B is the midpoint of AC. What is the value of x if AC = 52 and AB = 3x - 4
1 answer:
Answer:
x = 10
Step-by-step explanation:
Since B is the midpoint of AC then AB = BC = 3x - 4 and
AB + BC = AC , thus
3x - 4 + 3x - 4 = 52, that is
6x - 8 = 52 ( add 8 to both sides )
6x = 60 ( divide both sides by 6 )
x = 10

Answer:
using section formula, B(-3, -3)
Answer:
Zero is nor a positive or negative number, so im guessing the answer is 0.
Step-by-step explanation:
(-3,11) & (1,-3)
x1 y1 x2 y2
-3-11 -14 -7
1+3 4 2
y=-7/2x+b
11=-7/2(-3) +b
11=21/2+b
22/2=21/2+b (subtract 21/2 from each side)
1/2=b
so it would be y=-7/2x + 1/2
