Answer:

C) 4

Step-by-step explanation:

The point-slope equation of the line is ...

y -k = m(x -h) . . . . . line with slope m through point (h, k)

y +9 = 3(x -1) . . . . . line with slope 3 through point (1, -9)

For y=0 (the 0 of the function), we have ...

9 = 3(x -1)

3 = x -1

4 = x

The x-intercept is (4, 0).

Find the missing angle or side. Round to the nearest tenth.

babymother [125]

Answer:

$x = 19.4$

Step-by-step explanation:

For the 72-deg angle, 6 is the adjacent leg. x is the hypotenuse. The trig ratio that relates the adjacent leg to the hypotenuse is the cosine.

$\cos A = \dfrac{adj}{hyp}$

$\cos 72^\circ = \dfrac{6}{x}$

$x \cos 72^\circ = 6$

$x = \dfrac{6}{\cos 72^\circ}$

$x = 19.4$

Find the probability:

V125BC [204]

Answer:

There is a 2/6 chance

Step-by-step explanation:

Because there is only 6 possibilities on a die, under the conditions (even number or a number greater than 3), there are 4 possibilities. This makes a 4/6 chance which can be simplified to 2/6.

If NQZ ~ CBK, find BK

exis [7]

Answer:

Step-by-step explanation:

if they are similar their sides are in proportion and so are the corresponding medians

to see their corresponding sides line up the names of the triangles

N Q Z

⇵⇵⇵

C B K

BK / QZ = 45/27 ; substitute whit what you see in the picture

(4x+1) / (2x+7) = 45/27 ; cross multiply

27( 4x+1) = 45( 2x+7) ; distribute

108x + 27 = 90 x + 315; subtract 90x and 27 from both sides

108x -90x = 315 -27; combine like terms

18x = 288; divide both sides by 18

x=16

BK = 4* 16 +1 = 65
