Answer:
Y= -4x+ 21
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
it's an acute angle so it has to less than 90 and 71 just seems like it's too much
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
The Answer Is 18
Order Of Operation laws says that you must do the parentheses first, 45x2.
45x2=90
The next thing you must do is divide 90 by 10 since division is before addition.
90/10=9
Now combine like terms.
9+9=18
2^-2 would become 1/2^2 which becomes 1/4.
