Hello! The graph of each linear equation is a set of unconnected points. The thing is that with a solid line, you can have things in-between whole numbers. However, you can’t have a fraction of a movie. Dotted points show that you can’t have in between values and that only whole quantities count.
Answer:
a
Step-by-step explanation:
Hello,
Let's be x and y the 2 numbers
x+y=20==>y=20-x
P(x)=x*y=x*(20-x)=20x-x²
Max(P(x))==>P'(x)=0= 20-2x==>2x=20==>x=10
A product is maximum is the 2 numbers are equals;
Numbers are 10 and 10 and product=100

Answer:
x= 0.9
step-by-step explanation:
LCM=3x
use the lcm to multiply each term
3x×1/3+3x×3=3x×3/x
cancel out
x+9x=9
10x=0
divide both side by the coefficient of x
10x/10=9/10
x=0.9
