Answer:
Option B
Step-by-step explanation:
Again, another great question! Here we are given the following system of equations, bound by quadrant 1 -
Convert this to slope - intercept form -
Now the graphed solution of this intersects at a shaded region with which there are 3 important point that lie on the border. They are the following -
( 0, 10 ),
( 15, 9 ),
( 17, 0 )
When these point are plugged into the main function f ( x, y ) = 2x + 6y, the point ( 15, 9 ) results in the greatest solution of 84. Thus, it is our maximum point -
<u><em>Option B</em></u>
Answer:
245ft
Step-by-step explanation:
well, you can figure it out by substituting the x and y values into the equation and then solving
4=2(4)-4
4=8-4
4=4 so yes the point (4,4) does lie on the line y=2x-4
Answer:
f(3) = 3
Step-by-step explanation:
f(x) = 2x^2 – 5x
Let x = 3
f(3) = 2(3)^2 - 5(3)
= 2*9 -15
= 18-15
