First combine like terms.

(16a + 20a) - 18b

What the slope formula represents
Anna [14]
The slope formula is y=mx+b. Y is a variable. m is the actual slope. It tells you how much the x will move. For example, if a slope was 2x, x would move up 2 and over 1. If the slope was 1/2 x, x would move up 1 and over 2. A way to remember slope is rise over run. X is a variable. B is a point on the y-intercept that is will the line will start. An example is y=x+3. The y-intercept is 3 and x would move up one and over one.

storchak [24]

Another word that has horizontal line symmetry is "book" and it is possible to form words with vertical line symmetry.

<h3>What is horizontal line symmetry in letters?</h3>

This implies that by dividing the letter in half using a horizontal line both sides would be the same. Lettters with horizontal line symmetry include:

  • H
  • K
  • O
  • E
  • B
  • C

<h3>What are some words with these symmetry?</h3>
  • Hood
  • Book
  • Cook
  • Bee

<h3>Are words with vertical line symmetry possible?</h3>

Answer:

Length of arc = 5 cm (Approx)

Step-by-step explanation:

Given:

Radius of circle = 20 cm

Angle = 1/4 radian

Find:

Length of arc

Computation:

Angle in degree = 1/4 radian × 180°π

Angle in degree = 1/4 × 180°  / 22/7

Angle in degree = 14.31° Approx

Length of arc = (Ф / 360)2πr

Length of arc = (14.31 /360)2(22/7)(20)

Length of arc = 4.997 cm

Length of arc = 5 cm (Approx)
