we could use the letter F.


Then the equation becomes


F = mC + b.


All temperature scales are related by linear


equations. For example, the temperature in


degrees Fahrenheit is a linear function of degrees Celsius.

Water freezes at: 0°C, 32°F


Water Boils at: 100°C, 212°F


Hope this helps!
