Answer:
Brainliest!!!
Step-by-step explanation:
options:
A. A translation of 3 units to the left followed by a reflection across the x-axis
B. A rotation of 90 clockwise followed by a translation of 6 units to the left
C. A translation of 5 units to the left followed by a dilation of a factor of 2
D. A reflection across the y-axis followed by a rotation of 180 counterclockwise
All the other options deal with transformatios that just move the figure without modifying their dimmenssions.
When you dilate a figure you increase the dimmenssions, so the result is a different figure.
the answer is C
180
Explanation:
Set a equation of a ratio 120/90=x/135
And calculate!
90x=(120)(135)
90x=16200
x=180
Answer:
The solution of the system of equations is the point 
Step-by-step explanation:
we have
-----> equation A
-----> equation B
Multiply the equation B by 2 both sides
------> equation C
Adds equation A and equation C
Find the value of y
Substitute the value of x in equation A
The solution of the system of equations is the point
Let's rewrite the expression as
So, if 
, you may divide both sides by 
, the equation becomes 
, and the only solution is 
, which means that this is not an identity (an indentity is tautologically true, no matter the value of x).
If instead 
, you are multiplying both sides by zero, so the equation becomes
So, it doesn't matter which value for x you choose, because you will always end up with 
, which is obviously always true.
