Graph the inequality on the number line.
1 answer:
Answer:
The inequality is shown in figure attached.
Since z < 11 , so there will be an open circle on 11 and number line will be shaded (arrow) on left side of 11.
Step-by-step explanation:
We need to graph the inequality z< 11
The inequality is shown in figure attached.
Since z < 11 , so there will be an open circle on 11 and number line will be shaded (arrow) on left side of 11.

Answer:
B
Step-by-step explanation:
Let y = f(x) and rearrange making x the subject
y = x² + 7 ( subtract 7 from both sides )
y - 7 = x² ( take the square root of both sides )
± = x
Change y back into terms of x, thus
(x) = ±
