Given:
A graph that contains image and preimage.
To find:
Which figure is the preimage and which figure is the image.
Solution:
Initial figure is known as preimage and translated figure is known as image.
It is given that a triangle was translated 4 units down. It means, the upper triangle is preimage and the lower triangle is the image.
So, ΔFGH is the pre-image and ΔABC is the image.
Therefore, the correct option is B.
Answer:
7x²+ 25x
Step-by-step explanation:
Answer: 90 degress clockwise
Step-by-step explanation: because it is going the way the clock is going and it only went one time which is 90 degrees
Okay, so first lets think about the angle next to the 42 degree angle.
we know that those two angles must add to 180 degrees, so lets form an equation to figure out the other angle
42 + x = 180
subtract 42 from both sides
x = 138
so 138 degrees is the first AND the 3rd angle
the opposite angle from the 42 degree angle also happens to be 42 degrees
this is because there are two lines in total right?? if you draw out the 42 degree angle and the 138 degree angle, flip that upside down, the angles are the same!!
i hope this helps!!
The area of a triangle formula is b×h×1/2, so 12×5a+7b is 60a+84b.
Multiply that by a half.
60a+84b × 1/2
30a+42b
