Answer:
The answer is option 2.
Step-by-step explanation:
You have to substitute the expressions into x :
h(x) = x + 4
h(x - 3) = (x - 3) + 4
h(x - 3) = x - 3 + 4
h(x - 3) = x + 1
11 is the correct answer.
6/3=2
2+9=11
Answer:
x ≈ 34.9
Step-by-step explanation:
Using the sine ratio in the right triangle
sin35° = 
= 
Multiply both sides by x
x × sin35° = 20 ( divide both sides by sin35° )
x= 
≈ 34.9 ( to the nearest tenth )
Do we have a model, or anything to go by?
Answer:
Sometimes
Step-by-step explanation:
I’ll give you an example so you can understand:
Let’s say x is 4. So plug 4 into the problem:
|4|=4 → This is a very true statement, where the absolute value of 4 is equal to 4.
Now, let’s say x is -7. So plug -7 into the problem:
|-7|=-7 → This is a false statement because it’s saying that the absolute value of -7 is -7 which is very untrue.
So |x|=x only works for positive numbers, but not negative numbers. Therefore, |x|=x is the absolute value of x <u>sometimes.</u>
