Secant Lines. A secant line is a line that intersects a circle at two points. Every secant line, therefore, contains a chord of the circle it intersects.

If MP = 6x – 5, QR = 3x + 1, and RN = 6, what is QN?

NeTakaya

Answer:

19 units.

Step-by-step explanation:

Consider the below figure attached with this question.

From the below figure it is given that MN=PQ.

It is given that MP = 6x – 5, QR = 3x + 1, and RN = 6.

Since non parallel sides are equal, therefore it is an isosceles trapezoid.

The diagonals of an isosceles trapezoid are equal.

$MP=QN$

$MP=QR+RN$

Substitute the given values.

$6x-5=3x+1+6$

$6x-5=3x+7$

$6x-3x=5+7$

$3x=12$

$x=4$

The value of x is 4.

$QN=MP=6x-5=6(4)-5=24-5=19$

Hence, the measure of QN is 19 units.

Agata [3.3K]

Answer:

${ \tt{ \frac{56}{44.8} = \frac{35 }{(x + 4)} }} \\ \\ { \tt{56(x + 4) = 35 \times 44.8}} \\ \\ { \tt{56x + 224 = 1568}} \\ \\ { \tt{56x = 1344}} \\ \\ { \tt{x = \frac{1344}{56} }} \\ \\ { \tt{x = 24}}$

If f(x)= -6x+6 then f^-1(x)=

drek231 [11]

Recall that, to get the inverse relation of any expression, we start off by doing a quick switcharoo on the variables, then we solve for "y".

$\bf \stackrel{f(x)}{y}=-6x+6\qquad inverse\implies \boxed{x}=-6\boxed{y}+6
\\\\\\
x-6=-6y\implies \cfrac{x-6}{-6}=y\implies -\cfrac{x}{6}+1=\stackrel{f^{-1}(x)}{y}$
