Answer:
The boy's feet are closer to the surface of the pool because negative 4 over 5 < negative 2 over 5.
Step-by-step explanation:
3x+7y-12=0
3x+7y=12
3x=12-7y
x=12-7y/3
All of those are true, except the one about the radius. Because alternate definition of diameter uses the idea of chord. So, both ends of a chord have to be on the circle, but one end of a radius is at the center, so a radius can't be a chord.
Answer: 35 and 27
Step-by-step explanation:
We can solve this by using a system of equations
x will be the first number while y will be the second

This equation means the two numbers will add to get 62

This equation means when subtracted the two numbers will have the difference of 8.
Now I will solve by elimination

When adding the two equations why was eliminated so now we can find the value of x

Now sub in x into one of the original equations to find the value of y

Answer:
-1
Step-by-step explanation:
-1^2 = -1
