5x = 15
x = 3
3(3) - 5y = -16
9 - 5y = -16
5y = -16 - 9
5y = - 25
y = - 5
(3, -5)
Step-by-step explanation:
x=54
use pyth then the other line = 15
then 15÷90 = 9÷x
then x = 54
Answer: C
Step-by-step explanation: You want to find the square root of each number given. The square root of 400 is 20, and the square root of 100 is 10
|4x-9|=5x
subtract 4 to both sides
and that will give you
|-9|=x then the 9 turns positive because of the brackets
9=X
