Answer:

y=2x-6

Step-by-step explanation:

y+4=2(x-1)

Subtract 4 to both sides of the equation:

y+4-4=2(x-1)-4

y=2(x-1)-4

Distribute the 2:

y=2x-2-4

y=2x-6

Where 2 is the slope and -6 is the y - intercept.

Solve, graph, and give interval notation for the inequality:

Georgia [21]

Answer:

The answer to your question is

Step-by-step explanation:

Inequality 1

4(3x - 4) < 32

12x - 16 < 32

12x < 32 + 16

12x < 48

x < 48/12

x < 4

Inequality 2

2x + 1 ≤ 8x + 25

2x - 8x ≤ 25 - 1

- 6x ≤ 24

x ≥ 24/-6

x ≥ - 4

- See the graph below

- Interval [-4, 4)

I need step by step explanation and answer please

fredd [130]

Answer:

Step-by-step explanation:

Trigonometric identities:

$\sin^{2} (x) + { \cos}^{2} (x) = 1 \\ {\cos}^{2} (x) = 1 - { \sin}^{2} (x) \\ { \sin }^{2} x = 1 - {\cos}^{2} (x) \:$

Replace into the equation

$\frac{ \sqrt{1 - \cos^{2} (x) } }{ \sin(x) } + \frac{ \sqrt{1 - \sin^{2}(x) } }{ \cos(x) } \\ \\ = \frac{ \sqrt{ \sin^{2}(x) } }{ \sin(x) } + \frac{ \sqrt{ \cos^{2}(x) } }{ \cos(x) }$

Remove roots and simply

$= \frac{ \sin(x) }{ \sin(x) } + \frac{ \cos(x) }{ \cos(x) } \\ \\ = 1 + 1 \\ = 2$

Find the length of . Use that length to find the length of .

Verdich [7]

Answer:

Length of CD is 10.7 cm

Step-by-step explanation:

we are given to find length of CD

Calculation of CD:

Firstly, we will find AC

In triangle ABC, we can use trig

$sin(30)=\frac{AC}{10}$

$AC=10sin(30)$

$AC=5$

now, we can find CD

In triangle ACD , we can use trig

$cot(25)=\frac{CD}{AC}$

$CD=ACcot(25)$

now, we can plug AC=5

$CD=5cot(25)$

$CD=10.7$
