Answer:
The number is 35
Step-by-step explanation:
Let x be the number
1/5 x + 3x
=
2x + 42 Break the question into phrases and solve 1 phrase at a time.
1/5 = 0.2
0.2x + 3x = 2x + 42 Combine the left
3.2x = 2x + 42 Subtract 2x from both sides
3.2x - 2x = 42 Combine
1.2x = 42 Divide by 1.2
x = 42/1.2
x = 35
The answer to the problem is 12-6x
Range: (-infinity, 4]

minimum: (-infinity, infinity)
keep it in same format as you have for the maximum
increasing
the interval -infinity
