Evaluate -2x^2-4x+3 when x=-2

Mathematics

Misha Larkins [42]2 years ago
8 0

Answer:

  3

Step-by-step explanation:

A polynomial is sometimes easier to evaluate if it is first written in Horner form:

  -2x^2 -4x +3 = (-2x -4)x +3

For x = -2, this is ...

  (-2(-2) -4)(-2) +3 = 0(-2) +3 = 3

The value is 3 when x = -2.

Answer:

y - 4x = 1

Step-by-step explanation:

Given

(x_1,y_1) = (1,5)

(x_2,y_2) = (3,13)

Required

The equation of the line

Back up:

First, calculate the slope(m)

m = \frac{y_2 -y_1}{x_2 - x_1}

m = \frac{13-5}{3-1}

m = \frac{8}{2}

m = 4

Calculate the area using:

y - y_1 = m(x - x_1)

y- 5 = 4(x - 1)

y- 5 = 4x - 4

Collect Like Terms

y - 4x = 5 - 4

y - 4x = 1
