When raymond observes certain natural phenomena, he often forms ideas about their causes and effects. suppose that raymond
surmises that leaves change color in autumn due to scarcity of sunlight. in order to test whether his idea is accurate, he must first
construct a falsifiable “answer”
that defines a clear relationship between two variables. raymond's next step is to “answer”
that would isolate and test the relationship between the two variables. this task can be pretty
daunting because raymond will need to identify and eliminate any “answer”
variables that could confuse test results.
1st theory, law, hypothesis
2nd design an experiment , complete mathematical calculations, propose an explanation
3rd confounding, dependent, independent.

no this is a nonlinear negative

answer: when you burn wood, the carbon reacts with the oxygen in the air to create ash and smoke. that is a permanent change you cannot undo that.

step-by-step explanation:

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.

it would have to be 3/0
