What equation could generate the curve in the graph below

Marianna [84]

Answer:

Step-by-step explanation:

We know the y intercept is positive so that eliminates choice D.

y = 3x^2 -2x+1

This does not intercept the x axis

y = 3x^2 -6x+3

= 3(x^2 -2x+1)

3(x-1)^2

This intercepts the x axis at 1

This is not the equation for the graph

y = 3x^2 -7x+1

Let x = 1

y = 3-7+1

= -3

This will cross the x axis, so this cannot be the graph

What is the simplified form of (81x^4y^9)^1/2

aniked [119]

Answer:

C 9 *x^2 y^ 4 y^ 1/2

Step-by-step explanation:

(81x^4y^9)^1/2

We know that (ab)^1/2 = a^1/2 *b^1/2

(81) ^1/2 * (x^4) ^1/2 * (y^9)^1/2

We know that a^b^c = a^ (b*c)

(81) ^1/2 * (x^(4*1/2) * (y^(9*1/2)

9 *x^2 y^ 9/2

We know that y^9/2 = y^4 y^1/2

9 *x^2 y^ 4 y^ 1/2

(-5a+6)(-4a+3) <br><br> Cannot be a fraction

torisob [31]

Hey there!

To solve this problem, we will take a look at the FOIL Method.

FOIL is a simple acronym that can be used to multiply binomials. It stands for:

F - Front

O - Outer

I - Inner

L - Last

See the image below for an example of how to use this in the given situation.

<h3>Apply</h3>

Front: <em>Multiply the two terms out in the front.</em>

$(-5a)(-4a) = 20a^2$

Outer: <em>Multiply the two terms on the outsides.</em>

$(-5a)(3)=-15a$

Inner: <em>Multiply the two terms on the insides.</em>

$(6)(-4a)=-24a$

Last: <em>Multiply the two terms in the back.</em>

$(6)(3)=18$

Now, we add all of our answers from above:

$20a^2-15a-24a+18$

<h3>Simplify</h3>

Simplify by combining like terms:

$20a^2-39a+18$

There's our answer!
