NEED HELP. WILL MARK BRAINLIST. DO NOT SPAM
Tcecarenko [31]

Answer:

  a) x = {-2, 1, 3} are the zeros

  b) y = (x +2)(x -1)(x -3)

  c) y = x^3 -2x^2 -5x +6

Step-by-step explanation:

a) The zeros are the values of x where the graph crosses y=0. Those values are x = -2, x = 1, x = 3.

__

b) If "a" is a zero, then (x-a) is a factor. The factored polynomial is ...

  y = (x +2)(x -1)(x -3)

__

c) This can be multiplied out using the distributive property several times.

  y = (x +2)(x(x -3) -1(x -3))

  = (x +2)(x^2 -3x -x +3)

  = (x +2)(x^2 -4x +3)

  = x(x^2 -4x +3) +2(x^2 -4x +3)

  = x^3 -4x^2 +3x +2x^2 -8x +6

  y = x^3 -2x^2 -5x +6

_____

The supplied graph apparently scales this vertically by a factor of 1/2, since its y-intercept is at (0, 3), not (0, 6).

i did 16x50=800

i got 50 from <u>50</u> in 50000 and the 16 from <u>16.00 so then i times 16 from 50 which is 800</u>

Vertical and Adjacent Angles (3 Activities)<br> 100 POINTS+BRAINLIEST
Yakvenalex [24]

Answer:

Problem B: x = 12; m<EFG = 48

Problem C: m<G = 60; m<J = 120

Step-by-step explanation:

Problem B.

Angles EFG and IFH are vertical angles, so they are congruent.

m<EFG = m<IFH

4x = 48

x = 12

m<EFG = m<IFH = 48

Problem C.

One angle is marked a right angle, so its measure is 90 deg.

The next angle counterclockwise is marked 30 deg.

Add these two measures together, and you get 120 deg.

<J is vertical with the angle whose measure is 120 deg, so m<J = 120 deg.

Angles G and J from a linear pair, so they are supplementary, and the sum of their measures is 180 deg.

m<G = 180 - 120 = 60
