By counting grid squares, we see the library is 5 miles north and 6 miles east of Ashley's house. Using the Pythagorean theorem, we can find the straight-line distance to be
.. d = √(5^2 +6^2)
.. = √(25 +36)
.. = √61 . . . . . miles
.. ≈ 7.81 . . . . miles

Line L passes through point (2, -5) and is perpendicular to the line with equation y = 7. Determine the equation of line L.
Wittaler [7]
<h3>Answer:</h3>

A) x = 2

<h3>Explanation:</h3>

<em>Try the answers</em>

Of the offered choices, the only ones that go through the given point are ...

... x = 2

... y = -5

The latter is horizontal and parallel to y = 7, so is not the choice you want. The appropriate choice is ...

... A) x = 2

_____

<em>Figure out the answer</em>

The given line is horizontal, so the line you want is vertical—of the form ...

... x = constant

The constant must be chosen so the line will go through a point with x=2. It should be obvious that the constant must be 2.

... x = 2 is perpendicular to y = 7 and goes through (2, -5).

kolezko [41]

Answer:

1. Alissa can conclude that there are fewer students at her school that want to visit Japan (7) than Australia (13)

I'm not sure about the 2nd question so you can use it if you want or just wait if someone else gives a different answer

2.

25 × 0.52 = 13 pets that don't have a home

25 - 13 = 12 pets that have a home

Pets that don't have a home is more than the pets that have a home

The statement is not misleading

Barack walks 2 kilometers south and then x kilometers east. ​ ​He ends 5 kilometers away from his starting position. ​ ​ Find x
amid [387]

Answer:

4.6 km

Step-by-step explanation:

-This is a Pythagorean Theorem problem where the distances walked are effectively the base and height of the imaginary right triangle thereof.

#Apply Pythagorean theorem to solve:

b^2+h^2=H^2\\\\2^2+x^2=5^2\\\\x^2=5^2-2^2=21\\\\x=\sqrt{21}\\\\x=4.58\  km

\approx 4.6\ km

Hence, the distance x is 4.6 km
