Answer: 5.25y
Step-by-step explanation:
To Multiply 18y by 7/24,
we first convert the fraction to decimal.
7/24 = 0.2916667
Then, multiply by 18y
18y x 0.2916667
= 5.25y
The given line (in blue) is a vertical line, so it is in the form
Ax=C (i.e. with the y-term missing).
Since we know that the line passes through (-2,2), and (-2,-3), this means that all points on the line has the x-coordinate equal to -2 (characteristic of vertical lines).
The equation is therefore
x=-2, or alternatively
x+2=0

Answer:
20 miles
Step-by-step explanation:
The north and east distances form the legs of a right triangle. The straight-line distance between the trains is the hypotenuse of that triangle. The Pythagorean theorem can be used to find the length of the hypotenuse (d).
d² = 12² +16²
d² = 144 +256 = 400
d = √400 = 20
The two trains are 20 miles apart.

<em>Additional comment</em>
You may recognize the given distances are in the ratio 3 : 4. You may recall that side ratios of 3 : 4 : 5 make a right triangle. If so, you recognize that the straight-line distance is (4 miles)×5 = 20 miles. (3:4:5 right triangles show up often in algebra and geometry problems, so might be something you want to look for.)
