Answer:
Meryann brought 6 friends to the party
Step-by-step explanation:
y=9x+24
24 is your constant because the cost for all the pizza won't change
9x will change, so x represents the number of friends she brought
and y will be 78 because it's the total amount of money
78=9x+24
all you have to do is solve this equation
54=9x
x=6
The inequality shown by this graph is y ≥ 2.
<h3>Describe inequality.</h3>
the relationship between two non-equal expressions using a symbol like "not equal to," ≠ "greater than >," or "less than < "
The inequality sign : ≥ or ≤ to use is: or because the line is solid and not dotted.
Given that the points have y-coordinate values of 2, (-5, 2), and (3, 2), respectively, and that the line crosses the y-axis at this point, the proper inequality is:
y ≥ 2
Therefore, y ≥ 2 is the inequality.

t = time to hike up the hill
3-t is the time to hike down the hill
so 4t = 6(3-t)
4t = 18-6t
10t = 18
t = 18/10 = 1.8 hours to hike up the hill
1.8 hours = 1 hour 48 minutes
