Just need help with 2 and 4 :)
vesna_86 [32]
2.)

0 = 6x + 3y +9
-3y = 6x + 3y - 3y +9

\frac{ - 3y}{ - 3}  =  \frac{6x + 9}{ - 3}  \\  \\ y =  - 2x - 3
By isolating y we now have the equation in slope intercept form:
y = mx + b

Where m = slope and b = y- intercept. Therefore, the slope is -2 and the y - intercept is -3.

4.)

Similarly, #4 is already in slope intercept form so we can solve it by inspection. So for #4 the slope is -1 and the y - intercept is 2.

Use the image below to answer the following question. Find the value of sin x® and cos yº What relationship do the ratios of sin
Flauer [41]

Answer:

sin(x) and cos(y) are equal and have ratio of 1 : 1

First find the missing hypotenuse using Pythagoras theorem:

a² + b² = c²

12² + 5² = c²

c = √144+25

c = 13

using sine rule:

sin(x) = \dfrac{opposite}{hypotenuse}

sin(x) = \dfrac{5}{13}

using cosine rule:

cos(y) = \dfrac{adjacent}{hypotenuse}

cos(y) = \dfrac{5}{13}
