Answer:
-3 < x ≤ 7
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We can see from the graph that our x-values that can be inputted are from -3 to 7. Since -3 is an open dot, we cannot include this in our domain.
∴ -3 < x ≤ 7

30x=40(x-1)
30x=40x-40
40=40x-30x
40=10x
x=4
Answer:
Step-by-step explanation:
we know that
The scale on the map is equal to
so
by proportion
Find the distance on the map from Catskills to Saugeties
(6 • 2 - 2x + 16) + (4 • 2 + 7x - 55)
(-2x + 16 + 6 • 2) + (7x - 55 + 4 • 2)
(-2x + 16 + 12) + (7x - 55 + 8)
-2x + 28 + 7x - 47
-2x + 7x + 28 - 47
5x + (-19)
5x - 19
So the answer is 5x - 19.
Cross multiply: 60%/100% =21/x
X is the variable we are trying to find.
100*21=2,100
2,100/60
X =35
All together in the choir there are 35 members.
I hope this helps!
