Let k, h be unknown constants and consider the linear system: -7x + 5y + 6z = -3 -19x + 9y + hz = k 6x - 2y - hz = 7This system has a unique solution whenever h is not equal to___.If h is the (correct) value entered above, then the above system will be consistent for how many value(s) of k? a. a unique value. b. no values. c. infinitely many values.

yes

Step-by-step explanation: idk idk idk idk idk SORRY LOL!

step-by-step explanation:

the orientation of the parabolas can easily be found by analysing the power of x and y and their signs. if x is squared , parabola opens up and also if its coefficient is negative it opens down. if y is squared , the parabola opens right and also if its coefficient is negative it opens left. however in order to do the above analysis our equation must be in standard form .

our parabola is

which is not standard form of any parabola . hence we square on both hand side and convert it into standard form.

hence we see that x is squared and its coefficient is non negative . there for it opens up.
