2nd and 4th are functions
an x value in a set of functions can only have one y value. however, a y value can have infinite amount of x values
in the 1st and 3rd set, the x value of -2 has 2 y values
Answer:
22 people saw an horror movie
Step-by-step explanation:
Total people who attended the Sunday matinee = 48
People who saw romantic comedy = 3/8 of 48
= 3/8 × 48
= (3*48) / 8
= 144 / 8
= 18 people
People who saw action movie = 1/6 of 48
= 1/6 × 48
= 48/6
= 8 people
People who saw horror movie = x
Total people who attended the Sunday matinee = People who saw romantic comedy + People who saw action movie + People who saw horror movie
48 = 18 + 8 + x
48 = 26 + x
Subtract 26 from both sides
48 - 26 = 26 - 26 + x
22 = x
x = 22 people

Step-by-step explanation:
8 : 10
4 : 5
hope this was helpful : )
y=4x-6.....(1)
5x+3y=1....(2)
substitute y=4x-6 into equation 2
5x+3(4x-6)=1
5x+12x-18=1
17x=19
x=1.12
substitute x=1.12 into equation 1
y=4(1.12)-6
y=4.48-6
y=-1.52
x=1.12,y=1.52
Answer:
x>1 (the first one)
