Um i would need more details
But i thing you would add those together
In intercept form, the plane that has these intercepts is ...
... x/(x-intercept) + y/(y-intercept) + z/(z-intercept) = 1
... x/1 + y/(-1) + z/2 = 1
... 2x -2y +z = 2 . . . . . in standard form
Perform the indicated multiplications...
12x*x+12x*2-5*2x-5*(-1)
12x^2+24x-10x+5 combine like terms
12x^2+14x+5
X= 9 over 4 is the correct answer
Answer:
Jesse needs to work 43 hours in the month to make $400 and $60
work for answer: 9.50 x 43 = 408.5
