Answer:
Line R
Step-by-step explanation:
X/5 = 8/9
this is a proportion, so we cross multiply
(9)(x) = (5)(8)
9x = 40
x = 40/9 or 4 4/9
So you want to make it: total distance (d) = rate (r) × total time (t), solving for r: r = d / t
r = (420mi) / (3h+214h), r = 420mi / 217h
r = 1.935mi/h = 1.94mi/h
Answer:
x=65
Step-by-step explanation:
solve for the angle not marked⇒ 180-147=33
add known angles⇒ 33+82= 115
subtract total known value from 180**⇒ 180-115=65
**all interior angles of a triangle must add up to 180°
Answer:
7-10. domain is all x, range is all y
11. just name all numbers other than 6, 8, and 10 (1, 2, 7, etc.)
12a. (-1,0), (-2,-1), (0,1) (1,2)
12b. Yes, none of the domains are the same and the ordered pairs listed above all follow the rules stated. If it did not follow the rules, the pair(s) would not be Relation B
Step-by-step explanation:
11: In order for relations to be functions, the "x" of the pair needs to be different from the rest. Having the same "x" as another ordered pair would not make it a function.
12a. Follow the rules they state, x ==> y (which I think means x is the number before y) and y > x, honestly not even sure if this is correct
12b. If x ==> was correct in my interpretation, then the ordered pairs I listed should all fit within the boundaries of what relation B would be defined as.
