Answer:
A shaded region below a dashed line (y <3x-4)
Step-by-step explanation:
For linear inequalities, we have shaded regions below or above a dashed or solid or continuous line represented by an inequality.
Their graphs are called region graphs. Those regions are only enclosed ones if before the sign of inequality it is included both variables. Like x²+y²<1, |x+y|<1, etc.
In this case what we have here is an open region, as the graph below shows.
3x-y>4 =-y>4-3x∴y<3x-4
Setting a value for x
3x-4=0
3x=4
3x/3=4/3
x=4/3 (slope)
(4/3,0)
Answer:
11
Step-by-step explanation:
there are 11 spaces between the points
just count the number of spaces, no calculations needed.
Answer:

Step-by-step explanation:
we know that
Using proportion

Okay so...
There are 21 groups of 3.
21 x 3 = 63.
63 people are in the room.
