Answer:
x is a variable, it can be ANY NUMBER
Step-by-step explanation:
Answer:

Step-by-step explanation:
The calculator approximated the value of y at 7.8.
We need to complete the error interval for y.
In other words, we calculate the upper and lower bound for y.
The level level of accuracy is to the nearest tenth.
To find the lower bound, we subtract half the degree of accuracy to get:

To find the upper bound, add half the level of accuracy to get:

Therefore the error interval is

Answer: 1
Step-by-step explanation:
-11, -7, -3...
you add 4 each time so the next number would be 1
X = 47°
y = 90°
These are the angles, comment if you would like to know the explanation but these are the answers
Answer:
hello there
ok so the answer is 4 + 
Step-by-step explanation:
hope this helps!
