Complete the statements below that show y = x2 + 2x - 1 being converted to vertex form.
Form a perfect-square trinomial.
y = x2 + 2x +
− 1−
We want to complete the steps to convert the given quadratic equation into vertex form.
Eventually we will get:
y = (x + 1)^2 - 2
Vertex form of a quadratic equation.
For a quadratic equation with the vertex (h, k), the vertex form is:
y = a*(x - h)^2 + k
Here we start with:
y = x^2 + 2x - 1
1) First, we complete the perfect-square trinomial, we need to add and subtract 1 to get that:
y = x^2 + 2x - 1 + 1 - 1
2) Now we rewrite the equation to be able of completing squares:
y = (x^2 + 2x + 1) - 1 - 1
y = (x^2 + 2x + 1) - 2
3) Now we complete squares
y = (x + 1)^2 - 2
And this is the equation in vertex form, where you can see that the vertex is the point (-1, - 2)

Which equation represents the vertical line passing through (7,-3)?
Answer:
x = 7
Step-by-step explanation:
The equation of a vertical line has equation of the form
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (7, - 3) with x- coordinate 7 , thus
x = 7 ← equation of vertical line

Factorise m^3+m
Factorise 25-y^2
Factorise x^2+3x-28
Answer:
1. m³ + m
= m( m² + 1) [ a² + b²]
= (a-b)² + 2ab
= m { (m –1)² + 2× m × 1 }
= m { ( m–1)² + 2m}
2. 25 – y² [ a² – b²]
= 5² – y²
= (5+y) (5–y)
3. x² + 3x –28 [ middle term factorisation]
= x² + 7x –4x –28
= x( x +7) –4 ( x + 7 )
= ( x–4) (x+7)

What is the range of y = x2 – 1, given a domain of {-2,-1,0, 1, 2}?
A. R:{-5, -2, -1,0.3)
B. R: -1
O
C. R:y > -1
OD. R:{-1,0,3}
Answer:
D
Step-by-step explanation:
Basically, what the question is asking you to do is plug in each of the domain numbers (because domain represents X) and solve for y. Btw, after plugging in each domain to separate equations, if you end up with two numbers being the exact same, you only need to put one of them, hence why there are only 3 numbers in this answer. Hope with helps, any questions just ask me.

SegmentAB≅SegmentCD. AC = 6x-12 , BC = 4, and CD = 3x-2. Find AB and CD. (Geometry Proof)
Answer/Step-by-step explanation:
Given:
AC = 6x - 12
BC = 4
CD = 3x - 2
Required:
Determine length of AB and CD.
SOLUTION:
AC - BC = AB
(6x - 12) - 4 = AB (Substitution)
6x - 12 - 4 = AB
6x - 16 = AB
Since AB ≅ CD, therefore,
AB = CD
6x - 16 = 3x - 2 (Substitution)
Combine like terms
6x - 3x = 16 - 2
3x = 14
Divide both sides by 3
x = 4.7
Find AB
6x - 16 = AB
Plug in the value of x
6(4.7) - 16 = AB
28.2 - 16 = AB
12.2 = AB
Find CD
CD = 3x - 2
Plug in the value of x
CD = 3(4.7) - 2
CD = 14.1 - 2
CD = 12.1

[tex]\frac{11}{8}[/tex]Answer:
55 in by 40 in
Step-by-step explanation:
The perimeter (P) of a rectangle is calculated as
P = 2l + 2w ( l is the length and w the width )
Here l = [tex]\frac{11}{8}[/tex] y and w = y with P = 190
2y + (2 × [tex]\frac{11}{8}[/tex] y ) = 190
2y + [tex]\frac{11}{4}[/tex] y = 190 ( multiply through by 4 to clear the fraction )
8y + 11y = 760 , that is
19y = 760 ( divide both sides by 19 )
y = 40
Thus l = [tex]\frac{11}{8}[/tex] × 40 = 11 × 5 = 55 in and w = 40 in
