Dividing the first equation by 2
X + 2y = 12
Dividing the equation 2 by 4
-3x + 2y = -4
subtracting both equations
4x = 16
X = 4
Also 4 + 2y = 12
2y = 8
Y = 4

Answer:
f(x) = 10x + 13
Function f(7) = 83
Step-by-step explanation:
y = 10x + 13
f(x) = 10x + 13
Function f(7) = 10(7) + 13
Function f(7) = 83

Answer:
√27
Step-by-step explanation:
√9, √36, and √81 are rational
V initial = 0
v final = 1920 m/s
t = 3 2/3 mins = 220s
d = ?
d = 1/2(vi + vf)t
d = 1/2((0)+(1920))(220)
d = 211200m
