The supply curve for steel is 90x−y=−50. The demand curve is 10x+y=200. x is quantity in thousands of metric tons y is price in
ivolga24 [154]

Answer:

The intersection point of the two curves is (x,y) = \left(\frac{3}{2}\,kton.m, 185\,USD \right).

Step-by-step explanation:

From statement we get the following equations:

Supply curve

90\cdot x - y = -50 (1)

Demand curve

10\cdot x + y = 200 (2)

Where:

x - Quantity, measured in thousands of metric tons.

y - Price, measured in US dollars per metric tons.

If we add both equations, then we find that quantity is:

(90\cdot x -y )+(10\cdot x +y) = -50+200

100\cdot x = 150

x = \frac{3}{2}\,kton.m

Then, we finally find the price by substituting on (2):

y = 200-10\cdot \left(\frac{3}{2} \right)

y = 200-15

y = 185\,USD

The intersection point of the two curves is (x,y) = \left(\frac{3}{2}\,kton.m, 185\,USD \right).

Can someone help me thanks
Helga [31]

Answer:

-142

Step-by-step explanation:

So we have the function:

f(x)=-x^2-9x+20

To find f(9), substitute x for 9:

f(9)=-(9)^2-9(9)+20

Square the first term and multiply the second:

f(9)=-81-81+20

Add:

f(9)=-142

And that's our answer :)
