Answer:
10/45 == 2/9
Step-by-step explanation:
We are given the two functions:
f(x) = 2x + 7
g(x) = 6x – 5
Part A. Find (f + g)(x)
(f + g)(x) = f(x) + g(x)
(f + g)(x) = 2 x + 7 + 6 x – 5
(f + g)(x) = 8 x + 2
Part B. Find (f ⋅ g)(x)
(f ⋅ g)(x) = f(x) ⋅ g(x)
(f ⋅ g)(x) = (2 x + 7) (6 x – 5)
(f ⋅ g)(x) = 12 x^2 – 10 x + 42 x – 35
(f ⋅ g)(x) = 12 x^2 + 32 x – 35
Part C. Find
f[g(x)]
f[g(x)] = 2 (6
x – 5) + 7
f[g(x)] = 12 x
– 10 + 7
f[g(x)] = 12 x

Answer:
<u>Janet's interest is $3.90 every month.</u>
Step-by-step explanation:
First, you need to set up a proportion to find Janet's interest:
0.65%/100 = x/600
Step 1: Cross-multiply.
0.65/100/100 = x/600
(0.65/100)*(600)=x*(100)
39/10=100x
Step 2: Flip the equation.
100x=39/10
Step 3: Divide both sides by 100.
100x/100=39/10/100
x=39/1000 (0.039)
Then move the decimal twice to the left to find the dollar amount:
0.039 ⇒ 3.90
Janet's interest is $3.90 every month.
