X-intercepts are points where the graph intersects the x-axis, i.e. when y=0.
Substitute y=0 and solve for x:
y=x^2-3x+2
0=x^2-3x+2
0=(x-2)(x-1)
By the zero product property, we deduce x-2=0 or x-1=0, i.e. x=1 or x=2.
6636 has 3 circle so 6636=3
8118 has 4 circle so 8118=4
2212 has 0 circle so 2212=0
8688 has 7 circle 8688=7
5971 has 1 circle 5971=1
Answer:
6x + 25 ≤ 135
Step-by-step explanation:
Maximum amount to spend = $135
Boxes of popcorn = 2
Boxes of candy = 3
Cost per box of popcorn = $6
For 3 boxes = $6 * 3 = $18
Cost per box of candy = $3.50
For 2 boxes = $2 * 3.50 = $7
Item cost = Cost of candy and popcorn = $18 + $7 = $25
Ticket price = $6
Inequality to find number of friends ;
Let number of friends = x
Ticket cost = 6x
Hence ;
Ticket cost + item cost ≤ 135
6x + 25 ≤ 135
