What makes a box-and-whisker plot unique?
ESSENTIAL QUESTION
Solve for x.

3x + 2y = 25
4x + 5y = 38
In the 1600s, a blacksmith could make a living by hand-forging horseshoes and nails. A diligent blacksmith could make one horseshoe in 12 minutes and a nail in 1 minute. In the 1600s, it would take the blacksmith 210 minutes to complete a particular job. With advances in technology, the blacksmith was able to make a horseshoe in 9 minutes and a nail in 40 seconds, and could complete the same job in 155 minutes.

In the equations below, h represents the number of horseshoes in the job, and n represents the number of nails in the job.

12h + n = 210

9h + n = 155

How many nails were in the job the blacksmith completed?

An object is launched from the ground upward with an initial velocity of 35 meters per second. The object’s distance, d, above the ground at any time, t, can be represented by the equation below.
After how many seconds will the object hit the ground?

d = 35t - 5t
