Answer:
Step-by-step explanation:
Are you certain you wrote the question accurately?—because none of the choices is correct.
rearrange 3x+y =-5 to solve for y:
y = -3x-5
substitute -3x-5 for y into the second equation:
12x + 3y = 13
12x + 3(-3x-5) = 13
12x - 9x - 15 = 13
3x = 28
x = 28/3
y = -3x-5 = -33
solution: (28/3, -33)
If the first term of the function is negative then the parabola will open down and it has a maximum value.
If the first term of the function is positive then the parabola will open up and it has a minimum value.
In the case of your example the parabola will open down and will have a maximum value.
hope this helps :)
Y=3x-9
So when x is 16
Y=3(16)-9
Y=48-9
Y=39
The answer is c
