1.) X=-2
2.) 2x-y+4=0
Hope this helps! :))
When you multiply two numbers which have the same sign the answer is positive. Therefore multiply eight and three to get 24 and the answer is positive; therefor the answers 24.
The answer is A, not sure about the expression though. Sorry
We need to simpify the given expression. The given expression to us is ,
<u>Given </u><u>Expression</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Using </u><u>Identity</u><u> </u><u>:</u><u>-</u><u> </u>
<u>So </u><u>that</u><u> </u><u>:</u><u>-</u><u> </u>
<u>We </u><u>have</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Hence </u><u>the</u><u> </u><u>required</u><u> answer</u><u> is</u><u> </u><u>-</u><u>1</u><u>/</u><u>4</u><u>. </u>
The function is y = 640/ 4^x and the graph decreases exponentially from 640 (for x =0) and asymptotically approacdhes zero (when x becomes larger and larger). This is an exponential decay.
Answer: the last option of the list. The graph will show exponential decay
