Answer: negative
Step-by-step explanation:
With yx = zx, then by the Multiplicative Property of Equality, y = z. Since z is a negative integer, then y is also a negative integer. Since yx is positive, with y equal to a negative integer, then x is negative.
The term "autonomous" refers to an ordinary differential equation that relates the derivatives of the dependent variable as a function *only* of the dependent variable. In other words, the ODE doesn't explicitly depend on the independent variable.
Examples:

is autonomous

is *not* autonomous
Yes because you only need to look at the first decimal for problems like these and the first number you see a seven and a one and seven is greater than one
15+(10-x)=15 would be your equation if that is what you are looking for.
Part A:
3.14 X (4)^2 X 3/3
= 50.26548246
