A dealership recently sold a four-door sedan it purchased for $19,000 at 15% markup. It accepted a
trade-in for it, and it paid $5000 for the trade. The next
day, it marked it up 25% and sold it in a week. What was
the dealership's profit on these two vehicles?

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

this equation is in point-slope form.

where,

using this equation you can gather a point and the slope, which gives you enough information to draw a line. transform the equation to standard form to start.

the equation is now in standard form, we have a point, as well as the slope:

point: (0, -6)

slope: -2

plot (0,-6), then simply rise/run with the provided slope of -2, once you feel you have a comfortable amount of points - draw a line.
