(5, 12) e (-10, -3)
x.......y...1
5.....12..1
-10..-3..1
12x -10y -15 + 120 -5y + 3x = 0
12x + 3x - 10y - 5y - 15 + 120 = 0
15x - 15y + 105 = 0 :(5)
3x - 5y + 21 = 0
m = -a/b
m = -3/-5
m(5) = 3/5
y-yo = m(x-xo)
y-14 = 3/5*(x-7)
y-14 = 3x/5 - 7/5
3x/5 - y + 14 - 7/5 = 0
3x/5 - 5y/5 + 70/5 - 7/5 = 0
3x - 5y + 70 - 7 =0
3x - 5y + 63 = 0
m(s) = -3/-5 = 3/5
m(r) = m(s) --> são paralelas
There is not a way to answer this because we don’t know what the graph you drew was.
The value of 
<u>Solution:</u>
Given: 
To find: The value of (h*h)(10)
We know that, 
which is,

On solving we get,

So, for x = 10 it will be,

Hence, the required value is 10.
Answer:
At break even cost = revenue
Step-by-step explanation:
A company is said to be at break even if the cost of producing an item is equal to the revenue generated from the sell of that item, that means there is no loss or gain.
If the cost function C(x) = 200 + 10x and the revenue function R(x) = 60x - x², where x is the amount of items produced. At break even, R(x) = C(x)
60x - x² = 200 + 10x
x² - 60x + 10x + 200 = 0
x² - 50 x + 200 = 0
x = 46 or x = 4 is the break even point
