3x - 8 = -2 |subtract 10 from both sides
3x - 18 = -12 |divide both sides by 3
x - 6 = -4
Answer:
The answer to your question is C. 3.2
Step-by-step explanation:
| 3.2 |
lines | | mean absolute value, and absolute value means the distance of a number to the origin (0,0) it does not matter the sign.
Then to answer your question just do not write the | | and consider it as a positive sign.
If your question had a negative number ex. | -3.2 | the answer would also be 3.2.

Answer:
The area to the right of 2.120 is 0.0250 rounded to 4 decimal places
Step-by-step explanation:
We are required to find 
To find this area we have to use the t distribution. Also we can use technology like excel to find the area to the right of 2.120.
The excel function is:
=TDIST(2.120,16,1)=0.0250
Where:
2.120 is the value of the test statistic
16 is the degrees of freedom
1 denotes the one tailed.
Therefore, the area to the right of 2.120 is 0.0250
Answer:
See below.
Step-by-step explanation:
Use the same method as before. Go from each original point in a direction perpendicular to the line of reflection, and then go the same distance to the other side of the line.
If y=8-x then you can plug that into the equation like 7=2-(8-x). When you distribute the equation becomes 7=2-8+x. Once you combine like terms the equation becomes 7=-6+x. Then you subtract 6 from both sides, which gives you 13=x.
To find y just put 13 where x was in the first equation. Y=8-13.
Y=-5
X=13
