What impact did Buzz Aldrin have on future space exploration?

Step-by-step explanation:

He pioneered underwater training techniques to simulate spacewalking. In 1966 on the Gemini 12 orbital mission, Buzz performed the world's first successful spacewalk – extra-vehicular activity (EVA), and set a new EVA record of 5 1⁄2 hours. During that mission he also took the first 'selfie' in space

answer: ur v dumb

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
