Answer:
The solution to the given system of equations is (-2,)
Therefore the values of x and y are x=-2 and
Step-by-step explanation:
Given equations can be written as
Solving equation(2) we get
x=-2
Substitute x=-2 in equation (1) we get
Therefore the values of x and y are x=-2 and
The solution to the given system of equations is (-2,)
Answer: "Use the straightedge to draw a line through points X and Y." is the right answer.
Step-by-step explanation:
To perpendicular bisector of line segment AB. There are following steps:
1) Draw arcs from points A and B on the both sides of AB.
2) Name the intersection points as X and Y.
3) Use the straightedge to draw a line through points X and Y.
4) Name the point as O
hence we have construct perpendicular bisector XY of AB which bisects at O.
Answer:
Step-by-step explanation:
Let, the number of cans collected by Shane = x.
So, the number of cans collected by Abha = x + 178.
Since, at least 2000 cans are required to be collected.
Thus, we have the inequality,
Number of cans by Shane + Number of cans by Abha ≥ 2000.
i.e.
i.e.
Thus, the required inequality is .
