You are given the vertex first so then you plug in the vertex in the vertex form for a quadratic equation which is y=a(x-h)^2+k. After you plug it in, you should have the equation y=a(x+2)^2-20. You are also given another point (0,-12) You then plug in the coordinates and solve for a. After you find your a you simply input the a,h and k values and leave the x and y alone.

Give me the answer please

dusya [7]

Answer:

-2

Step-by-step explanation:

The line in the graph has a slope of 1/2. Perpendicular means the opposite sign and the reciprocal, so it would be -2.

Answer:

A and C if this was ABCDE

Step-by-step explanation:

150 times 3 plus 22 would equal 450 plus 22 which is 472,

265 times three is 795 plus 22 is 817,

for the BDE, 175 times 3 is 525 plus 22 is 547, 300 times 3 is 900 plus 22 is 922, and 345 times 3 is 1035 plus 22 is 1057

Write 1 quadratic equation that forms a graph through the points (-4, 0) and (2.0) and has a maximum value at the vertex.

mel-nik [20]

P1 = (-4, 0)

P2 = (2,0)

From the information given, we can conclude that this is a vertical parabola that opens downwards.

Also we can see that the vertex is not (0,0)

Equation

(x - h)^2 = 4p(y - k)

To find the equation I need three point, to form 3 equations.

The values that I need to find are: h, k and p

Which polynomial is factored completely?

nadezda [96]

Answer:

Complete factored: (4x+4)(x+1) and 2x(x²-4)

Step-by-step explanation:

We have to check each option one by one

Option 1: $121x^2+36y^2$

It is sum of two perfect square, As we know sum of two perfect square can't be factored. It is prime equation.

False

Option 2: $(4x+4)(x+1)$

Here we have two factor (4x+4) and (x+1). In both factor degree of x is 1. It is complete factor form.

Complete factor: $4(x+1)(x+1)$

True

Option 3: $2x(x^2-4)$

Here we have two factor 4x and x²-4. For second factor it is further factor. Because it is difference of square. Factor of x²-4 = (x+2)(x-2)

Complete Factor: 2x(x+2)(x-2)[/tex]

True

Option 4: $3x^4-15n^3+12n^2$

Here variable are not same. So, it can't be factor.

False
