Answer:
Step-by-step explanation:
x (3,7,11,15)
y (4,6,8,10)
A. This IS a function because u have no repeating x values
B. Data in table :
when x = 11, y = 8
relation : f(x) = 5x - 21....when x = 11
f(11) = 5(11) - 21
f(11) = 55 - 21
f(11) = 34.....so when x = 11, y = 34
therefore, the relation f(x) = 5x - 21 has a greater value then the table
C. f(x) = 5x - 21......f(x) = 99
99 = 5x - 21
99 + 21 = 5x
120 = 5x
120/5 = x
24 = x <====
40 miles per hour because 140 divided by 3.5 is 40.
Answer:
yes

Answer: it is 12 hours
Step-by-step explanation: hope it helps
Answer: They are wrong
Step-by-step explanation: x is given a value in the problem. Since x equals 4, We plug x into the equation.
y = 2(4) + 1
Y is actually equal to 9 minutes, not twelve.
