If ON= 5x - 7, LM = 4x+ 4, NM = x -7, and OL =3y-4, find the values of c and y for which LMNO MUST BE a parallelogram.

Sholpan [36]

Answer:

x=11, y=8/3

Step-by-step explanation:

Consider quadrilateral LMNO. If this quadrilateral MUST BE a parallelogram, then

LM=NO

and

LO=MN

Thus,

$\left\{\begin{array}{l}4x+4=5x-7\\ \\x-7=3y-4\end{array}\right.$

Solve this system of two equations. From the first equation:

$4x-5x=-7-4\\ \\-x=-11\\ \\x=11$

Substitute it into the second equation:

$11-7=3y-4\\ \\3y-4=4\\ \\3y=4+4\\ \\3y=8\\ \\y=\dfrac{8}{3}$

What is the value of sec theta given the diagram below?

marishachu [46]

Answer:

$\sec \theta=-\sqrt{5}$

Step-by-step explanation:

The hypotenuse is $h^2=6^2+3^2$

$h^2=36+9$

$h^2=45$

$h=\sqrt{45}$

$h=3\sqrt{5}$

The terminal side of $\theta$ is in the second quadrant.

In this quadrant; the secant ratio is negative.

$\sec \theta=-\frac{hypotenuse}{adjacent}$

$\sec \theta=-\frac{3\sqrt{5}}{3}$

$\sec \theta=-\sqrt{5}$

Debora [2.8K]

X = D/(1 - h)
1 - h = D/x
h = 1 - D/x

D = 400, X = 4000
h = 1 - 400/4000
h = 1 - 0.1 = 0.9

solniwko [45]

Answer:

b ≤ 26/3

Step-by-step explanation:

All we have to do is divide both sides by 3

3x/3 ≤ 26/x

x ≤ 8.67
