Answer:

AB || DC                               Given

∠ABE ≅ ∠CDB                    Alternate interior angles are congruent

BC || AE                                Given

∠CBD ≅ ∠BEA                     Alternate interior angles are congruent

ΔAEB is similar to ΔCBD    AA Similarity Postulate

BC / EA = BD / EB               Similar sides are proportional

F(x)=x2+5x-1 is shifted 3 units left the result is g(x) what is g(x)?
Len [333]
Replace the x in  x^2 + 5x - 1 by x+3:-

g(x) =
(x+3)^2 + 5(x+3) - 1

= x^2 + 6x + 9 + 5x + 15 - 1

= x^2 + 11x + 23

- thats  g(x)

Identify an equation in slope-intercept form the line parallel to y=-3x+7that passes through (2,-4)
gregori [183]

Answer:

y=-3x+2

Step-by-step explanation:

Same slope = parallel. You can aso double check this answer by either graphing using the desmos online graphing calculator or by plugging in the point into the equation y = -3(2) + 2 --> y = -6 + 2 --> y = -4, so we are correct.

NEED HELP WITH THESE
faltersainse [42]

Step-by-step explanation:

1 .f(x)=x^{2}-x+1

   f(-1)= (-1)-(-1)+1

   f(-1)= 1+1+1

      = 3

3.f(x)=x^{2}-x+1

 f( 1)=(1)-1+1

  f( 1)=1-1+1

        =1

5. f(x)=x^{2}-x+1

    f(3)=(3)^{2}-3+1

         = 9-3+1

          =7

2. g(x) = 5 - 3x

 g( -8)=5-3(-8)

g( -8)=5+24

        =29

4.g(x) = 5 - 3x

g(5)=5-3(5)

 g(5)=5-15

       =-10

6.g(x) = 5 - 3x

   g(-3)=5-3(-3)

 g(-3)=5+9

         =14
