Answer:
8 ≥ x+3 or x ≥ 12
Step-by-step explanation:
The sum of a number (additon) and 3 (x+3) is no more than (so less than or equal to eight) OR is more than 12 ( x is more than 12, x ≥ 12 )
So the error is 1 mile
I ask what % of 15.5 = 1
How you write this;
x/100 *15.5 = 1
15.5x = 100
x = 100/15.5
x = 6.451629 round up 6.45
% error is 6.45 %
Question:
13 + b > 34
<em>Step 1: Keep variable on one side, and subtract 13 on both sides.</em>
b > 21
<em>Step 2: Now that you have the value of b, create a number line that includes the number "21"</em>
<em />
<em>Step 3: Since it is not "or equal too" we will use an open dot, since we do not contain that point. Put dot over 21. </em>
<em />
<em>Step 4: The sign is ( > ) meaning greater than. Therefore all points greater than 21 is </em><em>true</em><em>. See graph. </em>

<em>For another information, when D > 0, there are 2 real roots.</em>
<em>When D = 0, there is only one real root.</em>
<em>And when D < 0, there are no real roots (also known as imaginary.)</em>
