Answer:

3B - 4C = \left[\begin{array}{cc}-8 &-23\\1&-15\end{array}\right]

Explanation:

Given

B = \left[\begin{array}{cc}8&-5\\-1&3\end{array}\right]

C = \left[\begin{array}{cc}8&2\\-1&6\end{array}\right]

Required

Determine 3B - 4C

If

B = \left[\begin{array}{cc}8&-5\\-1&3\end{array}\right]

Then

3B = 3 * \left[\begin{array}{cc}8&-5\\-1&3\end{array}\right]

3B = \left[\begin{array}{cc}24&-15\\-3&9\end{array}\right]

Similarly,

If

C = \left[\begin{array}{cc}8&2\\-1&6\end{array}\right]

Then

4C = 4 * \left[\begin{array}{cc}8&2\\-1&6\end{array}\right]

4C =  \left[\begin{array}{cc}32&8\\-4&24\end{array}\right]

So:

3B - 4C = \left[\begin{array}{cc}24&-15\\-3&9\end{array}\right] - \left[\begin{array}{cc}32&8\\-4&24\end{array}\right]

This gives:

3B - 4C = \left[\begin{array}{cc}24 - 32 &-15-8\\-3-(-4)&9-24\end{array}\right]

3B - 4C = \left[\begin{array}{cc}-8 &-23\\1&-15\end{array}\right]

President Franklin Roosevelt had issues with the Supreme Court when it found some of his programs unconstitutional. In an attemp
Lunna [17]

Answer:  the first election returns reached his family estate in Hyde Park, New York, on a November night in 1936, Franklin Delano Roosevelt leaned back in his wheelchair, his signature cigarette holder at a cocky angle, blew a smoke ring and cried “Wow!” His huge margin in New Haven signaled that he was being swept into a second term in the White House with the largest popular vote in history at the time and the best showing in the electoral college since James Monroe ran unopposed in 1820.

The outpouring of millions of ballots for the Democratic ticket reflected the enormous admiration for what FDR had achieved in less than four years. He had been inaugurated in March 1933 during perilous times—one-third of the workforce jobless, industry all but paralyzed, farmers desperate, most of the banks shut down—and in his first 100 days he had put through a series of measures that lifted the nation’s spirits. In 1933 workers and businessmen marched in spectacular parades to demonstrate their support for the National Recovery Administration (NRA), Roosevelt’s agency for industrial mobilization, symbolized by its emblem, the blue eagle. Farmers were grateful for government subsidies dispensed by the newly created Agricultural Adjustment Administration
