Wittaler [7]3 years ago

Answer:

Step-by-step explanation:

For equating the equations, you get

 

x2 + kx - 3x + 4 = 0               eq1

 

 

Setting the derivative of f(x) equal to 3 yields

 

f'(x) = 3

 

2x + k = 3                           eq2

 

 

Now we substitute the value of k from eq2 into eq1.

 

x2 + x(3 - 2x) - 3x + 4 = 0

 

 

Solve for x from this equation.  Then plug in the value of x into eq2 to solve for k

mel-nik [20]

Answer:

So far we have looked at linear systems of equations in which the lines always intersected in one, unique point. ... When we graph them, they are one line, coincident, meaning they have all points in common. This means that there are an infinite number of solutions to the system.
