Answer:
Look image below.
Step-by-step explanation:
I got it wrong.. here's the correct answer.
y = 2x - 1
Lets see something:
y = 2x - 1
y = f(x)
If we want to do translations in vertical we just have to add an constant, where postive moves it upward and negatives, downward
y = f(x) + c
y = f(x) - 1
y = 2x - 1 - 1
y = 2x - 2
Now let's see this translation to the right
If we want to translate it in horizontal we just have to add a constant inside the function, where positive moves it to the left, and negative to the right
y = f(x) - 1
y = f(x - 3) - 1
y = 2.(x - 3) - 1 - 1
y = 2x - 6 - 2
y = 2x - 8
We are going to start with the triangle that is labeled.
a triangle is equal to 180 degrees
So we have the first triangle labeled- MJL-50, MLJ-65
add those together then subtract by 180
65+50=115 subtract by 180
=65 degrees
Next triangle kinda already gave us some clues
JLK-70
and it states that JM=KL
we solved that it is 65
so all we have to do it solve fro JKL
65+70=135 subtract that by 180
=45- JKL
