Answer:
Step-by-step explanation:
As written, they all are linear functions.
If we assume that x3 is supposed to be interpreted as x³ = x^3, and that x2 is supposed to be x² = x^2, then the equations containing those terms are not linear equations.
The equation y = 1/5x is usually interpreted to mean y = (1/5)x. If it is intended to be y = 1/(5x), then it is not a linear function either.
___
A linear function is a sum of terms that are either constant or containing a single variable to the first power.
Answer:
x = 37
Step-by-step explanation:
3y - 20 + x + 13 = 3x + 9
3y - 16 = 2x
1.5y - 8 = x
2y + 3x + 9 = 180
2y + 3x = 171
2y + 3(1.5y - 8) = 171
2y + 4.5y - 24 = 171
6.5y = 195
y = 30
1.5y - 8 = x
1.5 * 30 - 8 = x
45 - 8 = x
37 = x
