The point P(7, −3) lies on the curve y = 3/(6 − x). (a) If Q is the point (x, 3/(6 − x)), use your calculator to find the slope mPQ of the secant line PQ (correct to six decimal places) for the following values of x. (i) 6.9 mPQ = 1

The right answer is "3.33333".

Step-by-step explanation:

The given points in the question are:

Now,

The slope of PQ will be:

=

By putting the values, we get

=

=

=

=

=

hence,

x = 6.9

it's slope will be:

=

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
