Answer:
The Answer is D
Step-by-step explanation:
The answer is because the arrow is lowering down so it would be correct!
We are given with the formula
p = 200k - 500
a) The constraint for this formula is obtained from the idea that the profit must be positive
200k - 500 > 0
k > 500/200
k > 2.5
b) To make 14000 profit
14000 = 200k - 500
k = 72.5 or 73 knives must be sold
Step-by-step explanation:
1. convert the equation to its y = mx + b format. remember m is the slope (rise/run) and b is the y-intercept.
2. equation given: x + 2y = -6
bring x over to other side
3. now its looks like 2y = -6 - x
to get y by itself we need to divide by 2
4. now equation looks like y = -6/2 -x/2
we can reduce it so the final equation is
5. y = -1/2x - 3
this is in y=mx+b format. now its much easier to graph
6. the slope is -1/2 and the y-intercept is -3. put a point at (0,-3) and use the slope (-1/2) rise over run to get each point.
7. you move to the left because its negative
Since they both have 3x terms subtract the second from the first to get rid of the x terms...
3x+2y=10
-3x+y=-13
__________
3y=-3
y=-1, which makes 3x+2y=10 become: 3x-2=10 so
x=4
So the solution is the point (4, -1)
