1. find out many days are in a week (7)
thank subtract 1 from the week and then count every week friday i'm not sure if this is the correct answer but check your answer in case'
I think it is, (1,1) I think that is it...
8x - 9y = 11
Subtract 8x to both sides:
-9y = -8x + 11
Divide -9 to both sides:
y = 8/9x - 11/9
or
y = 8/9x - 1 2/9
Answer:Rigid transformations preserve segment lengths and angle measures.
A rigid transformation, or a combination of rigid transformations, will produce congruent figures.
In proving SAS, we started with two triangles that had a pair of congruent corresponding sides and congruent corresponding included angles.
We mapped one triangle onto the other by a translation, followed by a rotation, followed by a reflection, to show that the triangles are congruent.
Step-by-step explanation:
Sample Response: Rigid transformations preserve segment lengths and angle measures. If you can find a rigid transformation, or a combination of rigid transformations, to map one triangle onto the other, then the triangles are congruent. To prove SAS, we started with two distinct triangles that had a pair of congruent corresponding sides and a congruent corresponding included angle. Then we performed a translation, followed by a rotation, followed by a reflection, to map one triangle onto the other, proving the SAS congruence theorem.
