4x+5y=17 4x+6y=-6 solve using eliminationshow work

-4x+4x +5y +6y = 17-6

11y=11

divide both side by 11 to isolate y

y=1

4x+6(1) = -6

subtract 6 on both sides

4x=-12

divide 4 on both sides

x=-3

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 !

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
