General Formulas and Concepts:
Pre-Algebra
Equality PropertiesAlgebra
Combining like termsStandard Form: ax² + bx + c = 0Step-by-step explanation:
Step 1: Define
f(x) = 3x² - 2
g(x) = 2x + 4
(f - g)(x) is f(x) - g(x)
Step 2: Find
Substitute: (f - g)(x) = 3x² - 2 - (2x + 4)Distribute -1: (f - g)(x) = 3x² - 2 - 2x - 4Combine like terms: (f - g)(x) = 3x² - 2x - 6Solve the following linear equations
(i) 2(k − 3) = k +7
(ii) = -9

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
I need helppp please
Answer:
How pooor are you it'svery hard
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]

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 )

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
Answer:
1 gallon = 3.7869 Liter (Approx)
Step-by-step explanation:
Given:
1 liter = 33.8 ounces
1 gallon = 128 ounces
Find:
How many liters are in a gallon
Computation:
1 ounces = [ 1 / 33.8 ] liter
1 gallon = 128 ounces
1 gallon = 128 [1 / 33.8]
1 gallon = 3.7869 Liter (Approx)
