Answer:
7.5
Step-by-step explanation:
7.2 + 8.5 + 7.0 + 8.1 + 6.7 = 37.5
37.5÷5 = 7.5
(1,5) , (2,6) , (3,7) , (4,8) , (5,9)....these are the 5 points
x f(x)
1 5
2 6
3 7
4 8
5 9
domain (ur x values) is { 1,2,3,4,5}
range (ur f(x) or y values) is { 5,6,7,8,9}
Is ur relation a function : yes, it is a function. A function will not have any repeating x values. It can have repeating y values, just not the x ones.
Angle A = arctan(12/5) = 67.4 degrees
Angle A = arccos(5/13) = 67.4 degrees
yes the answer was the same
3x-y=12
3x-y-12=12-12
3x-y-12=0
