Determine is the solution set for the system of equations shown is the empty set contains one point or is infinite X+2y=0; 2x+4y
Sedaia [141]
We can use elimination to solve the system:

x+2y=0           Multiply the first equation by negative 2 so we can eliminate
2x+4y=0

-2-4y=0         Add them, -2X+2X= 0, -4Y+4Y= 0
2x+4y=0                   

0=0 

Since 0 is indeed equal to 0 you have INFINITELY MANY SOLUTIONS.

you could also put both equation in slope intercept form and see if the slopes and Y-intercept are the same.

A cone has a volume of 144 in3 and a diameter of 12 inches. Wilson states that a cylinder with the same height and diameter has
liraira [26]

Answer:

No

Step-by-step explanation:

Given:

Volume of cone = 144 in³

Diameter of 12 inch

Find:

Volume of cylinder[Same height and radius] is 144 in³ or not

Computation:

Volume of cone = [1/3][π][r²][h]

144 = [1/3][3.14][(12/2)²][h]

144 = 37.68 h

Height of cone = 3.82

Volume of cylinder[Same height and radius] = [π][r²][h]

Volume of cylinder[Same height and radius] = [3.14][6²][3.82]

Volume of cylinder[Same height and radius] = 431.81

Volume of cylinder[Same height and radius] = 432 in³

So,

Volume of cylinder[Same height and radius] is not 144 in³
