Answer:
Step-by-step explanation:
We can use the quadratic formula or factor, This looks hard to factor so we should use the quadratic formula.
ax^2 + bx + c
so
a=4
b=-9
c=2
you can try it by hand or use this:

you get x=2 and x=0.25 these are the x intercepts (where Y is zero and where the graph crosses the x axis)
so mark x=2 and x=0.25 with a dot on a number line and you can draw a straight line between them since that is the part of the graph that is below the x axis (because the equation has <0) it is a positive parabola because the "a" value is positive and the presence of a "b" value means part of the graph will be below the x axis
Answer: $27.50
Explanation:
4 students + 8 friends = 12 people altogether

Answer: B) 1/2
There are six sides labeled 1,2,3,4,5,6. We want values that are less than 4, so we want values from the set {1,2,3} which represents half of the list. In other words, we have 3 ways of getting what we want (1 or 2 or 3) out of 6 ways total (1,2,3,4,5,6) to have 3/6 = 1/2
