Acompany produces accessories for smart phones and tablets. the profit on each smart phone case is $2 and the profit on each tablet case is $3. the company made a profit of $1,200 on the cases last month. the equation 2x + 3y = 1,200 represents the company's profit from cases last month, where x is the number of smart phone cases sold and y is the number of tablet cases sold.

2.describe how you would graph this line using the slope-intercept method. be sure to write in complete sentences.

2 x + 3 y = 1,200
3 y = - 2 x + 1,200   /:  3
The slope-intercept form of the equation is:
y = - 2/3 x + 400
0 = -2/3 x + 400
2/3 x = 400
x = 600
Therefore y-intercept is ( 0, 400 ) and x-intercept is ( 600, 0 )

Draw a line passing through the points : ( 0, 400 ) and ( 600, 0 ).

A) h(x) = f(x) +g(x)
.. h(x) = (5x +15) +(4x +20)
.. h(x) = 9x +35

b) f(4) = 5*4 +15 = 35
.. h(4) = 9*4 +35 = 71
If Frank gets half their combined pay for working the same time period, he makes more money by splitting with Gertrude (who loses money in the deal).


Frank breaks even in the team by working 5 hours. When he works more time than that, he's better off by himself. (The reverse is true for Gertrude.)
