20+6=6+20
20
That's an equation where x = 5
No, it is an equation. n+6 is an expression.
It is a linear equation in the variable r.
== == y = -x + 5
20+6=6+20
20
That's an equation where x = 5
It is an equation and the value of n is 20
No, it is an equation. n+6 is an expression.
It is a linear equation in the variable r.
It is an equation and the value of x is 8
x = 3.75
Rewrite the equation as y = -(3/4)x - 5 The slope = coefficient of x = -(3/4) = -0.75
20 = 400
Better formatting is cos(2x+20)=-0.5
