F(x) = x^2 - 18x + 86 Find the vertex (show steps)

Mathematics

Answer:

(9, 5)

Step-by-step explanation:

First, we can use the axis of symmetry formula to find the x value of the vertex.

This formula is: -b/2a

Plug in the b and a values:

-b/2a

-(-18) / 2(1)

18/2

= 9

Then, plug in 9 as x into the equation, and solve for y:

f(x) = x² - 18x + 86

f(9) = 9² - 18(9) + 86

f(9) = 81 - 162 + 86

f(9) = 5

y = 5

So, the vertex is at (9, 5)

Solve the equation. If necessary, round your answer to the nearest tenth.
andrew-mc [135]
3x^2 = 147
divide both sides by 3
x^2 = 49
x^2 -49 = 0
(x-7)(x+7) =0
so,, x = 7 , -7
the answer is B

Given: Q=7m + 3n, R= 11 - 2m, S= n + 5, and T= -m - 3n + 8 <br><br><br> simplify R - [S + T]
Soloha48 [4]
R = 11-2m
S = n+5
T = -m-3n+8
---------------------------
Add up S and T to get...
S+T = (n+5)+(-m-3n+8)
S+T = n+5-m-3n+8
S+T = -m+(n-3n)+(5+8)
S+T = -m+(1n-3n)+(5+8)
S+T = -m+(-2n)+(13)
S+T = -m-2n+13
---------------------------
Subtract that result from R
R - [S + T]
11-2m - [-m-2n+13]
11-2m +m+2n-13
(-2m+m) + (2n) + (11-13)
(-2m+1m) + (2n) + (11-13)
(-1m) + (2n) + (-2)
-m + 2n - 2
---------------------------
---------------------------
The final answer is -m + 2n - 2
