f(x) = (x + 1)(x - 5). What is the vertex?
(1,5)
(5.1)
(2.-9)
(-9,2)​

Answers

Answer 1

Answer:

(2, -9)

Step-by-step explanation:

f(x) = (x + 1)(x - 5)

[tex] =f(x) = {x}^{2} - 5x + x - 5[/tex]

[tex] = f(x) = {x}^{2} - 4x - 5[/tex]

[tex] = f(x) = {1x}^{2} - 4x - 5[/tex]

[tex] = f(x) = {1x}^{2} + ( - 4x) - 5[/tex]

= a = 1, b = -4

[tex] = x = \frac{ - 4}{2 \times 1} [/tex]

[tex] = x = - \frac{ - 4}{2} [/tex]

[tex] = x - ( - 2)[/tex]

[tex] = x = 2[/tex]

= f(x) = (x + 1) x (x - 5); x = 2

= f(2) = -9

= (2, -9)

Angle JID is opposite to Angle AJF(angle x)

Opposite angles are always equal

Angle JID=Angle AJF(x)

after 4 seconds


after 5 seconds


after 6 seconds

Best explanation gets Brainliest!!

Answers

Answer:

After 5 seconds

Step-by-step explanation:

One is given the following expression to model to the flight path of a ball:

[tex]h=-16t^2+80t[/tex]

In this problem, one is asked to find the time at which the ball lands on the ground. The easiest way to do so is to factor the expression. Take out factors that both terms have in common. The one will set the equation equal to zero, as this is the height at which one wants to find the time for. Finally, use the zero product property to solve. The zero product property states that any number times zero equals zero. Apply these ideas to the given function:

[tex]h=-16t^2+80t[/tex]

Factor the expression; both terms have a common factor of (-16t):

[tex]h=-16t^2+80t[/tex]

[tex]h=-16t(t-5)[/tex]

Set the equation equal to zero to solve for when the ball has a height of zero or rather lands on the ground:

[tex]h=-16t(t-5)[/tex]

[tex]0=-16t(t-5)[/tex]

Now use the zero product property, this states that any number times zero equals zero. Set each of the factors equal to zero, and solve to find the value of (t) for which the factor will equal zero:

[tex]0=-16t(t-5)[/tex]

[tex]0=-16t[/tex]                          [tex]t - 5 =0[/tex]

Solve for the value (t) using inverse operations,

[tex]0=-16t[/tex]                            [tex]t - 5 =0[/tex]

(divide by (-16)                   (add (5))

[tex]0=t[/tex]                                     [tex]t=5[/tex]

As one can see, the ball started on the ground, therefore at (0) seconds, its height was (0). Then, after (5) seconds the ball landed on the ground, therefore, after (5) seconds its height was again (0).

Find the largest prime factor of 18! + 19! + 20!

Answers

18! is common to each term in the sum:

18! + 19! + 20! = 18! (1 + 19 + 19×20) = 18!×400

The largest prime factor of 18! is of course 17.

Meanwhile,

400 = 16×25 = 2⁴×5²

so the largest prime factor of 18! + 19! + 20! is 17.

Find the degree measure of each angle in the triangle.

Answers

Step-by-step explanation:

In isocseles triangle, base angles are equal :

base angles are angle N and angle P:

angle N=angle P

3x+17=4x+2

4x-3x=17-2

x=15

For angle N:

subtitute x in angle N

=3(15)+17

=45+17

=62

For angle P:

subtitute x in angle P:

=4(15)+2

=60+2

=62

For angle O:

sum of all angles in a triangle is 180.

angle N +angle P+angle O=180

62+62+angle O=180

angle O=180-62-62

angle O=56

x = 10

Answer:

[tex](4x + 8) = (2x + 28) \\ \\ 4x + 8 = 2x + 28 \\ \\ 4x - 2x = 28 - 8 \\ \\ 2x = 20 \\ \\ x = \frac{20}{2} \\ \\ x = 10[/tex]

Hey there! I'm happy to help!

A translation is just when they are staying the same. You just move the figure along but it doesn't switch the way it is facing.

A reflection is when it is like going over a mirror. It's kind of like it rolls over. So if you are facing left on the ground and you roll over then you are facing the right. That's basically what a reflection is.

A rotation is pretty self explanatory, it's when you twist it sideways, upside down, etc. A rotation can also end up in the same position as a reflection. For example if you diagonally reflect something it is the same as a 180 degree rotation, and that might be what is stressing you out.

With your answers, I'm assuming each number has all three possible answers, so if one seems to have both, just see which answer you haven't used yet.

1) Rotation, Translation Reflection

2) Rotation, Reflection, Translation

3) Translation, Rotation, Reflection

4) Rotation, Reflection, Translation

how do you solve this problem

Answers

Answer:

(-6,1)

Step-by-step explanation:

-x + y = 7 [Equation (1)]

2x + 5y = -7 [Equation (2)]

Multiplying equation (1) by 5, to make the coefficients of y equal in both equations.

5(-x + y) = 5(7)

=> -5x + 5y = 35 [Equation (3)]

Subtracting equation (3) from equation (2).

(2x + 5y) - (-5x + 5y) = -7 - 35

=> 2x + 5y + 5x - 5y = -7 - 35

=> 7x = -42

=> x = -42/7

=> x = -6

Putting the value of x in equation (1).

-(-6) + y = 7

=> 6 + y = 7

=> y = 7 - 6

=> y = 1

So, x = -6 and y = 1.
