The derivative of a variable raised to exponent of n, x^n is equal to the product of n and x raised to exponent of n-1.
d(x^n) = (n)(x^n-1)
So, from the given
d(9x + 5) = (1)(9x^1-0) + 5(0)
= 9
The given value of x is irrelevant to this item because the derivative does not contain any variable x.
Answer:
Option (C) Miguel's daily wage=$70
Step-by-step explanation:
This can be expressed as;
Total amount a week=Amount he earns per day×number of days he works in a week
where;
Total amount a week=$490
Amount her earns per day=x
Number of days in a week=7 days, since wages are paid weekly even on days that Miguel does not go to work, like weekends.
replacing;
490=x×7
x=490/7
x=70
Miguel's daily wage=$70
Answer:
x=4
Step-by-step explanation:
1. isolate the variable by subtracting 7 on both sides: 4x=23-7
2. simplify: 4x=16
3. divide both sides by 4: x=16/4
4. simplify: x=4
Compare two similar sides:
24:32 this reduces to 3:4
Answer: D) 3:4
