Answers

It will be 9x + 1 = 12x + 20.

The answer you’ll put in the box is 1, because it doesn’t ask you to solve for x, just fill in the number.

Answer:

The blank in the equation is 1.

x = 7 and the vertical angles measure out to 64 degrees.

Step-by-step explanation:

When solving for x, you always want to keep the variables on one side. So you'll subtract 9x from both sides. That gives you 1=3x-20. Then you'll add 20 to both sides. This gives you 21=3x. After you'll divide by 3 on both sides. This gives you 7=x.

Now you'll plug in 7 for x. This gives you 12*7-20=9*7+1. First, you'll multiply which gives you 84-20=63+1. Add and you'll get 64 on both sides.

What is the diagram?

Answers

Answer:

c/e = e/d

Step-by-step explanation:

These are similar triangles. When you flip the larger one clockwise to enable you to see which sides are corresponding, then you find that:

c corresponds to e'

a corresponds to b

e corresponds to d

Therefore, c/e in the original position = e'/d in the flipped position.

So c/e = e/d

Graph the line with a slope of 2/3 that contains the point (−3,−5)

Answers

Answer:

Step-by-step explanation:

So for the given information, it would be easiest to use slope-intercept form, which is y=mx + b, where m is the slope and b is the y-intercept.

We can plug in 2/3 for the slope, because we are given that.

y=2/3x + b.

To find the y-intercept, plug in the given point for x and y and solve for b.

-5 = 2/3 · (-3) + b

-5 = -2 + b

b = -3

So now we have the complete equation of the line.

y = 2/3x -3

Now to graphing.

We can put the y-intercept, (0, -3), and the given point, (-3, -5) on a graph.

By about 2300 BCE, the large city of Harappa had been built. Harappa was one of the most developed civilizations in the world in its day. It included the city of Harappa and another big urban area, Mohenjo-daro, about 300 miles away on another section of river. Even though they were far apart, the two cities had striking similarities. Both were laid out with grids of paved streets that made right angles. People built houses out of stone, some of which were three or four stories high. Big fortresses stood near each city to provide protection. The people had weights, measures and a currency, so they could trade. The government may have stored food in case of shortages. They were perhaps the first people to make garments out of cotton. The Harappans used pictographs, drawings and symbols that represented ideas, to write. Both cities had another great invention: sewer systems to carry all human waste out of the city. Almost no other cities had a sewer system at this time. Harappan civilization had all but disappeared by 1700 BCE for reasons that are still unclear. The story of the Harappan civilization is most similar to which of the following?AIn Ancient Greece, the Mycenaeans made huge advances in engineering and architecture and had a written language. Their society collapsed for unknown reasons in 1100 BCE.BThe Incan empire did not have many technological advances but covered over 770,000 square miles before it was defeated by Spanish conquistadors in 1533.CThe Khmer Empire, in modern-day Cambodia, was an enormous Buddhist city with advanced systems of art and architecture.
