Determine the rate of change for 3/2x -5/4y = 15

Aleksandr-060686 [28]

Answer:

-6/5

Step-by-step explanation:

3/2x - 5/4y = 15

-5/4y = -3/2x + 15

multiply each side by (-4/5)

(-4/5)(-5/4y) = (-4/5)(-3/2x + 15)

y = -6/5x - 12

rate of change: -6/5

PLEASEEE HELP Questions 4 and 5

Ilya [14]

Answer:

Given and explained below.

question 4

using sine rule:

$\sf sinx = \frac{opp}{hyp}$

$\sf sinx = \frac{11}{13}$

$\sf x = sin^{-1}(\frac{11}{13} )$

$\sf x = 57.8$

question 5

using cosine rule:

$\sf cosx =\frac{adj}{hyp}$

$\sf cos(31) =\frac{x}{17}$

$\sf cos(31)*17 =x$

$\sf x = 14.6$
