Answer:
Part A: one solution:
Part B: x = 3, y = 4.
Explanation:
1) Part A: how many solutions does the pair of equations for lines A and B have?
The solution of a system of equations in a graph is given by the intersetion of the curves that represent the equations.
In this case, there are two straight lines, which intersect in one and only one point.
Hence, the system has one solution.
2) Part B: what is the solution to the equations of lines A and B?
The solution is the pair of coordinates of the intersection point. It is (3, 4).
Therefore, the solution is x = 3, y = 4.
Answer:
The dependent variable is the level of aggressiveness.
Step-by-step explanation:
This is a case were researchers exposed children to 2 hours of Tv with violence of without violence. The researchers what to know the level of aggressiveness. Analyzing the information you can see that the amount of time (each day per one moth during 2 hours) on the Tv and the violence or not violence exposition are controlled by the researchers so these ones are the independent variables. And the level of aggressiveness is the dependent variable because this one depend on the amount of time and kind of Tv program.
B is your answer because if u look at it the
Answer:
maybe number 2
Step-by-step explanation:
because if 2+k=18 then there is no other k there and where did the additional 2 come from ?and 2k=18 then value of k is 9 + there is balance.I may be wrong correct me but i think it is no.2
