Question 18
The answer is 4 days.
Because,
Kevin =3×n
Anita =4+ (2×n)
Equating the two equations.
3n=4+2n
3n-2n=4
n=4
Question 19
When the solution is (4,1), it means the value of y=1 and x=4.
The answer is;
y=x-3
y=-3x+13. Since when the values of x and y are substituted they satisfy the system.
Question 20
The system has no solution.
This is because the line are parallel and they do not intersect to give a solution.
Answer:
it is C. Q3- Q1 tell me if it was right or not
OR if it is for a listing order it would be this List in ascending order:-
32 39 45 48 50 57 65 68 70
Q1 = (39+45)/2 = 42
Q2 = 50
Q3 = (65+68)/2 = 66.5
Correct option is the first one if there are choices
Answer:
undefined
Step-by-step explanation:
The slope formula tells you the slope is ...
m = (y2 -y1)/(x2 -x1)
Fill in the point coordinates, we find the slope to be ...
m = (6 -9)/(-5 -(-5)) = -3/0
This slope is undefined.
___
It means the line is a vertical line. The constant must match the x-coordinates of the points:
x = -5 . . . . the line through the given points
