Answer: x=-8 and y=9
Step-by-step explanation:
3x +4y=12 ( This can be equation 1)
-3x-2y=6 ( This can be equation 2)
Equation 1 + equation 2 = 2y=18
y= 18÷2
y=9
Substitute 9 for y in 3x+4=12
3x+4y=12
3x+4(9)=12
3x+36=12
3x= 12-36
3x=-24
x= -24÷3
x= -8
Therefore x=-8 and y=9

Answer:
ME = z*s /√n
Step-by-step explanation:
The margin of error is obtained as the product of the critical value of the distribution at a certain α-level and the standard error :
The critical value = Z*
The standard error = standard deviation / √sample size
Standard deviation = s
Sample size = n
Margin of Error = z * s/√n
The answer is -300

Answer:
A'(-4,4)
B'(-2,11)
Step-by-step explanation:
6 unit up and 3 unit left
A (-1,-2) : 6 unit up → (-1,4) → 3 unit left → (-4,4)
A'(-4,4)
B (1,5) : 6 unit up → (1,11) → 3 unit left → (-2,11)
B'(-2,11)
