Answer:
A) {(1, 2), (1, 3), (1, 1)}
Step-by-step explanation:
The x variable repeats in (1,2), (1,3), (1,1) not making it a function.
X root 3 = 24 so x=8 root 3. that's the length of half a side. 16 root 3 is a full side, so the perimeter is 48 root 3.
Three equations are:
2x+1=6x+3
8x+6=2x+3
8x+4=2x+1
<u>Step-by-step explanation:</u>
Using the digits 0-9, no more than one time each, place a digit in a box to create an equation with a solution x= -1/2 . We need to Create three equations. Formula is below. __ x+ __=__ x+ __ . Let's find out:
2x+1=6x+3
Let's verify this :

Answer:
9d + 7
Step-by-step explanation:
(6d + 5) - (2 - 3d)
= (6d - (-3 d))+ (5 - 2)
= (6d + 3d) + 3
= 9d + 3
