Answer:

yes

Step-by-step explanation:

Substitute x = 2 and y = 2 into both equations and if both are true then (2, 2) is a solution of the system.

y = x, that is

2 = 2 ← True

x + 2y = 6, that is

2 + 2(2) = 2 + 4 = 6 ← True

Thus (2, 2) is a solution of the system

Answer:

C

Step-by-step explanation:

So this is transformations

So this seems like it was rotated 180 degrees then dilated by a scale factor

The rule for 180 degrees is (-x,-y)

The rule for dilations is (2x,2y)

So the answer should be

C. (-2x,-2y)

A foam cylinder, with a diameter of 3 inches in height of 8 inches, is carved into the shape of a cone. What is the maximum volu
Delvig [45]

Answer:

volume of cone = 1/3 volume of cylinder

according to the question, volume of cylinder =

V =

\pi \times (r) {}^{2} h

diameter = 3 inches

radius = 3/2 inches

height = 8 inches

V = 22.7 * (3/2)²* 8

V = 22.7 * 9/4 * 8

V = 22.7 * 18

maximum volume a cone can have = 1/3 of cylinder

Volume of cone = 1/3 * 22.7 * 18

= 22.7 * 6

= 132.6
