Answer:

-49

Step-by-step explanation:

rule of thumb: whenever you have two negatives, they equal a positive! when you have one negative and one positive, it is a negative!

  1. let's start by going from left to right :))
  2. -24 -(-6) + (-31)
  3. -(-6) is actually + 6!
  4. -24 + 6 + (-31)
  5. +(-31) would be -31 because one - and one + is a -
  6. -24 + 6 - 31
  7. -18 - 31
  8. -49

What is the equation in slope-intercept form of the line that passes through the points (−26, −11) and (39, 34)?
Scrat [10]

The equation in slope-intercept form of the line passing through the given points is: C. y = \frac{9}{13}x + 7

<u>Given the following points:</u>

  • Points on the x-axis = (-26, 39)
  • Points on the y-axis = (-11, 34)

To find the equation in slope-intercept form of the line passing through the given points:

Mathematically, the equation of slope is calculated by using this:

Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}

Substituting the given points, we have:

Slope. \;m  = \frac{34 - [-11]}{39 - (-26)}\\\\Slope. \;m  = \frac{34\; + \;11}{39 \;+ \; 26}\\\\Slope. \;m  = \frac{45}{65}\\\\Slope. \;m  = \frac{9}{13}

The standard form of an equation of line is given by the formula;

y = mx + b

Where:

  • x and y are the points.
  • m is the slope.
  • b is the intercept.

We would find the intercept:

-11 = \frac{9}{13}(-26) + b\\\\ -11 = -18 + b\\\\b = -11 + 18

Intercept, b = 7

The equation in slope-intercept form of the line is:

y = \frac{9}{13}x + 7

Mrs. Jefferson would like to wallpaper a wall in her guest room. She would like to wallpaper everything but the door. Each roll
Vanyuwa [196]

Answer: Mrs. Jefferson should plan to spend 119.1 on wallpaper

Step-by-step explanation:

She would like to wallpaper everything but the door. It means that the area to be covered by the wallpaper would be the area of the 4 walls of the room - the area of the door.

The room is 18ft in length and 12ft in width. Thea area of each side of the room is

18 × 12 = 216 square feet

Area of the 4 sides of the room is

216 × 4 = 864 square feet

The door is 7ft in width and 3 ft in length. Area of door is

7 × 3 = 21 square feet

Area to be covered is

864 - 21 = 843 square feet

Each roll of wallpaper covers approximately 160 square ft. Therefore, the number of rolls needed is

843/160 = 5.26

Since the rolls cannot be a fraction, then she needs 6 rolls

Since a roll costs 19.85, the cost of 6 rolls is

19.85 × 6 = 119.1

(Matrix equation)(look at the picture) solve for x in the following matrix equation.
goldenfox [79]

Two matrices are the same if the entries of the two matrices in the same row and column are the equal.

For this equation to hold, we need

5x - 8 = 2

5x = 10

x = 2
