Answer:
Square
Step-by-step explanation:
Plot the vertices of the quadrilateral PQRS on the coordinate plane (see attached diagram). The diagram shows that this is a square. Let's prove it.
1. Find all sides lengths:

All sides have the same lengths.
2. Find the slopes of all lines:

Since the slopes of PQ and RS are the same, lines PQ and RS are parallel. Since the slopes of QR and SP are the same, lines QR and SP are parallel.
The slopes
and
have the product of

then lines are pairwise perpendicular.
This means PQRS is a square.
Answer:
$ 2100
Step-by-step explanation:
De la pregunta anterior:
1 metro de cerca de alambre = $ 150
14 metros = x
Cruz multiplicar
x = 14 × $ 150
x = $ 2100
Por lo tanto, costaría $ 2100 por una cerca de 14 metros
Answer:
B y=8x
Step-by-step explanation:
A proportional relationship must go through the point x=0, y=0 and be in the form y=kx where x is a constant
A) y = x^8
B) y = 8 x
C) y = x^8 + 8
D) y = 8 x + 8
The only points that is in the form y= kx is option B
C and D do not go through x=0, y=0 and A is not in the form y=kx where k is a constant
Answer:
90 miles
Step-by-step explanation:
1 1/2 is half of 3 so just multiply 45 by two
Answer:
A. (9,-5)
Step-by-step explanation:
Translation down is -2 to the y coordinate, which is (5,-5). Then you translate it right 4 units, which is +4 to the x coordinate, so the final coordinate is (9,-5).
