The missing value is 6.
Use the slope formula and equal it to -3. Solve for x.
1. 2
2. 14
3. 20
4. 56
if the : means something other than division then these r wrong sorry
Answer:
A)one solution (3, -3)
B)no solution
C)infinite solution
Step-by-step explanation:
A) The two equations intersect at a point. This point satisfies both equations.
B) The two equations are parallel and never intersect. Therefore no solution.
C) The two equations are stacked on top of one another. No matter with point of the like is chosen, the point will satisfy both equations.
1 * 7 + 2 * 1 + 3 * 3 + 4 * 2 + 5 * 2 =
7 + 2 + 9 + 8 + 10 =
36
Now we need to divide 36 by the total frequency: 7+1+3+2+2=15
36 / 15 = 2.4
