HELP PLEASE THIS IS MY LAST ASSIGNMENT OF THE SEMESTER!! Solve the following system of equations with any method. Show all work and explain your thinking for each step in the process.
2x-10y=10
5x+9y=-9

(0,-1) x = 0, y = -1

Step-by-step explanation:

You can first re-arrange the items to y= (something) or x=(something) in the first equation. Then, lets say we use y=(something) and subsitute it for the why in the second equation. 5x+9(something)=-9.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
