All galaxies are held together by gravity, but based on what we can see (stars, nebulae, etc.) , there shouldn’t be enough gravity to do the job. That is why scientists believe that all galaxies are partially held together by a substance called _________________________________, which we can’t see.

Answer:

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

Explanation:

Given

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

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

Required

Determine 3B - 4C

If

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

Then

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

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

Similarly,

If

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

Then

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

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

So:

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

This gives:

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

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

Explanation:

Answer:

One rhetorical strategy Fredrick Douglas uses is parallelism; one example of him using this is when he says: "What he most dreaded, that I most desired. What he most loved, that I most hated." both of these sentences explain how they feel two different things, using opposite words. Another rhetorical strategy he uses is personification. One example of him using personification he says, "Under its influence, the tender heart became stone, and the lamblike disposition gave way to one of tiger-like fierceness." In this sentence, he beautifully personifies a heart.
