For which of the following inequalities is x ≥ 5 a solution? 1. x + 5 ≥ 10
2. 5x ≥ 10
3. x - 5 ≥ 10

1

Step-by-step explanation:

if you were to solve for x you would get the same as because you would subtract 5 from each side and 10-5=5

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

6-3=3

3*3=9

9+12=21

21/3=7

7*8=56

56 is your answer
