Point K is on line segment JL. Given KL = 2x – 2, JL = 4x + 9, and

sergeinik [125]

Answer:

JL = 21

Step-by-step explanation:

Given that K is on line segment JL, therefore:

KL + JK = JL (according to segment addition postulate)

KL = 2x - 2

JK = 5x + 2

JL = 4x + 9

Thus:

$(2x - 2) + (5x + 2) = (4x + 9)$

Solve for x

$2x - 2 + 5x + 2 = 4x + 9$

$2x +5x - 2 + 2 = 4x + 9$

$7x = 4x + 9$

Subtract 4x from both sides

$7x - 4x = 4x + 9 - 4x$

$3x = 9$

Divide both sides by 3

$\frac{3x}{3} = \frac{9}{3}$

$x = 3$

Find the numerical length of JL

$JL = 4x + 9$

Plug in the value of x

$JL = 4(3) + 9 = 12 + 9 = 21$

What is the period function of f(x)=1/2tan (2x+5)

soldi70 [24.7K]

Compare your f(x)=1/2tan (2x+5) to

g(x)=a*tan (bx + c).

Note how b = 2.

The period of the given tangent function is pi/b, which here is pi/2, or 90 degrees. Multiplying x by 2 horizontallyl compresses the graph of tan x by a factor of 1/2.

O GRAPHS, FUNCTIONS, AND SEQUENCES

WINSTONCH [101]

Always use the formula (y2-y1)/(x2-x1) to find a line’s slope, given two points:

(-1- -8)/(4-5) = 7/-1 = -7

-7 is the slope
