Answer:
1st option: -2 < x ≤ 3
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We see that our x-values span from -2 to 3. Since -2 is an open dot, we cannot include it in our domain:
(-2, 3] or -2 < x ≤ 3
A line does not describe a slope.
Answer:
5:6 I think
Step-by-step explanation:
Let the required number be 'a'.
17 × a℅ = 20.4
17 × a/100 = 204/10
17a/100 = 204/10
17a = (204×100) /10
a = 20400 / 10 × 17
a = 20400 /170
a = 120
