Answer:

= - x^2 + 4x  - 14

Step-by-step explanation:

(2x^2+6x−7)−(3x^2+3x−1)+(x−8)​

= (2x^2+6x−7   )    −3x^2   -3x  +1     +   (x−8)​

= (2x^2+6x−7   )    −3x^2   -3x  +1     +   x−8​

= (2x^2+6x−7   )    −3x^2   -2x - 7

= 2x^2+6x−7       −3x^2   -2x - 7

= 2x^2+6x−7       −3x^2   -2x - 7

= - x^2 + 4x  - 14

Write an equation of a line in point-slope form with the
Ulleksa [173]

Answer: (y − 0) = -(1/6)(x − 6)  or y=-(1/6)(x-6)

Step-by-step explanation:

An equation in Point Slope form:  y − y1 = m(x − x1), where m is the slope and x1 and y1 are provided as a single point, (x1,y1).  We have slope(m) = -(1/6) and are given (6,0).  Therefore:

 (y − 0) = -(1/6)(x − 6)  (Point slope form)

y = -(1/6)(x-6)

Rewriting this into standard form, y = mx + b

y = -(1/6)x + 1

Answer: Pearl

Step-by-step explanation:

In step 2, she justified her step by the definition of vertical angles. However, angles AKL and GKB do not share a common side, meaning they are not adjacent angles.
