Evaluate y = 4x - 1 when x = 10.

y=4*10-1

y=39

you just need to replace the x with 10

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)

step-by-step explanation:

1. 3

2. 4

3. 1

hope this ! have a great day.
