Answer:
f(x) = 25.50x Roberto can buy 7 video games
Step-by-step explanation:
Each game is $25.50 which in math means it has an "x"
So if x=1 then 25.50x says that 1 video game is $25.50
Set up the equation:
200 = 25.50x (divide both sides by 25.50 to isolate the x)
200/25.50 = 7.84
x = 7.84
You can't have 0.84 of a video game, so Roberto can only buy 7 of them.
Answer:
Option B is correct
Step-by-step explanation:
We need to find g(h(f(x))
We first find h(f(x))
f(x) = x-3/x
Putting value of f(x) in place of x in h(x)
h(x) = 2x+1
h(f(x)) = 2(x-3/x) + 1
= 2(x-3/x) + 1
= 2x -6 /x +1
= 2x-6 +x/x
= 3x-6/x
Now, putting value of h(f(x)) in g(x)
g(x) = x+3
g(h(f(x)))= (3x-6/x) + 3
= 3x-6/x + 3
= 3x-6+3x/x
= 6x-6/x
So, Option B is correct.
Not an answer, but we need the info on the table...
Answer:
No solution
Step-by-step explanation:
8+8-4 = 12
12+ n = 3n-2n
3n-2n
12+n3n-2n
subtract n on both sides
12=0n
This makes it no solution
Answer:
3 raise to -7 ÷3 raise to -10 × 3 raise to -5
3 raise to -7-(-10)×3 raise to -5
3 raise to 3×3 raise to -5
3 raise to 3+-5
3 raise to -2
