Select the correct answer. Which graph represents a proportional relationship

1 answer:

6 0

If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate. For each point (x, y) on the graph, ž is equal to k, where k is the unit rate. The point (1, k) is a point on the graph.

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.

3 and 1/2=3+1/2=6/2+1/2=7/2

3/2dozen=7/2cups
times 2 both sides
3dozen=7cups
divide by 3 both sides
1dozen=7/3cups=2 and 1/3 cup

Answer:

24.7 feet

Step-by-step explanation:

This is a Pythagorean theorem question

The ladder is the hypotenuse or c

the distance from the wall is a leg or a

and the wall is the other leg or b

a² + b² = c²

a² + 17² = 30²

a² + 289 = 900

-289 -289

b² = 611

√ √

b = √611

b = 24.7 feet

A rectangle has a width, w, equal to 6 less than the length, l. Which expressions represent ways to find the perimeter of the re

Irina-Kira [14]

Answer:

4L-12

Step-by-step explanation:

let's assume the length = L

then the width of the rectangle is L - 6

perimeter = 2× (a+b)

where "a" and "b" are the length and the width of the rectangle.

so perimeter = 2× (L + L - 6)

2 × ( 2L - 6)

4L - 12

Electric current is the movement of the electrons caused by potential difference. For example, in a circuit, the electrons in the bulb will not move without the potential difference or voltage. When there is voltage, electric current occurs because there is a driving force for the electrons in the wire to move.
