Answer: -1.13
Step-by-step explanation: I counted from -1.1 to -1.15
Answer:
49
Step-by-step explanation:
x + 100 + 31 = 180
x + 100 + 31 - 100 - 31 = 180 -100 -31
x = 49
Answer:
The first one, the one with A' at -4,5
Step-by-step explanation:
To find which graph shows the translation you first find a point that is easy to follow, ideally one that is along an axis.
Point A would be easy to follow, since it's roughly at (0,3) initially.
Then we apply the translation. T (-4,2) means the X value is moved to the left, subtracted 4 units... while the Y value is moved up, adding 2 units.
So, the point A that was at (0,3) becomes A' at (0 - 4, 3 + 2), or (-4,5).

X=23
I say this because you can see that the scale factor is 3 due to just visually scaling both the long and short leg from the original triangle to the dilated triangle. Dividing 39 by 3 is 13, and doing it in reverse. Adding 10 would equal 23, the initial value. So that'd be the missing value.
