Answer:

112\pi ~ units^{3}

Step-by-step explanation:

Radius(r)=4 ~units

Height(h)=7~units

So,~ the ~volume ~ of ~ the ~ cylinder

=\pi r^{2} h

=\pi (4)^2(7) units^3

=\pi (16)(7) units

= 112\pi~ units^3

How many solutions does the following system have? <br><br> 2x+3y=1; -3x-2y=-1
zysi [14]

Answer:

x = 1/5 , y = 1/5

Step-by-step explanation:

Solve the following system:

{2 x + 3 y = 1 | (equation 1)

-3 x - 2 y = -1 | (equation 2)

Swap equation 1 with equation 2:

{-(3 x) - 2 y = -1 | (equation 1)

2 x + 3 y = 1 | (equation 2)

Add 2/3 × (equation 1) to equation 2:

{-(3 x) - 2 y = -1 | (equation 1)

0 x+(5 y)/3 = 1/3 | (equation 2)

Multiply equation 1 by -1:

{3 x + 2 y = 1 | (equation 1)

0 x+(5 y)/3 = 1/3 | (equation 2)

Multiply equation 2 by 3:

{3 x + 2 y = 1 | (equation 1)

0 x+5 y = 1 | (equation 2)

Divide equation 2 by 5:

{3 x + 2 y = 1 | (equation 1)

0 x+y = 1/5 | (equation 2)

Subtract 2 × (equation 2) from equation 1:

{3 x+0 y = 3/5 | (equation 1)

0 x+y = 1/5 | (equation 2)

Divide equation 1 by 3:

{x+0 y = 1/5 | (equation 1)

0 x+y = 1/5 | (equation 2)

Collect results:

Answer: {x = 1/5 , y = 1/5
