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
The point that the graphs of f and g have in common are (1,0)
<h3>How to get the points?</h3>
The given functions are:
f(x) = log₂x
and
g(x) = log₁₀x
We know that logarithm of 1 is always zero.
This means that irrespective of the base, the y-values of both functions will be equal to 0 at x=1
Therefore the point the graphs of f and g have in common is (1,0).

5y+2x-3=0
5y=-2x+3
y=-2/5 x+3
Sope intercept of the line is y=-2/5 x+ 3/5.
The intercept is 3/5.
Check: x=0 when y=3/5
5y+2x-3=0
5(3/5)+2x-3
3+2x-3=0
2x=0
x=0
Correct
The answer is 3/5.
18·8.7= 156.6
23·56.1= 1290.3
47·5.92=278.24
