Katniss Everdeen found the absolute value of |25| to be -25.
Do you agree? Yes or No
Explain:

Answers

Answer:

No

Step-by-step explanation:

Absolute values will never be negative.

Since absolute values are simply the number's distance from zero, it can never be negative, since there are no negative distances.

In this case, | 25 | is equal to 25. This is because the distance from 0 to 25 is 25.

So, Katniss is wrong.

Write the equation y+5=-10(x-1) into standard form

Answers

Answer:

10x + y = 5

General Formulas and Concepts:

Pre-Algebra

Equality Properties

Algebra I

Point-Slope Form: y - y₁ = m(x - x₁)  

x₁ - x coordinate y₁ - y coordinate m - slope

Standard Form: Ax + By = C

Step-by-step explanation:

Step 1: Define

Point-Slope Form:   y + 5 = -10(x - 1)

Step 2: Find Standard Form

Distribute -10:                              y + 5 = -10x + 10Add 10x on both sides:               10x + y + 5 = 10Subtract 5 on both sides:           10x + y = 5

And we have our final answer!

A 3-yard roll of wrapping paper costs $13.14. What is the price per foot?​

Answers

Answer:

Step-by-step explanation:

1 yard is equal to 3 feet.

since you have 3 yards, it'll be 9 feet.

13.14/9 to get your answer

or $1.46 per foot

The price per foot of wrapping paper is $1.46.

First, we need to convert 3 yards to feet. There are 3 feet in 1 yard, so 3 yards is equal to 3 * 3 = 9 feet.

The price per foot is simply the total price divided by the number of feet. In this case, the total price is $13.14 and the number of feet is 9, so the price per foot is:

price per foot = $13.14 / 9 feet

= $1.46 per foot

Therefore, the price per foot of wrapping paper is $1.46.
