Answer:
infinite number of solutions
Step-by-step explanation:
Work with the second equation. Subtract 8x from both sides.
- 4y + 8x - 8x = -8x - 12 Collect like terms.
-4y = - 8x - 12 Divide by - 4
-4y/-4 = - 8x/-4 - 12/-4
y = 2x + 3
That is exactly the same line as the first given. There is an infinite number of solutions.
Jackson achieved national distinction for his performance in the War of 1812. In the Battle of Horseshoe Bend, he oversaw the destruction of 15 percent of the Creek population; the treaty that ended hostilities forced the Creek to cede over 20 million acres of their ancestral lands. Jackson is most remembered for his performance in the Battle of New Orleans, during which he led his troops to a decisive victory over the British after the Treaty of Ghent had been signed and hostilities had officially ended.

In December 1817, President James Monroe authorized Jackson to lead an offensive against the Seminole and Creek Indians in Georgia and Florida, sparking the First Seminole War. Jackson ordered his troops to destroy Seminole settlements, capture a Spanish fort, and execute two British citizens whom Jackson blamed for supporting the Seminoles against white people. In 1819, the Spanish ceded all of Florida to the United States in the Adams-Onís—or Transcontinental—Treaty.

The election of 1828 and the Bank War
The presidential election of 1828 pitted incumbent John Quincy Adams against Andrew Jackson. Adams was the candidate of the National Republicans, while the party that arose around Jackson became known as the Jacksonian Democrats, or simply, the Democrats.
Answer:
39-6a
Step-by-step explanation:
(4 - a) - 5(a - 7) Distribute the -5 throughout (a-7)
4 - a - 5a + 35 Combine like terms
4 + 35 - a - 5a
39 - 6a
Answer:
The value of second quantity is 27
Step-by-step explanation:
Inverse variation can be represented by the equation xy=k or 
i.e,
y varies inversely as x , if there is some nonzero constant k such that, xy =k or where x≠0 and y≠0.
Given: Two quantities vary inversely.
Let x be the first quantity and y be the second quantity if they vary inversely.
then, by definition of inverse variation;
.....[1]
Substitute the value of x=15 and y=18 to solve for k;
Multiply both sides by 15 we have;
Simplify:
k=270
now, find the second quantity y using same method when x=10.
then;
after substituting the value of x=10 and k=270 in [1] ;
Simplify:
y= 27
Therefore, the second quantity value i.e,y = 27
