Answer:
A, D
Step-by-step explanation:
for this table:
x 0 5 10 15 20 25 30 35 40
f(x) 5 6 7 8 9 10 11 12 13
A, assuming it's supposed to say f(5)=6, is true since 5 in x corresponds to 6 in f(x)
B is false, since the domain would be the set of all numbers in x, since domain corresponds to input (x) and range corresponds to output (f(x))
C is false, the range is not all real numbers since it is a defined set of numbers
D is true, since 15 in x corresponds to 8 in f(x)
Therefore, A and D are true

Try this Drag ... Alter the number of sides. ... If you know the apothem, or inradius, (the perpendicular distance from center to a side.
Missing: 6.8 | Must include: 6.8
Step-by-step explanation:
It is a 90° angle from up to right and 65 makes up part of it so 90-65=25
15X2+(14-3) IS THE ANSWER TO THE PROBLEM
First, you would have to make the number of hours the x value and total cost the y value in the graph. Then, you would take however many hours to replace x, let’s say 5, and replace it for x in the equation y=8x+12, giving you y=8*5+12. You would then solve it by multiplying 8 and the x value, 5, giving you 40 in this example, and then adding 12, giving you 52 dollars for 5 hours.
To draw the line on the graph, you would start 0 hours with 12 dollars, 1 hour for 20 dollars, 2 hours for 28 dollars, and so on, adding 8 each time you add an hour.
