Answer: A

Step-by-step explanation:

You can solve a system of equations by graphing, elimination, substitution, or using a combination. The graph of a linear equation is a line. The point(s) where one line intersects another is the solution to the system. Therefore, since Lucy found that the lines intersected at the point (-4, 1), it is the solution to the system of linear equations

The sum of the interior angles of a polygon with $n$ sides is

$180(n-2)$

Since a pentagon has 5 sides, the sum of its interior angles is

$180(5-2) = 180 \cdot 3 = 540$

Since it is a regular pentagon, all sides and angles are the same, so one single angle measures

$\dfrac{540}{5} = 108$ degrees.

Li made a scale drawing of a room. The scale used was 5cm=1m.The scale drawing is the preimage and the room is the dilated image

AleksandrR [38]

Scale in terms of cm to m= 1/5
In every meter there are 5 cm

Considering this, if the dimensions are 15cm and 20cm, you would need to multiply them by 5 to convert them to meters

15*5= 75 20* 5=100

Dimensions- 75ft by 100ft
