Answer:
The solution would be (6, -11)
Step-by-step explanation:
In order to solve this system by substitution, simply take the value of y in the first equation and use it in place of y in the second. This will allow you to solve for x.
x = -2y - 16
x = -2(-3x + 7) - 16
x = 6x - 14 - 16
x = 6x - 30
-5x = -30
x = 6
Now that we have the value of x, we can find the value of y.
y = -3x + 7
y = -3(6) + 7
y = -18 + 7
y = -11
Answer:
Here is the break down of the answer x=6 and y=-11
Step-by-step explanation:
B) yes, by SAS similarity criterion
C) yes, by SSA similarity criterion
D) no, not possible to tell.
Answer:
Option A is correct.
Yes, by AA similarity criterion
Step-by-step explanation:
AA(Angle-Angle) Similarity Criterion states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
In ΔBAC and ΔCED
[Angle] [Given]
[Angle] [Common angle]
Therefore, by AA similarity criterion;
Therefore, ΔBAC and ΔCED are similar by AA similarity criterion.
-2, 6, -18, 54,...
Answer:
the common ratio is -3

Step-by-step explanation:
To draw the plan of the class foundation using a scale of 5m to 4cm, you'll need to create a scaled-down representation of the room, including the door and windows. Here are the steps to draw the plan:
1. Determine the size of your drawing area. Since the scale is 5m to 4cm, you need to calculate the dimensions of your drawing area.
Length of the class: 20m
Breadth of the class: 10m
Using the scale, for every 5 meters in reality, you will represent it as 4 centimeters in your drawing. So, you'll need a drawing area that can accommodate these dimensions, and the scale conversion.
Length of drawing area = (20m / 5m) * 4cm = 16cm
Breadth of drawing area = (10m / 5m) * 4cm = 8cm
Therefore, your drawing area should be approximately 16cm by 8cm.
2. Draw the outline of the class: Using a ruler and a pencil, draw a rectangle with dimensions 16cm by 8cm to represent the classroom. This rectangle represents the foundation of the class.
3. Draw the door: The door is 8 meters long and 4 meters wide. Using your scale, you'll represent it as 4cm by 2cm in your drawing. Draw a rectangle within the classroom rectangle to represent the door. The top edge of the door should align with one of the longer sides of the classroom.
4. Draw the windows: The windows are 5 meters long and 3 meters wide. Using your scale, you'll represent each window as 4cm by 2.4cm in your drawing. Place the windows where they would be on the classroom walls, leaving space between them and the door.
5. Label the drawing: You can label the door and windows to indicate their dimensions if needed.
