- 8x + 4 ≤ 36
Subtract 4 from both sides.
-8x ≤ 32
Divide both sides by -8.        When dividing by a negative number change the
 x ≥  - 4                                   inequality sign.

Uma loja de brinquedos tem uma vitrine com várias prateleiras contendo 21 bonecas, 18 carrinhos de brinquedo e 15 bonecos de açã
zaharov [31]

Responder:

3

Explicação passo a passo:

Dado :

Total de brinquedos:

Bonecas = 21

Carros Roy = 18

Figuras de ação = 15

Número total de brinquedos = (21 + 18 + 15) = 54 brinquedos

Número de brinquedos por prateleira = 18

Número de prateleiras:

Número total de brinquedos / número de brinquedos por prateleira

Número de prateleiras = 54/18

Número de prateleiras = 3

3 prateleiras estão na vitrine

If ED = 5y + 6 and DB = y + 30, find the value of y. Then find ED, DB, and EB.
Gemiola [76]

Answer:

Part 1) The value of y=6

Part 2) ED=36, DB=36 and EB=72

Step-by-step explanation:

In this problem we know that

ED=DB -----> equation A

EB=ED+DB -----> equation B

The point D is the midpoint ED

see the attached figure to better understand the problem

step 1

Find the value of y

Substitute the given values in the equation A

5y+6=y+30

solve for y

5y-y=30-6

4y=24

y=6

step 2

Find the value of ED,DB and EB

ED=5y+6

substitute the value of y

ED=5(6)+6=36

Remember that

ED=DB

therefore

DB=36

Find the value of EB

EB=ED+DB

EB=36+36=72

Please show that;<br><br> Sin(x+y)cos(x-y) = sin x cos x + sin y cos y
bulgar [2K]

Apply the rules of sum/difference for trigonometric functions:

\sin(x+y) = \sin(x) \cos(y) + \cos(x) \sin(y)

\cos(x-y) = \sin(x) \sin(y) + \cos(x) \cos(y)

Multiply the two expressions:

(\sin(x) \cos(y) + \cos(x) \sin(y)) (\sin(x) \sin(y) + \cos(x) \cos(y)) =

\sin(x) \cos(y)\sin(x) \sin(y) + \sin(x) \cos(y)\cos(x) \cos(y) + \cos(x) \sin(y)\sin(x) \sin(y) + \cos(x) \sin(y)\cos(x) \cos(y) =

\sin^2(x) \cos(y)\sin(y) + \sin(x) \cos^2(y)\cos(x)+ \cos(x) \sin^2(y)\sin(x) + \cos^2(x) \sin(y)\cos(y)

You can factor \cos(y)\sin(y) from the first and last term, and \sin(x)\cos(x) from the two middle terms: you have

\cos(y)\sin(y)(\sin^2(x)+\cos^2(x)) + \sin(x) \cos(x)(\cos^2(y)+\sin^2(y))

Since \sin^2(x)+\cos^2(x)=1, the identity is proven.
