2. Remove all opposites.
3. Add up all like terms.
4. Finish equation!
Sorry I wasn’t able to show you how I did it, but it’s hella hard to type out. Hopefully you got the concept and it helps. Good luck! :)
Answer:
16
Step-by-step explanation:
Answer:
The value of 4 is an input of the function
Step-by-step explanation:
Let
x -----> the independent variable or input value
y ----> the dependent variable or output value
we know that
Looking at the graph
The domain (input values) of the linear function is equal to the interval
[1,∞)
All real numbers greater than or equal to 1
The range (output values) of the linear function is equal to the interval
(-∞,3]
All real numbers less than or equal to 3
therefore
The value of 4 is an input of the function
Answer:3
Step-by-step explanation: difference means subtract so you subtract 12 and 9 which gives you 3.
Answer:
- 11 ≤ x ≤ - 3
Step-by-step explanation:
Inequalities of the type | x | ≤ a , have a solution of the form
- a ≤ x ≤ a
Then
| x + 7 | ≤ 4
- 4 ≤ x + 7 ≤ 4 ( subtract 7 from each interval )
- 11 ≤ x ≤ - 3
