Answer:

8x - 15

Step-by-step explanation:

Evaluate g(2x) then use the value obtained to evaluate g(x) , that is

g(2x) = 2(2x) - 5 = 4x - 5 , then

g(4x - 5) = 2(4x - 5) - 5 = 8x - 10 - 5 = 8x - 15

Answer:

$12\sin{(2\theta)}\cos{(\theta)}$

Step-by-step explanation:

The appropriate trig identity is ...

$\sin{a}+\sin{b}=2\sin{\left(\dfrac{a+b}{2}\right)}\cos{\left(\dfrac{a-b}{2}\right)}$

Here, you have a scale factor of 6 and a=3θ, b=θ. Filling in these values gives ...

$6\sin{3\theta}+6\sin{\theta}=12\sin{\left(\dfrac{3\theta+\theta}{2}\right)}\cos{\left(\dfrac{3\theta-\theta}{2}\right)}\\\\=12\sin{(2\theta)}\cos{(\theta)}$

In the figure below, segment CD is parallel to segment EF and point H bisects segment DE :

Grace [21]

Answer:

See explanation

Step-by-step explanation:

In the figure below, segment CD is parallel to segment EF, DE is a transversal, then angles DIH and HGI are congruent as alternate interior angles when two parallel lines are cut by a transversal.

Consider triangles DIH and EGH. In these triangles,

$\angle DIH\cong \angle EGH$ as alternate interior angles;
$\angle DHI\cong \angle GHE$ as vertical angles;
$DH\cong HE$ because point H bisects segment DE (given).

Thus,

$\triangle DIH\cong \triangle EGH$ by AAS postulate

What is the slope in slope-intercept form for this graphs?

s2008m [1.1K]

Answer:

Step-by-step explanation:

since the line crosses the y axis at -4 we know that b in the slope intercept form is -4 . now we just need the slope.. and slope is rise over run or y/x... soooo .....

looking at the graph I see that the point (-1,4) and (0,-4) look like they are points on the graph..

soooo....

the rise is -8 when the run is 1 or -8/1 or just -8

use the slope intercept form y = mx + b

y= -8x + (-4)

y = -8x -4 :)
