Answer:
2
Step-by-step explanation:
First, take the derivative of 2x:
f(x)=2x becomes f'(x)=2
now since this is a constant regardless of what x you "plug" in you will have 2.
Which is the graph of the function f(x) = -x
what is 2+2-3?

Solve the equation for x
√x+4-7=1
Options:
x=4
x=12
x=60
x=68
Answer:
i honestly dont know its tooooo hard
Step-by-step explanation:
Answer:
x=4
Step-by-step explanation:
To remove the radical on the left side of the equation, square both sides of the equation.
√x+4−72=12x+4-72=12
Simplify each side of the equation.
x−3=1x-3=1
Move all terms not containing xx to the right side of the equation.
x=4

Write the equation for Axis of Symmetry (AOS) for: y = 2(x – 3)² + 4
Answer:
X=3
Step-by-step explanation:
The axis of symmetry is 3 because we already know the value of h and k from vertex equation also known as y=a(x-h)²+k when a≠0
If you want to know the equation of symmetry, it is -b/2a when a ≠ 0
[tex]\frac{-b}{2a}[/tex] But if we want to use this formula, we have to convert the vertex form into standard form.
[tex]y=2(x^2-6x+9)+4\\y=2(x^2-6x+9)+13\\y=2x^2-12x+9+13\\y=2x^2-12x+22[/tex]
Therefore, the standard form of y=2(x-3)²+4 is 2x²-6x+22
We can use the axis of symmetry formula or -b/2a
From the equation, b is -12 and a is 2. Substitute both b and a in the -b/2a
Thus, -(-12)/2(2) = 12/4 = 3 #
Therefore, the axis of symmetry is 3. Using the Axis of Symmetry Formula, -b/2a
Simplify completely

Write the equation 3x + 2y = 18 in slope-intercept form. What are the slope and the y-intercept?
Answer:
Step-by-step explanation:
Slope intercept form: y=mx+b
3x+2y=18
3x-18=-2y
divide by -2 both sides
y=-3/2x + 9
slope: -3/2
y-intercept: 9
Answer: y = -3/2x + 9
Steps: 3x + 2y = 18
convert to slope intercept form: y = -3/2x + 9

first one is 4x
Step-by-step explanation:
Let me help. try doing what is in parenthesis first and then do the rest. for example, if u look at number 2, you have 8x - 6x + 4x. you have to solve whichever comes first. in this case, its 8x - 6x, which equals 2x. next you have +4x. 2x + 4x= 6x. hope this helped :)

f(3) is ___
Answer:
f(3) is - 1
Step-by-step explanation:
f(3) means the function value when x = 3
3 is in the domain, the function value is in the range.
Thus when x = - 3 → y = - 1
f(3) is - 1
The value of given mapping diagram for function f(3) is - 1
What is Mathematical function ?
Mathematical function is the representation of relation between independent variables and dependent variables.
Here is given mapping diagram f(3) means the function value x = 3
3 is in the domain which is independent of range as shown in diagram.
Thus when x = 3 the range is approaching towards y = - 1
therefore, f(3) equals - 1

the area of a rectangular window is 6216 cm^2. if the length of the window is 84 cm, what is it's width?
Answer:
The answer is 74 cmStep-by-step explanation:
The area of a rectangle = length × width
Since we are finding the width
We have
[tex]width = \frac{area}{length} \\ [/tex]
From the question
area = 6216 cm²
length = 84 cm
The width is
[tex]width = \frac{6216}{84} \\ [/tex]
We have the final answer as
74 cmHope this helps you
