Answer:
A. x<31 and x > -5
Step-by-step explanation:
| X-13 |< 18
Seperate into 2 equations, one positive and one negative, remembering to flip the inequality for the negative
x-13 < 18 and x -13 > -18
Add 13 to each side
x-13+13 < 18+13 and x-13+13> -18+13
x < 31 and x>-5

Answer:
Larger number(x)=20
Step-by-step explanation:
They're saying that the larger number 3 times is EQUAL(the same) to 4 times the smaller number.
The smallest number=35-x.
The larger number= x.
3 times the larger number=3x
4 times the smaller number=4(35-x)
Now, input it into an equation and solve:
3x=4(35-x) Distribute by multiplying 4 with 35 and x.
3x+4x=140-4x+4x Get 140 by itself by adding 4x.
7x/7=140/7 Divide.
x=20
Since x= the larger number, x=20.
The reflection across x = -2 will be x = 2.
