Answer: The third and fourth problem are linear
Step-by-step explanation:
3rd problem follows a pattern
X 6 5 4 3
Y 21 15 10 6
6x3+3=21
5x3=15
4x2+2=10
3x2=6
Problem 4 follows a pattern as well
X value goes up 1, Y value goes up 4
Answer:
Step-by-step explanation:
If J can paint a room in 3 hours, in 1 hour she gets 
of the job done.
If A can paint a room in 4 hours, in 1 hour she gets 
of the job done. We need to find out how long it takes them if they paint together. The equation for this is:
where x is the number of hours it takes them to get the job done together. Multiply everything through by 12x to get
4x + 3x = 12 so
7x = 12 and
x = 1.7 hours to get the room painted together.
Answer: 1.875 is a rational number because it can be represented as a ratio or a fraction.
Answer: 8
Step-by-step explanation:

anything above 7 is correct
Answer:
17
Step-by-step explanation:
2c + d^3 - 3e +4f
=2(3) + (5^2) - 3(6) + 4(1)
=6+25-18+4
=17
