Which of the following ordered pairs represents the solution to the system given below?
castortr0y [4]
X − 4y = 7
5x + 9y = 6

5x − 20y = 35  //1st * 5
5x + 9y = 6

5x +9y - 5x + 20y = 6 - 35  //2nd - 1st
5x + 9y = 6

29y=-29
5x=6-9y

y=-1  //1st : 29
5x=6-9*(-1)

y=-1
x=15:5 //2nd : 5

y=-1
x=3

check:
for x=3 and y=-1 there is:
x − 4y = 7 is 3 − 4*(-1) = 7 is 7=7 ok
5x + 9y = 6 is 15-9=6 is 6=6 ok

answer: (3;-1) represents the solution.

The height of a cone is equal to the diameter of the base. What expression represents the volume of the cone, in cubic units?
Maurinko [17]
By definition, the volume of a cone is given by:
 V = (1/3) * (\pi) * (r ^ 2) * (h)

 Where,
 r: radius of the circular base
 h: height of the cone
 Let's define a variable:
 x: diameter of the base
 We have then that the radio is:
 r = x / 2

 The height is:
 h = x

 Substituting values:
 V = (1/3) * (\pi) * ((x / 2) ^ 2) * (x)

 Rewriting:
 V = (1/3) * (\pi) * (x ^ 2/4) * (x)

V = (1/12) * (\pi) * (x ^ 3)
 Answer:
 
An expression that represents the volume of the cone, in cubic units is:
 
V = (1/12) * (\pi) * (x ^ 3)
