Answer:
The system of equations representing the situation are
600a + 1200p = 15,000
a + p = 16
with solutions
p = 9
a = 7
Step-by-step explanation:
No he would be incorrect because if you add 6 and 8 you get 14 and 14 is an even number. I hope this helps!
Answer:
12
Step-by-step explanation:
(5×6)-½(3×6 + 2×4 + 2×5)
=30 - ½(18+8+10)
= 30 - ½(36)
=30-18= 12
Given:
Nana has a water purifier that filters
of the contaminants each hour.
Water has contaminants = 
To find:
The function that gives the remaining amount of contaminants in kilograms, C(t), t hours after Nana started purifying the water.
Solution:
Let C(t) be the remaining amount of contaminants in kilograms after t hours.
Initial amount of contaminants = 
Decreasing rate is
.
Using the exponential decay model:

where,
is initial amount of contaminants, r is the decreasing rate and t is time in hours.
Substituting the values, we get


Therefore, the required function is
.
Here u can see rate of cahnge of y over x is called slope =5
So point slope form of a line
Y-y1=m(x-x1)
Y-15=5(x-3)
