Answer:
So, the initial number of apples is 7.
Step-by-step explanation:
The number of apples of An, Binh, and Chi are the same. An gave away 17 apples, Chi gave away 19 apples, so now Chi's apples are 5 times higher than the total remaining apples of An and Binh. How many apples did each of you have at first? (Solve the above problem by equation or system of equations)
Let the initial numbers of apples is a.
An gave 17 apples
Chi gave 19 apples
So,
x - 19 = 5 (x - 17 + x)
x - 19 = 5 (2x - 17)
x - 19 = 10 x - 85
9 x = 66
x = 7
Answer:
Given the statement: if y =3x+6.
Find the minimum value of 
Let f(x) = 
Substitute the value of y ;

Distribute the terms;

The derivative value of f(x) with respect to x.

Using 
we have;

Set 
then;


By zero product property;
and 2x + 3 = 0
⇒ x=0 and x = 
then;
at x = 0
f(0) = 0
and
x = -1.5

Hence the minimum value of
is, -5.0625
Step-by-step explanation:
a)82km into miles
Sol'n
Here,
km=82=82000miles
m=?
Now,
Miles =km×1000
=82×1000
=82000
Therefore,82000m.
