Fill in the blank so that the ordered pair is a solution of the question y=15-3x; (__,6)

3

Step-by-step explanation:

Plug in 6 for the y value. Solve for x.

x=3 (3,6)

Step-by-step explanation:

Y = 15 - 3x

Y = 6

6= 15-3x

-15 from each side

-9 = -3x

devide each side

ny -3

x=3

(check)

15-3(3) = 6

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
