The equation of a circle with a center of (h,k) with a radius of "r" is
looking at the given equation,
5x^2 +5y^2=20
divide 5 to both sides to get
x^2+y^2 =4
now compare that to the equatio of a circle shown above
The expression for volume is l•w•h (length times width times height). For example, you could say:
Amber is filling a cube with sand. She wants to find out the volume of the box to find out how much sand she needs. She knows that the length is 7 inches, the width is 3 inches, and the height is 4 inches. What is the volume of the cube?
Answer:
infinitely many
Step-by-step explanation:
You have the system
(1/2)x + 5y = 6
3x + 30y = 36
Multiplying the first equation by 6 results in 3x + 30y = 36, which is exactly the same as the second equation. The two graphs coincide, and so there are infinitely many solutions to this system
Hold on- I didn't read the question correctly! Just one moment.
