First, you have to multiply 12×24.50=$360.00. Next, you have to subtract 372.75-360.00=12.75. Then, you have to divide 12.75÷5=$2.55. So in conclusion, each lightsaber costs $2.55.

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.

const2013 [10]

Answer:

y + 12 = 3(x - 2)

Step-by-step explanation:

Insert the coordinates into the formula with their CORRECT signs. Remember, in the Point-Slope Formula, y - y₁ = m(x - x₁), all the negative symbols give the OPPOSITE term of what they really are. Since both lines contain have to have similar rate of changes [slopes], we do not go any further.

How to condense logs using properties of logs

Mkey [24]

The logs rules work "backwards", so you can condense ("compress"?) strings of log expressions into one log with a complicated argument. When they tell you to "simplify" a log expression, this usually means they will have given you lots of log terms, each containing a simple argument, and they want you to combine everything into one log with a complicated argument. "Simplifying" in this context usually means the opposite of "expanding".

There is no standard definition, in this context, for "simplifying". You have to use your own good sense. If they give you a big complicated thing and ask you to "simplify", then they almost certainly mean "expand". If they give you a string of log terms and ask you to "simplify", then they almost certainly mean "condense".
