Answer: The slope is −2/3

Step-by-step explanation:

2 x + 3 y = 12  is the standard form for a linear equation. To determine the slope, solve the equation for  y  in order to convert to the slope-intercept form  y = m x + b , where  m  is the slope and  b  is the y-intercept.

2 x + 3 y = 12  

Subtract  2 x  from both sides.

3 y = − 2 x + 12

Divide both sides by  

3 . y = − 2 /3 x + 12 /3 =

y = − 2 /3 x + 4

The slope is  

− 2 /3

Identify the slope and y-intercept of the function y = -2x + 3. O A. The slope is 3. The y-intercept is (0,2). OB. The slope is
monitta

Since the slope-intercept form of a line is given by the expression:

y=mx+b

Where, m is the slope and b is the y-intercept.

Then, for the function:

y=-2x+3

The slope is -2 and the y-intercept is (0, 3)

The measures of ∠1, ∠2, and ∠3 are 40%, 12.5%, and 25% of the sum of the angle measures of the quadrilateral. Find the value of
sweet [91]

The value of x is 81

Step-by-step explanation:

The sum of the interior angles of any quadrilateral is 360°

  • The measure of ∠1 is 40% of the sum of the angle measures of the quadrilateral
  • The measure of ∠2 is 12.5% of the sum of the angle measures of the quadrilateral
  • The measure of ∠3 is 25% of the sum of the angle measures of the quadrilateral
  • We need to find the value of x

∵ The figure have 4 sides

∴ The figure is a quadrilateral

∵ The sum of the measures of the interior angles of a

    quadrilateral is 360°

- Add the four angles and equate the sum by 360

∴ m∠1 + m∠2 + m∠3 + x = 360

∵ m∠1 = 40% of the sum of the angle measures of the quadrilateral

∴ m∠1 = 40% × 360 = \frac{40}{100} × 360 = 144°

∵ m∠2 = 12.5% of the sum of the angle measures of the quadrilateral

∴ m∠2 = 12.5% × 360 = \frac{12.5}{100} × 360 = 45°

∵ m∠3 = 25% of the sum of the angle measures of the quadrilateral

∴ m∠3 = 25% × 360 = \frac{25}{100} × 360 = 90°

- Substitute these values in the equation above

∴ 144 + 45 + 90 + x = 360

- Add the like terms in the left hand side

∴ 279 + x = 360

- Subtract 279 from both sides

∴ x = 81°

The value of x is 81
