Answer:
I think the answer is B. Let me know if im wrong.
Step-by-step explanation:
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.
Answer:
y = -x + 9
Step-by-step explanation:
Since the line is parallel, the slope is -1.
y = -x + c
Substituting (0,9) into the above equation:
9 = 0 + c
c = 9
y = -x + 9

X = number of adult tickets
7x = value of the adult tickets
3x = number of child tickets
3x * 3 = value of children's tickets, which is also 9x
Value of adults plus value of children's = 6000
7x + 9x = 6000
Combine terms
16x = 6000
Divide by 16
x = 6000/16
Simplify fraction
x = 3000/8 = 1500/4 = 750/2 = 375 = number of adult tickets
Number of children's tickets = 3 * 375 = 1125 = number of children's tickets
Check:
Adults = 375 * 7 = 2625
Children's = 1125 * 3 = 3375
Total = 6000
Answer:
(c) f(g(3)) > g(f(3))
Step-by-step explanation:
The relationship between the function values can be found by evaluating the functions.
<h3>f(g(3))</h3>
The order of operations tells us we must first evaluate g(3).
g(x) = -3x +15
g(3) = -3(3) +15 = 6
Then we can evaluate f(x) for x=6:
f(x) = 7x
f(6) = 7(6) = 42
So, the composition is ...
f(g(3)) = 42
<h3>g(f(3))</h3>
As above, we must first evaluate f(3):
f(3) = 7(3) = 21
Then we can evaluate g(x) for x=21:
g(21) = -3(21) +15 = -63 +15 = -48
That means the composition is ...
g(f(3)) = -48
<h3>Comparison</h3>
The first is greater than the second.
42 > -48
f(g(3)) > g(f(3))
