Answer: 
The distance between the coordinates of the two points is measured by the Distance formula
Step-by-step explanation:
The distance between two points P(x1,y1) and Q(x2,y2) is measured by Distance formula i.e Distance= 
(x2-x1)²+(y2-y1)²
So, the distance between the two points P(5,-3) and Q(2,4) can be measured by
Distance PQ = (2-5)²+(4-(-3))²
PQ = (-3)²+7²
PQ= 9+49
PQ=58
So,the distance of PQ is
Answer:
4
Step-by-step explanation:
at x=3
since x=3 means x>= 1
use x+1 = 3+1=4
Answer:
No, not a function
Step-by-step explanation:
Functions cannot have two or more same domain and different range. (3,3) and (3,9) have same domain and different range.
The inside of the radical must be greater than or equal to zero. When you plug in c=3, the answer is 5 >0. When c=-6, -4 <0. Therefore c=3 is true.
Answer:
g=9
Step-by-step explanation:
Add 1 to both sides of the equation t get 3.1(g-7)=6.2
Then divide both sides by 3.1 to get g-7=2
Then add 7 to both sides to get g=9
