Answer:
10x-48y
Step-by-step explanation:
Answer:
n= 98/3
Step-by-step explanation:
1. Complete distributive property *5(n-14)* and *2(n+14)*
5n-70=2n+28
2. Subtract 5n from both sides
-70=-3n+28
3. Subtract -70 from both sides
-98=-3n
4. Divide the variable from both sides *-3n*
-98/-3
5. Simplify
98/3
Final Answer:
98/3
Answer:
average rate of change = 30
Step-by-step explanation:
the average rate of change of f
(
x)
over an
interval between 2 points is the slope of the secant
line connecting the 2 points
It is calculated as

Answer:
Step-by-step explanation:
-Let t denote time and h(t) be the function that denotes the temperature after time t
-Also, let's take x°F to be the initial temperature of the vinegar.
Since, the temperature increases by 2.3°F every 5 minutes, we determine the rate of change per minute:
The situation can thus be expressed as:
It’s a because you have to calculate and do the formal slope
