Answer:

f(x) = (x - 2)(x + 2)

Step-by-step explanation:

When you expand out the expression, you should get f(x) = x² - 4, where only vertical movement is present. Therefore, the vertex is on the y-int at (0, -4) and your answer is the 3rd choice.

3x+4y+6z=15 Solve for x.

Answer:

Step-by-step explanation:

<h3>Question:-</h3>

To solve for x

<h3>Equation:-</h3>

3x + 4y + 6z = 15

<h3>Solution:-</h3>

=> 3x + 4y + 6z = 15

[On subtracting both sides with 4y]

=> 3x + 4y + 6z - 4y = 15 - 4y

[On Simplification]

=> 3x + 6z = 15 - 4y

[On subtracting both sides with 6z]

=> 3x + 6z - 6z = 15 - 4y - 6z

[On Simplification]

=> 3x = 15 - 4y - 6z

[On dividing both sides with 3]

$= > \frac{3x}{3} = \frac{15 - 4y - 6z}{3}$

[On Simplification]

$= > x = 5 - \frac{4}{3} y - 2z \: (ans)$

Look at the table of values below. x y 1 3 2 7 3 11 Which equation is represented by the table? A. y = 2x + 1 B. y = 3x + 2 C. y

lesya [120]

Answer:

C. y = 4x − 1

Step-by-step explanation:

x y

We can find the slope

m = (y2-y1)/(x2-x1)

= (11-7)/(3-2)

= 4/1

The slope is 4

The only equation with a slope of 4 is

y = 4x − 1

Check a point

(1,3)

y = (4)*1 -1

y=3

Checks so this works

You roll a six-sided die one time. After that, you spin a spinner that is equally divided into 6 parts. 2 parts are red, 1 part

Tanzania [10]

Answer:

Step-by-step explanation:

This is a probability problem, so let us treat it as such.

the sample space for the die is =(1,2,3,4,5,6)

the sample size is =6

For the spinner the sample space is

red=2

pink=1

white=3

the sample size for the spinner is =6

The probability of rolling a number greater than 1 and then the spinner stopping at a pink section

=Pr(no>1)*Pr(spinner=pink)

no>1= 2,3,4,5,6

no>1=5

pink=1

hence

=5/6*1/6

=5/36

<h2>The probability is 5/36</h2>
