Answer:
$4.5
Step-by-step explanation:
Hot dogs=h
Cheese burgers=c
2h+3c=20
2h+5c=29
There are two ways to solve-
1. Elimination- multiply the bottom by -1.
2h+3c=20
-2h-5c=-29
-2c=-9
c=4.5
2. Just move 2h, and you get 2c=9, 4.5
There are g(f(x)) and f(g(x))
do them then evaluate
lets say
f(x)=3x
g(x)=9x^3-4
g(f(x))=9(3x)^3-4=243x^3-4
f(g(x))=3(9x^3-4)=27x^3-12
we can see that g(f(x)) with yield a higher value for x=10
Answer:
last option
Step-by-step explanation:
Sin A: opp/hyp (opposite/hypotenuse)
opposite of A is 24 and the hypotenuse is 30
write that as a fraction: 24/30
simplify and it is: 4/5
Cos A: adj/hyp (adjacent/hypotenuse)
adjacent side of A is 18 and the hypotenuse if 30
write that as a fraction: 18/30
simplify and it is: 3/5
