I WILL GIVE BRAINLIEST, 5 STARS AND THANKS!!! When an inequality models a practical problem, why might some of the points on the
graph not be solutions to the problem even though they are solutions to the inequality?
1 answer:
Answer:
An inequality often covers an infinite area. Depending on the problem, any area either below or above the function is included in the set of solutions.
For example, see the attached photo.
y < x is graphed here.
When you substitute x = 0 into the function, y will equal 0 and this point is a solution to the problem. However, if any point under this line, such as (1, 0), (-9, 0), or even (1000000000, 0), was chosen, these are still solutions to the inequality, but not the problem.

Answer:
x = 1/2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 2 from both sides.
Step 3: Divide both sides by -4.
Answer:
A Only (2, 3)
Step-by-step explanation:
The given equation is in point-slope form:
y -k = m(x -h) . . . . . a line with slope m through point (h, k)
The point in the given equation is ...
(h, k) = (2, 3)
so you know the equation is satisfied at that point.
__
When you try the other point, you find ...
For (x, y) = (3, 2), you have
2 -3 = 5(3 -2)
-1 = 5(1) . . . . FALSE
Point (3, 2) does not satisfy the equation.
Only (2, 3) is a solution of the equation
_____
Of course, the equation of a line is satisfied by an infinite number of points. Of the two listed here, only (2, 3) is a solution.
