Parallelogram FGHI on the coordinate plane below represents the drawing of a horse trail through a local park: In order to build

a scale model of the trail, the drawing is enlarged as parallelogram ABCD on the coordinate plane. If two corners of the trail are at point A (0, 4) and point D (−6, −5), what is another point that could represent point C?
A-(9,-5)
B-(6,-5)
C-(12,-5)
D-(3,-5)

Let's check the scaling of the direction vectors, the difference between the points. We'll assume FI is mapped to AD.

F - I=(-6 - -8, 6 - 3) = (2,3)

A - D = (0 - - 6, 4 - -5) = (6,9)

We see A-D=3(F-I); that is, we're dealing with a scale factor of 3.

FG is 4 units long so AB will be 4(3)=12 units long.

All the choices have positive x so we don't have to worry about the possibiity that the big parallelogram is all to the left of the y axis.

B=A+(12,0)=(12,4)

C=D+(12,0)=(6,-5)

Reviewing the choices we get

Answer: B

I need answers for them three
sergeinik [125]
These are the answers. You subtract 6 from -3 giving you n≥-9. Since n/3 is a fraction, in order to undo it we must multiply it to the other side, giving us n≤-63.

1. n≥-9
3. n≤-63

I hope it helped!

Answer:

(2,21)

Step-by-step explanation:

y = 10.5x

plug 2 for x  in the equation

y = 10.5(2)

then multiply 2 by 10.5

y=21

4x + 1/3 y 2 what is the value of the expression above when x = 2 and y = 3
GenaCL600 [577]
Hoi!

To solve this, first plug in the values for x and y.

x = 2, so anywhere you see x, put 2 in its place.

y = 3, so anywhere you see y, put 3 in its place.

4(2) +  \frac{1}{2}(3)

4 × 2 = 8

\frac{1}{2} × 3 = 1 \frac{1}{2}


8 +1 \frac{1}{2} = 9 \frac{1}{2}

9 \frac{1}{2} is your answer.
