Which of the following represent a linear inequality in open-sentence form? (Select all that apply.)

2x + 8 = 10y
2x - 7y > 10
8 + x > 5
3 < 5

Option C: is the linear inequality in open - sentence form.

Explanation:

We need to determine the linear inequality in open - sentence form.

The open - sentence form of an equation or inequality which contains one variable.

If we substitute the value of a variable in the open sentence then the equation or inequality can be either true or false.

If the inequality or equation is true then the number is the solution to the variable.

Hence, the linear inequality in open sentence form is

Therefore, Option C is the correct answer.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
