Answer:
Step-by-step explanation:
a) fg(x)
--> f(5x)
--> 3(5x)+3
--> 15x+3
b) f+g(x)
--> 3x+3+ 5x
c) (f-g)(2)
3x+3- 5x
--> 3(2)+3-5(2)
--> -1
Answer:
y=2
x=3
Step-by-step explanation:
I'm not sure, but considering that 3/2 = 1.5 I'm assuming that the rest is proportional as well. Therefore, making x=3 and y=2 (4/2=2 and 6/2=3)
it is an irrational not sure but i don't believe that it could be put in an ratio, so I say an irrational number
42 in a 4x to 3x ratio
4x + 3x = 42
7x = 42
x = 6
43 can be put in a 4(6) to 3(6) ratio
which is a 24 to 18 ratio, also written as 24:18
Note:
<span>a(b) = ab = a x b = a times b</span>
