M Is the midpoint of AB. If AB = 3x +14, and AM = 2x-1, find x and MB.
Answers:
x = 16
MB = 31
==================================================
Work Shown:
M is the midpoint of AB
This means AM is half as long as AB and AM = MB
Put another way, AB is twice as long as AM
AB = 2*AM
3x+14 = 2*(2x-1)
3x+14 = 4x-2
14+2 = 4x-3x
16 = x
x = 16
AM = MB
MB = AM
MB = 2x-1
MB = 2*16-1
MB = 32-1
MB = 31

Which of the statements is true?
It is wrong because 6^2 is 12.
It is correct.
It is wrong because the subtraction should have been done before the addition.
It is wrong because 57 - 48 is 11

i got this right on my quiz
Answer: it's wrong because subtraction comes before addition
Step-by-step explanation:
in the order of operations, there is PEMDAS
parentheses
exponents
multiplication
addition
subtraction
from multiplication to subtraction it does not matter which one you do first as long as you solve left to right so...
57-36+48
moving left to right you would do 57-36 first

During summer, when the snow melts, the water level of the Yukon River increases. If the water level of the river increased by 84 centimeters in 6 days, what is the water level increase rate in centimeters per day?
Answer:
14 cm per day
Step-by-step explanation:
To find the water level increase rate in cm per day, divide 84 by 6, since it increased by 84 cm in 6 days:
84/6
= 14
So, the water level increase rate in 14 cm per day
There are 4 quarters in 1 dollar the total number of dollars is a function of the number of quarters does this situation represent a linear or nonlinear function? Explain why
Answer:
sample answer: If you make a table of values, you can see that 4 quarters equal 1 dollar and 8 quarters equal 2 dollars. If you graph the data, you will see a straight line. Therefore, this situation represents a linear function with a constant rate of change of 1/4
Step-by-step explanation:
The situation is a representation of the linear function.
What is meant by linear function?A linear function is one that, when graphed, produces a straight line. Thus, non-linear functions are any non-linear functions. Although graphing is the quickest way to determine whether a function is linear or non-linear, we can also determine linearity from its input/output table or equation. A straight line on the coordinate plane is represented by a linear function. For example, y = 3x - 2 denotes a straight line on a coordinate plane and, as such, a linear function.Given that,
One dollar is divided into four quarters.
The total number of dollars is a function of the number of quarters.
Based on the information presented above, we can conclude that when the dollar represents y value and the quarter represents x value
As a result, the slope should be 1/4.
y = 1/4x should be the linear function.
Hence, As a result, we can conclude that the situation is a linear function.

Answer:
[tex]\boxed {d = 13}[/tex]
Step-by-step explanation:
Use the Distance Formula to help you find the distance between the two following points:
[tex]d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}[/tex]
(where [tex](x_{1}, y_{1})[/tex] represents the first point and [tex](x_{2}, y_{2})[/tex] represents the second point)
-Apply the two following onto the formula:
[tex](x_{1}, y_{1}) = (8, -7)[/tex]
[tex](x_{2}, y_{2}) = (-4, -2)[/tex]
[tex]d = \sqrt{(-4 - 8)^{2} + (-2 + 7)^{2}}[/tex]
-Solve for the distance:
[tex]d = \sqrt{(-4 - 8)^{2} + (-2 + 7)^{2}}[/tex]
[tex]d = \sqrt{(-12)^{2} + 5^{2}}[/tex]
[tex]d = \sqrt{144 + 25}[/tex]
[tex]d = \sqrt{169}[/tex]
[tex]\boxed {d = 13}[/tex]
Therefore, the distance is [tex]13[/tex].

Answer: the answer is d/f+3
sorry i couldnt find my work for this problem but i hope it helps !
An equation is formed of two equal expressions. When in the given equation the value fo b is d/(f+3).
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
fb + 3b = d
Take b as a common term from both the terms on the left side of the equation,
b(f + 3) = d
Divide both the sides of the equation by (f+3),
b(f + 3)/(f+3) = d/(f+3)
Simplify,
b = d/(f+3)
Hence, when in the given equation the value fo b is d/(f+3).
