title: What replaced appcompat-v7 in AndroidX
body: <p>After migrating a couple of my older projects over to AndroidX it as though three of my dependencies are deprecated:</p>
  
  <pre><code>   implementation 'com.android.support:appcompat-v7:28.0.0'
     implementation 'com.android.support:design:28.0.0'
     implementation 'com.android.support:cardview-v7:28.0.0'
  </code></pre>
  
  <p>I haven't been able to find a replacement for these dependencies. </p>
  
  <p>Does AndroidX have an equivalent for these dependencies?  </p>
