Answer:
x=9 and angle B=40
Step-by-step explanation:
5x-5=3x+13
Subtract -3 on both sides of x
5x(-3)-5=3x(-3)=+13
2x-5=13
Add 5 to both sides
2x-5(+5)=13(+5)
2x=18
Divide by 2
x=9
Now that you know x=9, plug it into 3x+13
So, 3(9)+13= 27+13= 40
so ya thats my answer hopefully it helps
(btw both angle A and B are the same so thats why u put them equal)

Answer:
y = |x| -13
Step-by-step explanation:
recall for any function y = f(x), to translate the function vertically by any value "a", we simply have to add "a" to f(x).
If a is positive, then the graph is translated in the positive y-direction (i.e upwards), if a is negative, then the graph is translated in the negative y-direction (i.e downwards)
In our case , the graph is translated vertically by 13 units (i.e a = 13) and it is to be translated downwards (i.e negative)
hence we add a= -13 to the original function.
y = f(x) + (-13)
y = |x| + (-13)
y = |x| -13
