F (x) = 4x ⇒ y = 4x
↓
x = 4y Divide by 4 on both sides
↓
x / 4 = y ⇒ Inverse function = x / 4
Answer
<span>A. (3a − x)(2b + y)
cause
</span><span> (3a − x)(2b + y) = 6ab + 3ay -2bx -xy (expand by using distributive property)</span>
2x+5y=619
x=10y-3
________
2(10y-3) +5y=619
20y-6+5y=619
25y=619+6
25y=625
y=625/25
y=25
x=10*25-3
x=250-3
x=247
The probability is 15.63%. Solution:
(1 + 4)! over (1! + 4! + 2 raise to 5)
=5/32
=.1563
=15.63%
