Answer:
friend this is not a formula
Step-by-step explanation:
ax ± b = c. All problems like the following lead eventually to an equation in that simple form.
Jane spent $42 for shoes. This was $14 less than twice what she spent for a blouse. How much was the blouse?
Solution. Every word problem has an unknown number. In this problem, it is the price of the blouse. Always let x represent the unknown number. That is, let x answer the question.
Let x, then, be how much she spent for the blouse. The problem states that "This" -- that is, $42 -- was $14 less than two times x.
Here is the equation:
2x − 14 = 42.
2x = 42 + 14
= 56.
x = 56
2
= 28.
The blouse cost $28.
It would be 42,523 because 50x10=500 and 5 in 42,523 is in the hundreds spot
A function is a relationship with a quantity (number). For example, if you made a table, and had one side be 1 2 3 4 5 (X axis) and then the y axis (other side) be 5, 10, 15, 20, 25, the function (rule) would be y= x5. The vertical line test is used to see if a graph has a function or not, so if it creates a vertical line on a graph, it has a function.
A real life situation would be miles per hour, so, for the x axis (hours) it said 1, and for the y axis (miles) it would be 60, this means in a duration of 1 hour you went 60 miles. Well, lets say you went 2 hours driving, the miles would be 120.
For 3 hours, it would be 180. The function here is y= x60!

Answer:
144, would be your answer
Step-by-step explanation: Multiply 144 by 9 and you get 1296.
Answer:
0.6
Step-by-step explanation:
The x increases by 5, while y increases by 3
Lets use the method, which is .
Keep in mind that x goes horizontally along the axis, while y goes vertically on the axis.
So plug the numbers in.
0.6
Hence, the constant proportionality is 0.6.
