40 people
wheat flour per person-2 kg
corn flour per person-3 kg
rice per person-4 kg
Number of proper subsets = 2^number of elements- 1
= 2^n - 1
No of elements = 4
2^4-1 = 16-1 = 15
To graph the equation of the line, find the x-intercept and the y-intercept of the function
we have

we know that
The x-intercept is the value of x when the value of y is equal to zero
The y-intercept is the value of y when the value of x is equal to zero
Step 1
<u>Find the x-intercept</u>
For 



the x-intercept is the point 
Step 2
<u>Find the y-intercept</u>
For


the y-intercept is the point 
Step 3
Graph the points and draw the line
see the attached figure
therefore
the answer in the attached figure
Answer:
10
Step-by-step explanation:
used Pythagorean theorem
a ^2+b^2=c^2
6^2+8^2=c^2
36+64=c^2
c^2= 100
find square root of 100 to find c
=10
The answer is D because you would do factor by grouping
