180 degrees in a triangle. subtract the 2 know angles to get the third.
180-39-24=117
Answer:
See below
Step-by-step explanation:
The initial ordered-pairs are ![(x, y)](https://tex.z-dn.net/?f=%28x%2C%20y%29)
We have a rotation of 90 degrees counterclockwise with respect to origin
Note. Previously the points were
![A(-3, 4), B(-3, 0), C(-1, 3)](https://tex.z-dn.net/?f=A%28-3%2C%204%29%2C%20B%28-3%2C%200%29%2C%20C%28-1%2C%203%29)
After the rotation, we have
![A(-4, -3), B(0, -3), C(-3, -1)](https://tex.z-dn.net/?f=A%28-4%2C%20-3%29%2C%20B%280%2C%20-3%29%2C%20C%28-3%2C%20-1%29)
Thus, ![(x, y) \rightarrow (-y, x)](https://tex.z-dn.net/?f=%28x%2C%20y%29%20%5Crightarrow%20%28-y%2C%20x%29)
Then shifting horizontally to the right 2 units, we get ΔA'B'C'
Thus,
![(x, y) \rightarrow (-y, x) \rightarrow (x+2, y)](https://tex.z-dn.net/?f=%28x%2C%20y%29%20%5Crightarrow%20%28-y%2C%20x%29%20%5Crightarrow%20%28x%2B2%2C%20y%29)
Answer:
7.22
Step-by-step explanation:
57.76/8
X=2 y=4 substitute y=2x into x=-y+6 so it’s x=-2x+6 add the 2x on both sides 3x=6 divide by 3 x=2 and plug that into y=2x so it’s just 2x2 which is 4
The whole amount is 8, so that goes in the denominator( The bottom) He ate 1 of them, and so it is asking what fraction did he eat? Since he ate 1, you would put that on the numerator ( top) So the answer is 1/8.
