Answer:

y = 4

Step-by-step explanation:

-3x - 9y =36

-9y = 36 + 3x

-9 = ( 36 + 3x ) ÷ 9

y = 4 + 3x

y = 4 + 3(0)

y = 4

Answer:

y = -4

Step-by-step explanation:

-3x - 9y = 36

if x = 0

-3x would have to equal 0

so 0 - 9y = 36

36 - 0 = 0

so 36 will have to divide by 9 which equals 4

and since it's 0 - 9y, the number will have to be negative. so it will be -4.

so 0 *-3x* - -36 *9y* = 36

= 0 + 36

= 36

amirah ,who is at a point P ,observes a boat at pont B 1200m from P in direction 047 degrees. The boat is moving due north of B

Luda [366]

Answer:

about 2.81 km/h

Step-by-step explanation:

It can be useful to draw a diagram.

The lines pointing to due north from points B and P are parallel, so the angle BCP and the bearing of point C from P are the same, 30°. The angle BPC will be the difference of bearings of B and C at P, so is 47-30=17°. This is enough information to solve the triangle using the Law of Sines:

PB/sin(C) = CB/sin(P)

CB = PB·sin(P)/sin(C) = (1200 m)·sin(17°)/sin(30°) ≈ 701.7 m

The speed of the boat is then ...

x = distance/time = (0.7017 km)/(1/4 h) = 2.8068 km/h
