< BOC and < BOF are supplementary and add up to 180
Answer:
Option 1: {-7,5,18,24,32}
Step-by-step explanation:
Observing the number line we can see that the solution is
x≤18 and x>22
So we will check the options one by one
For {-7,5,18,24,32}
The number set satisfies the solution translated from the number line.
For {-9,7,15,22,26}
As this number set includes 22 which is not included in the solution so this option is not correct.
For {16,17,22,23,24}
This number set also includes 22 so the option is not correct.
For {18,19,20,21,22}
This number set includes 19,20,21,22 which is not a part of the solution. Therefore, this option is also not correct ..
Answer:
x squared+4x−12
Step-by-step explanation:
Answer: {11, -11}
Step-by-step-explanation: To solve for <em>x</em> in this equation, since <em>x</em> is squared, we simply take the square root of both sides of the equation to get <em>x</em> by itself.
It's important to remember however that when taking the square root of both sides of an equation, we always use <em><u>plus</u></em> or <em><u>minus</u></em>.
In other words in this problem, since x² = 121,
<em>x = + or - 11</em>.
A common mistake is to say that <em>x</em> is just equal to 11. But notice that if you plug a -11 back into the original equation, it also checks.
So our answer to this problem is {11, -11}.
