For the first option, since when x is going down (to the left) the function is going up, it's not approaching 0. For the second option, since when x is going up (to the right) it's going up, it's not approaching negative infinity (negative infinity is all the way down). For the third one, since when x is going down the y values are climbing, we can assume that the function's values go to positive infinity. For the last one, since when x=0 y=0, when x=0 the function does not go to infinity
First of all, recall that 1.5m is the same as 150cm.
Now, we simply build a proportion where we consider 48 to be 100, and wonder what 150 will be:
Solving for x, we have
Which actually makes sense, because we're stating that 1.5m is about 300% of 48cm, which means three times as much. Which is true, because three times 48cm means 144cm, which is about 1.5m
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>
