Answer:
x ≥ 1
Step-by-step explanation:
There are no domain restrictions on a(x), so we can find the domain of the composite function by looking at that composition:
The argument of the square root function must be non-negative, so we must have ...
3(x -1) ≥ 0
x -1 ≥ 0 . . . . . divide by 3
x ≥ 1 . . . . . . . add 1
The domain of b(a(x)) is x ≥ 1.
The perimeter is 24 but I’m not sure about the area
Expanded form is when you take a number, and add its digits together, reforming the number. For example, 1,523 would be 1,000 + 500 + 20 + 3
Here are a few examples:
2,000 + 400 + 50 + 7 = 2,457
200,000 + 700 + 10 + 2 = 200,712
50,000 + 800 + 50 + 6 = 50,856
60,000,000 + 200,000 + 50,000 + 1,000 + 400 + 20 + 3 = 60,251,423
So, 20,484,163 is equal to
20,000,000 + 400,000 + 80,000 + 4,000 + 100 + 60 + 3 = 20,484,163
I hope I helped!

Answer:
A. y = -3/2x + 1
B. y = -5/3x + 10
C. y = -x + 6/5
Step-by-step explanation:
A. You just have to isolate the y so divide by 4: y = -3/2x + 1
B. 3y = -5x + 30
Divide by 3: y = -5/3x + 10
C. -5x + 6 = 5y
Divide by 5: -1x + 6/5 = y OR y = -x + 6/5
