A) (-2, 5)
B) (1, 4)
C) (2, -1)
D) (4, -4)
Answer:
(C) (2,-1)
Step-by-step explanation:
The given system of equations is :
(1)
and (2)
Multiply equation (1) with 2 and then subtract equation (2) from it, we get
⇒
⇒
⇒
Substitute the value of x=2 in equation (1), we get
⇒
⇒
⇒
Therefore, x=2 and y=-1. that is (2,-1).
Answer:
V =12.167 cm^3
Step-by-step explanation:
V = s^3 is the volume of a cube where s is the side length
The side length of the cube is 2.3 cm
V = ( 2.3 cm) ^3
V =12.167 cm^3
Hey there!
The FORMULA:
V = s^3
Your EQUATION:
v = 2.3^3
SOLVING for the EQUATION
v = 2.3^3
2.3^3 = v
(2.3 cm)^3
≈ 2.3 cm * 2.3 cm * 2.3 cm
≈ 5.29 cm * 2.3 cm
≈ 12.167 cm^3
v ≈ 12.167 cm^3
Therefore, your answer is: 12.167 cm^3
Good luck on your assignment and enjoy your day!
