There are 2 tangent lines that pass through the point
and
Explanation:
Given:
The point-slope form of the equation of a line tells us that the form of the tangent lines must be:
For the lines to be tangent to the curve, we must substitute the first derivative of the curve for :
Substitute equation [2] into equation [1]:
Because the line must touch the curve, we may substitute
Solve for x:
±
± <em> </em>
There are 2 tangent lines.

Answer: 45r
Step-by-step explanation:
X = first venture, y = second venture, z = third venture
x + y + z = 15,000
x + z = y + 7000
3x + 2y + 2z = 39,000
these are ur equations.....
x + y + z = 15,000
x - y + z = 7000
--------------------add
2x + 2z = 22,000
x + y + z = 15,000....multiply by -2
3x + 2y + 2z = 39,000
-------------------
-2x - 2y - 2z = - 30,000 (result of multiplying by -2)
3x + 2y + 2z = 39,000
------------------add
x = 9,000
2x + 2z = 22,000
2(9000) + 2z = 22000
18,000 + 2z = 22000
2z = 22000 - 18000
2z = 4000
z = 4000/2
z = 2,000
x + y + z = 15,000
9000 + y + 2000 = 15,000
11,000 + y = 15,000
y = 15,000 - 11,000
y = 4,000
first venture (x) = 9,000 <==
second venture (y) = 4,000 <==
third venture (z) = 2,000 <==
Answer:
y= -5
