Step-by-step explanation:
Just substitute any number for one variable to find the value of the other.
Eg:
2x-y=11
2(1)-y=11
2-y=11
-2 -2
-y=9
-y/-1=9/-1
y=-9
So (1,-9) is a solution to the equation.
Follow the steps and find many more solutions.

Yesterday, 1/4 of 80 =20 gave their speeches, so there are 80-20=60 students left.
Today, 2/5 of 60=24 students gave their speeches, so there are 60-24=36 students who still haven't give their speeches
another way to think of it is 80*(1- 1/4)*(1- 2/5)=80*(3/4)*(3/5)=36
Answer:
All real numbers greater than or equal to 0.
Step-by-step explanation:
x must be greater or equal to zero because there is no real square root of a negative number.
So the lowest value of the function is 0 and it can be any value greater than that.
The answer is A because if you do 10*10*10 that would give you 1k and if u multiply that by 2 you get 2k
