Use cross products to demonstrate whether the two ratios are equivalent: four-sixths and fourteen over twenty-one
4/6 = 14/21
4*21 = 6*14
yes
reduce all fractions to lowest terms and compare them:
4/6 can be reduced to 2/3
14/21 can be reduced to 2/3
The ratios are equivalent.
2OI9!!!
oh, how I miss you!!
2O2O decided to show up and ruin the world. Man in fact 2O2O is almost gone! 2O2I is on its way! hopefully, things will be better then. But who knows. Anyways we miss you 2OI9!! Not to offend 2O2O but you were better than 2O2O. Like wayyy better
(okay dont mind me having a conversation with a year.. specifically 2019)
Thanks dude! could you help me with this one and then that's it.
Find the coordinates of quadrilateral V' W' X' Y' after a dilation with the scale factor of 2.
Original coordinates:
V(6, 2), W(–2, 4), X(–3, –2), Y(3, –5), scale factor of 2
no you gave the right ones...thanks!!!
just multiply all the coordinates by the scale factor: 2
V' = (12,4)
and so on
