Answer:
875
Step-by-step explanation:
As given, there is a three digit number
So, let assume three digit number be `xyz`.
Now, as given tens digit is 2 greater than the unit digit.
∴
Next, the hundred digit one greater than the tens digit.
∴
The sum of the tens and the hundreds digits is three times the units digit.
∴
Now, substituting the value in the equation.
⇒
solving it to get value of y
⇒
⇒
∴
Next, finding value of z
y=
substituting the value of y and subtracting both side by 2
∴ z=
Last, finding the value of x
substituting the value of y
∴ x= 8
xyz= 875
Answer:
C. A'(3,4), B'(-1,3), C'(-1,-1)
Step by step answer:
The coordinates of the vertices are A(-3,-4), B (1,-3), C(1,1).
We have the formula for the rotating a shape at an angle of 180° which shows that you are reflecting the shape twice.
(x, y) -> (-x, -y)
So, the coordinates will be,
A(-3,-4) = A'(3,4)
B (1,-3) = B'(-1,3)
C(1,1) = C'(-1,-1)
Thank you.
