6y+5x=8 x3y=-7 use substituion

UNO [17]

Substitution:

6y + 5x = 8
x + 3y = -7

x = -3y + 7

6y + 5(-3y + 7) = 8
6y - 15y + 35 = 8
-9y + 35 = 8
-9y = -27
-y = -3
y = 3

x = -7 + 9
x = 2

y = 3
x = 2

A Pentagon is transformed according to the rule R0, 180°. Which is another way to state the transformation?

postnew [5]

The another way to state the transformation would be $(x,y)>(-x,-y)$

Solution:

Rotation about the origin at $180^\circ$ : $R_{180^\circ}A \rightarrow O = R_{180^\circ} (x, y) \rightarrow (-x,-y)$

The term R0 means that the rotation is about the origin point. Therefore, (R0,180) means that we are rotating the figure to $180^\circ$ about the origin.

So, the transformation of the general point (x,y) would be (-x,-y) when it is rotated about the origin by an angle of $180^\circ$ .

Hence according to the representation, the expression would be $(x, y) \rightarrow (-x, -y)$ .
