90 - x = 4x
4x + x = 90
5x = 90
x = 90/5
x = 18
Answer: x ~34.31 (rounded)
The kind of transformation the quadrilateral underwent is 180° rotation about the origin and the new vertex of Q is (4,5).
<h3>What is transformation of plane shapes?</h3>
Transformation is the change in the coordinates of the vertices that make up a plane shape.
This can be done either by translation, reflection or rotation.
Analysis:
since the x and y coordinates of P is the opposite of the coordinates of p' then there is a 180° rotation about the origin.
If vertex Q is (-4, -5), then Q' is the opposite which is (4, 5 )
In conclusion, the transformation is a 180° rotation and the coordinates of Q' are (4, 5).

(-6m^7 + 20m^6) = 2m^4(-3m^3 + 10m^2)
Therefore, (-6m^7 + 20m^6) ÷ 2m^4 = -3m^3 + 10m^2
Answer: (1) 13/20 (2) 8 (3) Yes. They are proportional
<u>Step-by-step explanation:</u>
(1) 13 students take the bus.
33 - 13 = 20 students do not take the bus

(2)

(3)

All of the fractions simplify to the same number so they ARE proportional.
