Answer:
w = -3/4 or -0.75
there is only one solution
Step-by-step explanation:
How exactley do you want me to do I would really like to help you!
-5=1+x/3
Subtract 1 from both sides
-6=x/3
Multiply both sides by 3
-18=x
Check:
1+ -18/3=1-6=-5. Works!
So the answer is x= -18
2) If we have 2 points K & M with their coordinates (x₁,y₁) & (x₂,y₂), the the distance of KM is given by the formula:
KM = √[(x₂-x₁)² + (y₂-y1)²] ; K(2,3) & M(5,1) (Given)
KM = √[(5-2)² + (1-3)²] ==>√(9+ 4) ==> KM = √13 (ANSWER D)
3) The coordinates are A(4,7) & B(-3,9). Follow & apply the same methodology as above:
AB =√[(x₂-x₁)² + (y₂-y1)²] ; A(4,7) & B(-3,9) (Given)
AB =√[(-3-4)² + (9-7)²] ==> AB = √[(-7)² + (2)²] ==> √(49+4) =√53 (B)

How to simplify : keep on dividing the numbers until you get to the lowest number.
EX: Simplify 36
What number goes into 36..... 9!
so 36/9
=4
