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:
5500
Step-by-step explanation:
5000 + (10 / 100) x 5000 = 5000 + (1/10) x 5000 = 5000 +500= 5500 people visted the book fair in the second week

Answer:
Becky needs approximately 3 containers to fil the vase up to 75%.
Step-by-step explanation:
In order to solve this problem we first need to calculate the volume of the container as shown below:
volume = pi*r²*h = pi*5²*10 = 250*pi = 785 cm³
Since becky wants to fill 75% of the vase capacity, she needs to fill:
goal = 2800*75/100 = 2100 cm³
Therefore Becky needs a total of
containers = goal/volume
containers = 2100/785 = 2.67
Becky needs approximately 3 containers to fil the vase up to 75%.
