Answer:
The least common multiple of 30, 25, 4 is 150.
Step-by-step explanation:
The given numbers are 30, 25 and 4.
The factors of given numbers are



The L.C.M of given numbers is a smallest number that divides the given numbers completely.


Therefore the least common multiple of 30, 25, 4 is 150.
The value of the rate of change of the function is 14a + 7h
<h3>Rate of change of function</h3>
The rate of change of function is also known as the slope expressed according to the equation shown below;
f'(x) = f(a+h)-f(a)/h
Given the function below expressed as:
f(x) =1 + 7x^2
<u>Determine the function f(a)</u>
To determine the function, simply replace x with 'a" to have:
f(a) =1 + 7a^2
Determine the function f(a+h)
f(a+h) = 1 + 7(a+h)^2
f(a + h) = 1 + 7(a^2+2ah+h^2)
f(a + h) = 1 + 7a^2 + 14ah + 7h^2
To determine the rate of change
f'(x) = f(a+h)-f(a)/h
f'(x) = 1 + 7a^2 + 14ah + 7h^2 - 1 - 7a^2/h
f'(x) = + 14ah + 7h^2/h
f'(x) = 14a + 7h
Hence the value of the rate of change of the function is 14a + 7h

Answer:
A
Step-by-step explanation:
8x (the babysitter gets paid 8 dollars an hour, and x represents number of hours)
3 (this is the additional tip the babysitter gets; it's not dependent on the number of hours she/he works)
The babysitter will get paid the same despite babysitting two kids- no variable here is dependent on the amount of kids the babysitter babysits.
Answer:
6
Step-by-step explanation:
The main idea of how to solve it is to isolate the variable. Whatever you multiply, divide, add, or subtract on one side, you must do the same to the other side so that both sides are equal.
3(x-1) = 21
3(x-1) / 3 = 21 / 3
x - 1 = 7
+ 1 + 1
x = 6
