Solve the system of equations algebraically. Verify your answer using the graph.

For this case we have the following system of equations:

$y = 4x-5\\y = -3$

We solve by the matching method.

Matching we have:

$-3 = 4x-5\\-3 + 5 = 4x\\2 = 4x\\\frac {2} {4} = x\\x = \frac {1} {2}$

Thus, the solution of the system is given by:

$(x, y): (\frac {1} {2}, - 3)$

Answer:

$(x, y): (\frac {1} {2}, - 3)$

15 cm<br> 4 cm<br> cm<br> V=____cm3

bonufazy [111]

Answer:

V=(πr^2 x h)/3

lets use π as 3.14 cause I dont know what pi u using

3.14 x 4^2 x 15 = 753.6/3 = 251.2

If you're using π as your pi, than just replace 3.14 by π on calculator

Hope that answers your question
