91 +94. 91 is rounded to 90 and 94 is rounded to 90.
90+90=180
Multiply the given equation by 4/3. This is a positive number, so the sense of the inequality remains the same.
A. a > -21 1/3
_____
When solving inequalities, the rules of equality hold, except when multiplying or dividing by a negative number (and when applying certain functions). In those cases, the direction of the inequality must be reversed. As a simple example, consider the inequality
2 > 1
When this is multiplied by -1, you get
-2 < -1 . . . . . > has changed to <
Answer:
6a-6b
Step-by-step explanation:
(5a+a)+(2b-8b)
6a-6b
Since we want to find the value of <em>k</em><em> </em>where the limit exists, set both equations equal to each other. Then substitute <em>x</em> = -1 in for each equation to find <em>k</em><em>.</em>
<em></em>
1. Set both equations equal.
2. Substitute <em>x</em><em> </em>= -1.
3. Solve for <em>k</em><em> </em>by adding <em>k</em><em> </em>to both sides. Continue the process of solving the equation.
Thus, <em>k</em><em> </em>= -2. Check by graphing the function.
