Write Y=3x^2+6x+8 In Vertex form
vampirchik [111]
ANSWER

The vertex form is

y = 3 {(x + 1)}^{2} + 5

EXPLANATION

We want to write

y = 3 {x}^{2}  + 6x + 8
in the vertex form which of the form


y = a {(x - h)}^{2}  + k

We achieve this BG completing the square.

We proceed as follows,

y = 3( {x}^{2}  + 2x) + 8


We add and subtract half the coefficient of x multiplied by a factor of 3 which is
3( \frac{1}{2}  \times 2)^{2}  = 3( {1)}^{2}


This gives us,


y = 3( {x}^{2}  + 2x) +  3 {(1)}^{2} -3 {(1)}^{2} + 8

We still factor 3 out of the first two terms to get,

y = 3( {x}^{2}  + 2x +  {1}^{2} ) -3 {(1)}^{2} + 8

We now got a perfect square, which factors to,


y = 3 {(x + 1)}^{2} + 5
The equation is now in the vertex form.

Describe a real-life situation that can be modeled by 7x=1.75
Deffense [45]

7 apples cost $1.75, hence The cost of each apple is $0.25.

<h3>Equation</h3>

An equation is an expression that is used to show the relationship between two or more variables and numbers.

Let x represent the cost of each apple. Let us assume that 7 apples cost $1.75, the equation can be represented by:

  • 7x = 1.75
  • x = $0.25

The cost of each apple is $0.25.

What is an equation of the line that is parallel to y=2x−10 and that passes through the point (−2,11) ?
ladessa [460]

If its parallel to y=2x-10, which has a slope of 2, the slope of the new line is 2 (the same slope).

use point slope form:

y - y1 = M (x - x1) where M is slope

y - 11 = 2( x -(-2))

y - 11 = 2( x + 2)

y - 11 = 2( x + 2)

y -11 = 2x + 4

y = 2x +4 +11

y = 2x + 14 has a parallel slope and goes through (-2, 11)
