Answer:
X = 3
Step-by-step explanation:
first you would do 2 * 5x - 2 * 7 = 2x+10
second you'll get 10x- 14 = 2x + 10
third subtract the 2x by the 10x
fourth you'll get 8x
fifth then add the 14 to the 10
sixth 8x = 24
divide that by 8x to both sides
so then you get x=3
Answer:
9 and -9
They would have to look like this: -|9| and -|-9|
The graph of f(x) = sqrt( 4x) looks like this. So choose the one that looks like the image attached.
Answer:
H1 : μ < 1225
Step-by-step explanation:
The alternative hypothesis in carrying out a statistical test could be explained as a notion which aims to displace or rival an initial position, the null hypothesis.
When declaring an hypothesis, the statement compares the initial or population mean in the hypothesis statement and not the result or outcome of the sample statistic.
In the scenario above :
The null is of the notion that :
H0 : μ = 1225 ;
Hence, the stance of the alternative which is that the mean is lower or less will be written as :
H1 : μ < 1225
3x - 3 = 2x
Add 3 on both sides
3x - 3 + 3 = 2x + 3
3x = 2x + 3
Subtract 2x on both sides
3x - 2x = 2x + 3 - 2x
3x - 2x = 3
x = 3
So, your final answer is x = 3.
