F(x)=-x^2+6x+14 vertex
sasho [114]

Answer:

Vertex: (3, 23)

Step-by-step explanation:

a = -1   b = 6   c = 14

x vertex = \frac{-b}{2a}

\frac{-6}{-2}=3

f(x)-x^{2} +6x+14\\f(3) = -(3)^{2}+6(3) + 14 \\f(3)=-9+18+14\\f(3)=23

What is the length of the line segment with endpoints (11,−4) and (−12,−4) ?
bija089 [108]

Answer:

Length of the line segment with endpoints (11,−4) and (−12,−4)  is 23 units

Step-by-step explanation:

Given:

Endpoints are (11,−4) and (−12,−4)

To Find:

The length of the line = ?

Solution:

The length of the line can be found by using the distance formula

\sqrt{(x_2-x_1)^2 +(y_2 - y_1)^2

Here

x_1= 11

x_2= -12

y_1= -4

y_2= -4

Substituting the values

Length of the line

=>\sqrt{((-12)- 11)^2 +((-4) - (-4))^2

=>\sqrt{(-12- 11)^2 +(-4+4)^2

=>\sqrt{(-23)^2 +(0)^2

=>\sqrt{529}

=>23

Simplify your answer
katrin [286]

Answer: x=4\\y=3

Step-by-step explanation:

y=4x-13\\2x+3y=17

Since our ''y'' is already isolated, you can simply plug ''y'' information into the second equation.

2x+3y=17\\2x+3(4x-13)=17\\2x+12x-39=17\\14x=17+39\\14x=56\\x=\frac{56}{14} \\x=4

Now we can use the first equation and replace ''x'' to find ''y''

y=4x-13\\y=4(4)-13\\y=16-13\\y=3

To prove that your values are correct, take any of the equations and replace their values.

y=4x-13\\3=4(4)-13\\3=16-13\\3=3
