AB + BC = AC <em>Segment Addition Postulate</em>
(x + 10) + (x + 14) = 22 <em>Substitution</em>
2x + 24 = 22 <em>Simplify (added like terms)</em>
2x = -2 <em>Subtraction Property of Equality</em>
x = -1 <em>Divison Property of Equality</em>
Answer: x = -1
Gradient of AB = y1-y2/x1-x2
= -3-0/1-1
= -3/0
gradient of AB = gradient of CD (as AB is parallel to CD)
therefore D = 3+y3/0+x3
= -3+2/0+4
= -1/4
since y/x of D = -1/4,
the coordinates of D is (4,-1) [option B]

Hello!
First, let's find 6.2% of 98.5, and then add that price.
98.5(0.062)≈6.11
Now we add.
98.5+6.11= 104.61
Therefore, our final cost would be $104.61.
I hope this helps!
Step-by-step explanation:
y = 4x²+ 40x+112 (:4)
x²+ 10x+ 28.
<u>28</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>
1. |. 28
2. |. 14
4. |. 7
(x+4)(x+7)=0
x= -4. V. x= -7
Now fill in the x= -4 in y so you get the Y-coordinate and do the same for x= -7
Anseer should be like: 'The coordinates are (x, y) and (x, y)
