The slope of the line below is -2. Which of the following Is the point-slope form of a line? (4,-8)
Answers
Answer: A. y+8=-2(x-4)
Step-by-step explanation: Point-slope form is y-y₁=m(x-x₁), in which you only substitute three values: the slope, and the x and y coordinate. So, since the slope is -2, you replace it with m. And, if the point is (4, -8), you would substitute the 4 in for x₁, but the -8 is a little more complicated because it is negative. Basically, the negative and the minus sign cancel out and it becomes a plus sign.
Hope this helped! Good luck!

Answer:
Kevin is 7 years old right now.
Step-by-step explanation:
Let x be Kevin's age right now, that's what we're trying to find.
In 56 years, he'll be 9 times older than he is now, so we can say:
x + 56 = 9x
Now we can get the x values on the right side of the equation so that:
56 = 8x
Now solve for x and you have his current age which is 7.

A new bank customer with $3,000 wants to open a money market account. The bank is offering a simple interest rate of 1.9%. a. How much interest will the customer earn in 30 years? b. What will the account balance be after 30 years?
pls answer fast due in 10 minutes
Answers
Simple interest = Principal * Rate * Time
Here, the principal (P) is $3,000, the rate (R) is 1.9%, and the time (T) is 30 years.
Simple interest = $3,000 * 0.019 * 30 = $1,710
Therefore, the customer will earn $1,710 in interest over 30 years.
b. To calculate the account balance after 30 years, we can add the interest earned to the principal:
Account balance = Principal + Interest
Account balance = $3,000 + $1,710 = $4,710
Therefore, the account balance will be $4,710 after 30 years.
a. To calculate the interest earned in 30 years, we can use the simple interest formula:
Simple interest = Principal * Rate * Time
Here, the principal (P) is $3,000, the rate (R) is 1.9%, and the time (T) is 30 years.
Simple interest = $3,000 * 0.019 * 30 = $1,710
Therefore, the customer will earn $1,710 in interest over 30 years.
b. To calculate the account balance after 30 years, we can add the interest earned to the principal:
Account balance = Principal + Interest
Account balance = $3,000 + $1,710 = $4,710
Therefore, the account balance will be $4,710 after 30 years.
If the relationships below are given in the form (input, output), which pairing always describes a function? (a person’s age in years, that same person’s height in inches) (a person’s weight in pounds, that same person’s height in inches) (a person’s height in centimeters, that same person’s height in inches) (a person’s telephone number, that same person’s height in inches)
Answers
Answer:
A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:
(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.
(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.
(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.
(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.
So, the pairings that always describe a function are:
(a person’s age in years, that same person’s height in inches)
(a person’s weight in pounds, that same person’s height in inches)
(a person’s height in centimeters, that same person’s height in inches)
These three pairings meet the criteria of a function, where each input corresponds to a unique output.
The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)
How did we arrive at this assertion?A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:
1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).
2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.
3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.
4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).
So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)

A student made a mistake when measuring the volume of a big container. He found the volume to be 75 liters.However, the real value for the volume is 60 liters. What is the percent error?
Answers
Answer: 20%
Step-by-step explanation:
Explanation is in progress of writing:
First, I will divide 60 by 75 and multiply by 100, to find what percent of 75 is 60:
= \(\frac{60}{75}\) · 100
= 0.8 · 100
= 80%
The percentage error of the student's measurement is 25%.
Given the following data;
Experimental value = 75 liters Real value = 60 litersPercentage error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.
Mathematically, percentage error is given by this expression;
\(Perecent \; error = \frac{Real \; value - Experimental \; value}{Real \; value} * 100\)
Substituting the values into formula, we have;
\(Perecent \; error = \frac{60 - 75}{60} * 100\)
\(Perecent \; error = \frac{-15}{60} * 100\)
Note: The negative sign is neglected in percentage error.
\(Perecent \; error = \frac{1}{4} * 100\)
Percent error = 25%
Therefore, the percent error is 25%.

Answer:
Answer is -1.25
Step-by-step explanation:'
You start by making sure everything in the problem is a decimal which means turning 1 1/4 into 1.25 and then adding the two numbers together -2.5+.25=-2.25
-2.25+1=-1.25
Brainliest would be nice.
Answer: -3.125 or -25/8
Step-by-step explanation:
I do not know what has been covered in your class, but the "x" appears to be multiplication here.
It would be best to convert into all decimals or all fractions.
For all fractions (I think is easiest):
-2.5 is -2 1/2 = -5/2 and then 1 1/4 = 5/4 (need improper fractions to multiply, then multiply straight across)
Then take -5/2 * 5/4 = -25/8 (multiply fractions by multiplying numerators together, then denominators together). If you need this as a mixed number, -25/8 is -3 1/8
For all decimals:
-2.5 is already as a decimal, then 1 1/4 = 1.25
So then multiply:
1.25 (I put 1.25 first because it has more digits)
x -2.5 (note- multiplying a positive by a negative gives you a negative)
6 2 5 (multiply 5x5 first, giving 25, so place 5 and carry the 2,
then multply 5x2 = 10 plus the 2 carried is 12, carry that 1
then 5x1 = 5 plus the 1 carried is 6)
+ 2 5 0 0 (0 placeholder first, now multiply the 2 by each digit of 1.25,
2x5 = 10, carry the 1, then multiply 2x2 = 4 plus the 1 carried
is 5, then multiply the -2 by the 1 , -2x1 = -2)
Now add the 625 + 2500 = 3125, there were 3 digits after the decimal originally, so move decimal back 3 places, giving 3.125. Finally, the answer is negative because you multiplied a negative number with a positive one. SO the final answer is -3.125 (also equal to the -25/8)

Describe the transformation of g(x) as it relates to the parent function f(x).
Answers
Answer:
Hope this helps
Step-by-step explanation:
g(x)=f(x−h) g ( x ) = f ( x - h ) - The graph is shifted to the right h units. The vertical shift depends on the value of k . When k>0 , the vertical shift is described as: ... g(x)=f(x)−k g ( x ) = f ( x ) - k - The graph is shifted down k units.
The transformation of g(x) as it relates to the parent function f(x) is translated to 1 unit right. Therefore, option B is the correct answer.
What is a transformation?A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.
The given functions are f(x)= -4ˣ and g(x)=1/3 (-4ˣ).
To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.
Parent Function: f(x)= -4ˣ
Horizontal Shift: None
Vertical Shift: None
Reflection about the x-axis: None
Vertical Compression: Compressed
Therefore, option B is the correct answer.
