6. Solve each equation algebraically. What are the restrictions on the variables?
a) 5x + 11 = x + 5
b) x + 3 = V2x - 7
c) V13 - 4x = 2 - x
d) x + V-2x + 9 = 3
7. Solve each equation algebraically and
graphically. Identify any restrictions on
the variables.
a) V8 - x = x + 6
b) 4 = x + 2x - 7
c) V3x² – 11 = x + 1
d) x = V2x² - 8 + 2

then say something, tell them they won’t respect you if you don’t even have respect for your self sweetheart you need to lay it on them, all of it : )

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
