Solve first for the solution of the inequalities. This can be done by replacing first the inequalities sign with the equal sign.
x + y = 1
2y = x - 4
The values of x and y from the system of linear equation are 2 and -1. This means that the intersection of the lines should be at point (2, -1).
Substitute 3 to x and determine the value of y from the second inequality.
2y ≥ x - 4
Substituting,
2y ≥ 3 - 4, y ≥ -1/2
Hence, the solution to this item should be the fourth one.
Answer:
The answer is 1.35 answer (1). You can graph both equations to give you the answer.
Step-by-step explanation:
Graph the equations and see where they intersect.
Answer:if im right you need to do 54 divided by 2= 27 so 27+27=54
Step-by-step explanation:
Answer: x+8
The term 'sum' means 'result of adding two (or more) numbers or expressions'.
