Answer:

  a) k = 2/5

  b) y = 2/5x

  c) y = 2 3/5

Step-by-step explanation:

<h3>a)</h3>

The proportional relation is described by the equation ...

  y = kx . . . . . . k is the constant of proportionality

The value of k can be found by dividing the equation by x:

  y/x = k = (2 1/4)/(5 5/8) = (9/4)/(45/8) = 18/45

  k = 2/5

__

<h3>b)</h3>

As above, the equation is ...

  y = kx

  y = 2/5x

__

<h3>c)</h3>

Using 6.5 for x, we have ...

  y = (2/5)(6.5) = 2.6 = 2 3/5

ddd [48]

Answer:

B = 15.1°, C = 34.9°, c = 39.6

Step-by-step explanation:

law of sines

53/sin 130 = 18/sin B

sin B = .26;   B = 15.1°

C = 180 - 15.1 - 130 = 34.9°

c/sin 34.9 = 53/sin 130

c = 39.6

9w-4w+6&lt;1+5w supposed to combine like terms
Mariana [72]

Answer/Step-by-step explanation:

Given:

9w - 4w + 6 < 1 + 5w

To solve, collect like terms.

Subtract 5w from both sides

9w - 4w + 6 - 5w < 1 + 5w - 5w

9w - 4w - 5w + 6 < 1

6 < 1 (incorrect)

The inequality given has no solution or an information is missing.

Un radar de l'armée américaine réussit à détecter tout ce qui se trouve à un rayon représenté
WARRIOR [948]

Répondre:

r <27

Explication étape par étape:

Compte tenu de l'inégalité 5r + 9> 10r - 126

Nous devons trouver l'ensemble de solutions

5r + 9> 10r - 126

Ajouter 126 des deux côtés

5r + 9 + 126> 10r - 126 + 126

5r + 135> 10r

5r-10r> -135

-5r> -135

Divisez les deux côtés par -5 (notez que le signe changera)

-5r / -6 <-135 / -5

r <27

Par conséquent, les ensembles de solutions sont des valeurs inférieures à 27
