Mathematics
1 answer:
chubhunter [2.5K]3 years ago
3 0
Y - 3 = X + 2 ...............….... (1)
2X - 1 = Y ........................... (2)

From (2),
2X - 1 = Y

Y = 2X - 1


Sub (2) into (1),
(2X-1) - 3 = X + 2

2X - 1 - 3 = X + 2

2X - X = 2 + 1 + 3

X = 6


Sub x=6 into (1),
Y = 2(6) - 1

Y = 12 - 1

Y = 11

Does the Commutative Property of Addition apply when you add two negative integers?
MAVERICK [17]

The commutative property of addition means we can add two integers in any order. So yes, It would still apply to two negative integers (for example, -2 + -3 and -3 + -2 both equal five)

oksano4ka [1.4K]
<span>A(t) = −(t − 8)2 + 535
You would like to find the maximum of this function:</span> −(t − 8)^2<span>This part is always negative or zero as a number squared cannot be negative and you multiply by -1:  Thus the maximum of this part MAX:</span>−(t − 8)^2=0  
<span>The max will be when t=8 and its value is 535
