D、
E、
答案
C
解析
To determine which of the graphs is the correct answer, you first need to determine all values of x that satisfy the inequality. To do that you need to simplify the inequality until you isolate x.
You can begin by multiplying both sides of the inequality by 3 to obtain(3)(2 - 5x)
-(6x - 5). Note that when you multiply by 3, the right-hand side of the inequality becomes -(6x - 5),
not
-6x - 5.
The rest of the simplification is as follows.
Note that when an inequality is multiplied(or divided)by a negative number, the direction of the inequality reverses.
The graphs in the answer choices are number lines on which only the number 0 is indicated. Therefore, you do not need to locate 1/9 on the number line; it is nough to know that 1/9 is a positive number. Choice C is the only choice in which the shaded part of the line is equal to or greater than a positive number. Therefore, the correct answer is Choice C.
