Answer:
A.y=|x|+7
Step-by-step explanation:
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)

Answer:
126 degrees
Step-by-step explanation:
Every triangle equals to 180 degrees so all you have to do is add 26+28 which equals 54 then subtract that from 180 and there's your answer.
26+28 = 54
180-54 = 126

34.3 Km /h was her average velocity in km/h.
What is average velocity?
- The change in position or displacement (x) divided by the time intervals (t) during which the displacement happens is the definition of average velocity.
- Based on the direction of the displacement, the average velocity might either be positive or negative. Meters per second (m/s or ms-1) is the SI measure for average velocity.
- The displacement of a body, or the shortest distance it must go during a trip, is calculated as the displacement multiplied by the time interval over which it covered that distance.
average velocity = Displacement / time taken
V = d/ l
V = 10.3 Km/0.300m = 34.3Km

Answer:
C
Step-by-step explanation:
The answer to this problem is 3 11/12.
1.8 3/4= 8 9/12
2.4 5/6 = 4 10/12
if you minus the two numbers, you get 3 11/12.
