Given:
mean = 64
standard deviation = 6
sample size = 50
Standard error of the sample mean = standard deviation / √sample size
Standard error = 6 / √50 = 6/7.07 =<span> 0.85</span>
First of all, the first power of 'x' is the highest power in the whole equation,
so we only expect one solution.
You said that <span><u>3x+9 = 21+7x </u>
Subtract 3x from each side:
9 = 21 + 4x
Subtract 21 from each side:
-12 = 4x
Divide each side by 4 :
<u>-3 = x </u>

Answer:
Step-by-step explanation:
g(x) is the translation of the parent function f(x) to left by 1 unit and slightly stretched vertically.
<u>g(x) is:</u>

Answer: -y=7
Explanation:
Think of your problem as subtraction:
2x-3y+15
-2x+3y=-1
