Answer:
C. y = 20
Step-by-step explanation:
Given system of equations:
Multiply the second equation by 3:
Subtract this from the first equation to eliminate 3y:
Solve the resulting equation for x:
Substitute the found value of x into the original second equation and solve for y:
Answer: The radian is defined as the angle of a circle subtended by an arc equal in length to the radius. That definition is far less arbitrary than the definition of a degree so you could claim it is a better unit purely because of how it is defined.
Step-by-step explanation:
16 because 3 divided by 8 is 0.375 and 6 divided by 0.375 is 16.
Answer:
x = - 3
Step-by-step explanation:
g(x) = 4x + 1...... (1)
g(x) = -11.... (2)
From equations (1) & (2)
-11 = 4x + 1
-11 - 1 = 4x
-12 = 4x
-12/4 = x
-3 = x
x = - 3
