Answer:
x = 14
y = 40
Step-by-step explanation:
3y+8 = 128
3y = 120
y = 40
45/20=2.25 (scale factor)
5x-25 = 2.25(2x-8)
5x-25 = 4.5x - 18
.5x = 7
x=14
Answer:
In mathematics, a set is closed under an operation if performing that operation on members of the set always produces a member of that set. For example, the positive integers are closed under addition, but not under subtraction: 1 − 2 is not a positive integer even though both 1 and 2 are positive integers.

Answer:
Step-by-step explanation:
m = 19 ; (-1,0)
y - y₁ = m (x - x₁)
y - 0 = 19 (x - [-1] )
y = 19 ( x + 1 )
y = 19x + 19
