I believe the best answer choice is going to be D because if you think about it, when you buy gas both the price and gallonage go up. Hope this helps..

The <em><u>correct answer</u></em> is:

D) The amount a person pays for gas compared with the number of gallons purchased

Explanation:

A constant rate of change means that for every x, y increases the same amount.

In the situation "The amount a person pays for gas compared with the number of gallons purchased ," the independent quantity, or x-value, is the number of gallons, and the dependent quantity, or y-value, is the amount paid.  Since gas has a set price per gallon, for every gallon purchased, the total amount paid goes up the same amount.  This means it has a constant rate of change.

In triangle ABC, you know that a = 2, b = 3 and m &lt; A = 30°. Which option below lists the number of triangles and gives the c
zhenek [66]
Apply the Law of Sines.
sinB/b = sinA/a
sinB/3 = sin(30°)/2
sinB = (3/2)sin(30°) = 0.75

Therefore
bsinA = 3*sin(30) = 1.5
0.5b = 0.5*3 = 1.5

Answer:
There is exactly one triangle because b sinA  = 0.5b.

3 times a number plus 5 is the equal to the same number increased by 17. what is the number
kondor19780726 [428]

Answer:

The number is 6

Step-by-step explanation:

Let the number be x

3 times a number plus 5 =  3x +5

Same number increased by 17 = x + 17

3x + 5 = x + 17

3x -x  + 5 = 17

2x + 5 = 17

2x = 17 - 5

2x = 12

x = 12/2

x = 6
