f(x+h) = (x+h)² + 3(x+h)^3
How would I distribute this?
Answer:
f(x + h) = 3x³ + x² + 9h²x + 3h³ + h² + 9hx² + 2hx
General Formulas and Concepts:
Order of Operations: BPEMDASDistributive PropertyExpand by FOIL (First Outside Inside Last)Combining like termsStep-by-step explanation:
Step 1: Define function
f(x) = x² + 3x³
f(x + h) is x = x + h
Step 2: Simplify
Substitute: f(x + h) = (x + h)² + 3(x + h)³Expand by FOILing: f(x + h) = (x² + 2hx + h²) + 3(x + h)³Rewrite: f(x + h) = (x² + 2hx + h²) + 3(x + h)²(x + h)Expand by FOILing: f(x + h) = (x²+2hx+h²) + 3(x² + 2hx + h²)(x+h)Distribute/Expand: f(x + h) = (x²+2hx+h²) + 3(x³+3hx²+3h²x+h³)Distribute 3: f(x + h) = (x²+2hx+h²)+(3x³+9hx²+9h²x+3h³)Combine like terms: f(x + h) = 3x³+x²+9h²x+3h³+h²+9hx²+2hxUse inverse operations to solve: x + 3.2 = 7
Answer:
x=3.8
Step-by-step explanation:
You would use the inverse operation by subtracting 3.2 from both sides of the equation, leaving you with x=3.8
Which of these tables represent a nonlinear function?
Answer:
(3)
Step-by-step explanation:
Analise the slope m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
(1). (19-20)/(18-17) = - 1 ; (18-19)/(19-18) = - 1 ; (17-18)/(20-19) = - 1 ⇒ table represents a linear function.
(2). (-17+16)/(18-17) = - 1 ; (-18+17)/(19-18) = - 1 ⇒ table represents a linear function.
(3). (17-16)/(18-17) = 1 ; (19-17)/(19-18) = 2 ⇒ table represents a nonlinear function.

Determine if the lines are parallel, perpendicular, or neither.
3y = -2x + 18 and 6x + 9y = 18
Parallel
Perpendicular
Neither
Answer:
parallel
Step-by-step explanation:
1st step get the equations in y=mx+b
3y = -2x + 18
(÷ each side by 3)
y = -2/3x + 6
6x + 9y = 18
(subract 6x to get it to the other side)
9y = -6x + 18
(÷ both sides by 9)
y = -6/9x + 2
(simplify -6/9)
y = -2/3x +2
2nd step look at the equations
y = -2/3x + 6 and y = -2/3x +2
The lines are at different places and will never touch, having same slope theres never a possibility they would look something like this \\

Audrey's bank account is currently at $75 a fee of 12.50 is deducted each month from Audreys she must maintain a balance greater than zero dollars how many months will Audrey's account stay above zero dollars
Answer:
5 months
Step-by-step explanation:
Current balance = $75
Monthly deductions = $12.50
75 - 12.5h
Where ,
h = number of months for deduction
she must maintain a balance greater than zero dollars
how many months will Audrey's account stay above zero dollars
0 > 75 - 12.5h
0 - 75 > -12.5h
-75 > - 12.5h
h < -75 / 12.5h
h < 6 months
h < 6 months means h must be less than 6 months which is 5 months
Audrey's account will stay above zero dollars for 5 months and will equal zero dollars in the 6th month
The larger of two numbers is sixteen less than twice the smaller number. If the sum of the numbers is 44, find the two numbers. Write your answer as two numbers separated by a coma.
Answer:
20, 24
Step-by-step explanation:
smaller: x
larger: 2x - 16
x + 2x - 16 = 44
3x -16 = 44
3x = 60
x = 20
smaller: x = 20
larger: 2x - 16 = 2(20) - 16 = 24

x intercept is 1 and y intercept is 2
Step-by-step explanation:
Answer:
x-intercept = (0, 2) or 2
y-intercept = (1, 0) or 1
Step-by-step explanation:
The x-intercept is where the line passes the x-axis, and the y-intercept is where the line passes the y-axis.
The line passes through the y-axis at (0, 2)
The line passes through the x-axis at (1, 0)

A store is marking down the price of a television 25 percent from the original price of $250. Which expression can be used to find the marked down price?
250 dollars minus (0.25) (250)
250 dollars + (0.25) (250)
250 dollars minus (25) (250)
250 dollars + (25) (250)
Answer:
A
Step-by-step explanation:
You're looking for the marked down price, which is less than the original 250, thus B and D is instantly knocked out. 25% as a decimal is expressed as .25, meaning that the only plausible answer in this scenario is A
Answer:
A. 250 dollars minus (0.25) (250)

You run 7 1/2 miles as a part of an exercise routine. You run 1/2 of that distance on a hill. You run down a slope for the last 1/3 of the hill. On how many miles of your run do you run down the slope? Write your answer as a fraction or mixed number in simplest form.
Answer:
1 1/4 milesStep-by-step explanation:
Amount of miles ran as part of an exercise routine = 7 1/2 miles = 15/2 miles
If you run 1/2 of that distance on a hill, the distance ran on the hill will be;
= 1/2 of 15/2
= 1/2 * 15/2
= 15/4 miles
If You run down a slope for the last 1/3 of the hill, the number of miles that you run down the hill will be;
1/3 of 15/4
= 1/3 * 15/4
= 15/12
= (3*5)/(3*4)
= 5/4
Write 5/4 as a mixed fraction
5/4 = 1 1/4 miles
Therefore you ran 1 1/4 miles down the slope

[tex]f(x) = {x}^{2} + 5[/tex]
[tex]y = {x}^{2} + 5[/tex]
[tex] {x}^{2} + 5 = y[/tex]
Subtract sides 5
[tex] {x}^{2} + 5 - 5 = y - 5[/tex]
[tex] {x}^{2} = y - 5[/tex]
[tex]x = ± \sqrt{y - 5} [/tex]

Because x is a positive number but -√y-5 is a negative number thus it's unacceptable.

What is the argument of z = 1/16 - square root of 3/16 i?
Answer:
A
Step-by-step explanation:
Edg2020
The value of the argument of z is -π/3.
What is the argument of z?The angle that the line from Ф, z to the origin creates with the positive direction of the real axis is known as the argument of z is Ф, and it is variously represented by the symbols arg ( z ), (z) or Ф. Because it is an argument of z is Ф, then 2 nπ + Ф is likewise a valid argument, the argument of z can take on any number of conceivable values.
We define a singular value known as the major argument of z to be more precise.
Given z = 1/16 - √3/16i
equation of z is x + iy
here x = 1/16 and y = -√3/16
to find the angle,
tanФ = y/x
tanФ = (-√3/16)/(1/16)
tanФ = -√3
Ф = tan⁻¹(-√3)
Ф = -π/3
Hence arguement of z is -π/3.
