Answer: x would have to equal 8

Step-by-step explanation: When a line intersects parallel lines it forms supplementary angles. The sum of two supplementary angles is 180°

We can use this information to set up an equation:

(6x -7 ) + (19x -13) = 180 . Combine like terms

25x -20 = 180 Add 20 to both sides.

25x = 200 Divide both sides by 25

x = 8

Check:

19(8) - 13 + 6(8) - 7 = 180

152 - 13 + 48 -7 = 180

139° + 41° = 180

The sum of the interior angles formed by the line is 180°, so lines a and b must be parallel.

Calculate Income Elasticity of Demand Question Suppose that when the price of cream cheese rises by 10%, the quantity of bagels

inn [45]

Answer:

eY is positive +0.1 therefore bagels are a normal good.

Step-by-step explanation:

Given data:

when, 10% rise in cheese price, 3% fall in bagels quantity observed

when, 10% rise in income, 1% fall in bagels quantity observed

from formula for cross price elasticity of demand, determine $e_{AB}$

$e_{AB} = \frac{(−3\%}{(10\%)} = −0.3.$

As, eAB is negative, bagels $ cream cheese are complements.

By formula for income elasticity of demand,

we find that $eY= \frac{(+1\%)}{(10\%)} = +0.1.$

Since eYis positive, bagels are a normal good.

Find the slope of the line through the points (−3, 6) and (2, 6).

Elden [556K]

Answer:

There wouldn't be a slope. It would be 0/5

Step-by-step explanation:

$\frac{6-6}{2+3}$

6 - 6 = 0

2 + 3 = 5

0/5 isn't a slope.

The price of some houses in a neighborhood are shown below: House Price A $120,000 B $130,000 C $140,000 D $150,000 E $1,110,000

LenaWriter [7]

Answer:

To infer a price for the houses in that neighborhood, it is better to use the median.

Step-by-step explanation:

We have the following prices:

$ 120,000

$ 130,000

$ 140,000

$ 150,000

$ 1,110,000

Now, if we do it for the median, it is the best option, because there is a very distant value and the median is not much affected. The value that is inferred through the average is $ 140,000, a value close to the first 4 houses.

If we do it by the mean, the value would be:

(120,000 + 130,000 + 140,000 + 150,000 + 1,110,000) / 5 = $ 330000

a value very far from all the prices of the houses, this is due to the value so far from the last house.

In other words, to infer a price for the houses in that neighborhood, it is better to use the median.
