The student should have filled in the point w = 5 on the graph. The student shaded the values on the wrong side of the point w = 5. The student should have filled in the point w = 5 on the graph and he or she shaded the wrong values. The student did not make any errors. 26 What inequality is represented by the graph? w < 5 w < 5 opyright by Pearson Education Page 7 of 9

No; if you graph both inequalities on the same number line, you will cover all real numbers. No; if you solve the first inequality for b, you will end up with an inequality with a different relation symbol than the second inequality. No; if you graph both inequalities on the same graph, you will get b = ecide whether the two inequalities are equivalent. Explain. ; Yes; if you solve the first inequality for x, you will end up with the second inequality. No; if you graph both inequalities on the same number line, you will cover all real numbers. No; if you graph both inequalities on the same graph, you will get x = 14. No; if you solve the first inequality for x, you will end up with equivalent to., which is not 29 ecide whether the two inequalities are equivalent. Explain. ; Yes; if you solve the first inequality for z, you will end up with an inequality equivalent to the second inequality. No; if you graph both inequalities on the same number line, you will cover all real numbers. No; if you solve the first inequality for z, you will end up with an inequality with the variable on the wrong side. No; if you graph both inequalities on the same graph, you will get. 30 Your cousin s birthday is this weekend. You want to buy a that costs $12.99 and a birthday card that costs $2.50.
