f(x)=-x²-2x-8 determine the vertex
Answer:
vertex = (- 1, - 7 )
Step-by-step explanation:
Given a parabola in standard form, f(x) = ax² + bx + c (a ≠ 0 )
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
f(x) = - x² - 2x - 8 ← is in standard form
with a = - 1 and b = - 2, then
[tex]x_{vertex}[/tex] = - [tex]\frac{-2}{-2}[/tex] = - 1
Substitute x = - 1 into f(x) for corresponding y- coordinate
f(- 1) = - (- 1)² - 2(- 1) - 8 = - 1 + 2 - 8 = - 7
vertex = (- 1, - 7 )
Natasha and Richard win some money and share it in the ratio 5:2. Natasha gets £75. How much did Richard get?
Answer:

This is what I got. I don't see anything in the equation that has "i" in it.
If it is supposed to be (-7-4i)(8-6) foil the problem.
-56+42-32i+24i combine like terms
the answer is -14-8i

x2 - 2x + = 4(x2-2x +1)-3
Answer:
-3x² +6x -1 = 0
Step-by-step explanation:
x2 - 2x + = 4(x2-2x +1)-3
x² - 2x = 4x²-8x +4 - 3
x²-4x²-2x+8x = 4-3
-3x² +6x = 1
-3x² +6x -1 = 0
There are 33.8 fluid ounces in a liter. There are 128 fluid ounces in a gallon. About how many liters are in a gallon? 2 3 4 5 Is your estimate larger or smaller than the actual number of liters in a gallon? Explain how you know. HTML EditorKeyboard Shortcuts

Please helppp I’m struggling give your awnser in simplest form.
Answer:
[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
To find the slope, you need to find any 2 points on the line.
In this case, there is a point at (0, 0), and a point at (4, 3).
Formula for slope: [tex]m = \frac{rise}{run}[/tex]
The rise is the change in the y axis from point 1, in this case (0, 0), to point 2, in this case (4, 3). The run is the change in the x axis from point 1 to point 2.
You can subtract the point 1 values from point 2 to get the rise and run:
[tex]m = \frac{3 - 0}{4 - 0} = \frac{3}{4}[/tex]
y=2x-6
-3. Y
0. Y
3. Y
6. Y
Solve for Y
Answer:
y=0
Step-by-step explanation:
y=2x-6 (add 6 to both sides)
6=2x (divide 2 to both sides)
3=x
-----------------------------------------------------------------------------------------------------------------
y=2(3)-6
y=6-6
y=0

(ii) = -9
E

Answer:
The value of k=13
Step-by-step explanation:
Given the equation
[tex]2\left(k\:-3\right)\:=\:k\:+7[/tex]
[tex]2k-6=k+7[/tex]
Add 6 to both sides
[tex]2k-6+6=k+7+6[/tex]
[tex]2k=k+13[/tex]
subtract k from both sides
[tex]2k-k=k+13-k[/tex]
[tex]k=13[/tex]
Therefore, the value of k=13
