The answer is B your welcome
Answer:
Domain: (-3, 7)
General Formulas and Concepts:
<u>Algebra I</u>
- Domain is the set of x-values that can be inputted into function f(x)
- Interval Notation - [a, b] is inclusive, (a, b) is exclusive
Step-by-step explanation:
According to the graph, our x-values span from -3 to 7. Since both are open dot, they are exclusive from the domain:
Interval Notation (-3, 7)
Inequality Notation -3 < x < 7
Answer:
32
Step-by-step explanation:
even numbers are 2,4,6,...,78
it is an A.P.
first term a=2
c.d. d=4-2=2
an=a+(n-1)d
78=2+(n-1)2
76=(n-1)2
n-1=76/2=38
n=38+1=39
now we take multiples of 10
10,20,30,...,70
70=10+(n-1)10
60=(n-1)10
n-1=60/10=6
n=6+1=7
so reqd. number of numbers=39-7=32
1. 1,728
2. You can't tell because it doesn't say the amount one serving will serve, and how many servings she is serving, and how many people come to her party. Sorry!!
I hope I helped with the first one!
