b. 1.875 ÷ 500 = 0.00375. so that is your answer

Which graph shows the solution set of the compound inequality 1.5 x minus 1 greater-than 6.5 or 7 x + 3 less-than negative 25?

saul85 [17]

Answer:

After solving the compound inequality $1.5x-1>6.5 \ or \ 7x+3$ we get $\mathbf{x>5 \ or \ x$

Option B is correct.

Step-by-step explanation:

We are given compound inequality: $1.5x-1>6.5 \ or \ 7x+3$

We will first solve the inequalities to find the value of x, then will draw the graph.

$1.5x-1>6.5 \ or \ 7x+36.5+1 \ or \ 7x+3-37.5 \ or \ 7x\frac{7.5}{1.5} \ or \ x5 \ or \ x< -4$

So, after solving the compound inequality $1.5x-1>6.5 \ or \ 7x+3$ we get $\mathbf{x>5 \ or \ x$

Now, the number line will be as shown in figure.

The description as given in options is:

A number line goes from negative 10 to positive 10. An open circle appears at negative 4 and positive 5. The number line is shaded from negative 4 toward negative 10. The number line is also shaded from positive 5 toward positive 10.

so, Option B is correct.
