Answer:
slope intercept form.
Step-by-step explanation:
heres the slope intercept form: y=mx+b.
this equation is what you will use to plot lines on graphs, points etc.
the letter b represents the y-intercept, where the line crosses a number on the y intercept on the graph. for example, an initial payment of 30 dollars.
the mx represents slope, or rate of change. for example, paying 5 dollars an hour.
you wouldn't plug a number to the x, but instead the m, because you'd multiply the m with the x.
Based on your question, I think you are asking what slope is. Slope is the rate of change.
Hope this helps!

Aaron can paint a door in 6 h, and Ana can do the same job in 3 h. Working together, how many hours will it take them to paint a door?
h
Answer:
4.5
Step-by-step explanation:
that is
their rates =1/6, 1/3 respectively
total =1/2
if 1/2=9
1= 9/2
= 4.5
We want to find the rate at which Aaron and Ana work together, we will find that when working together they can paint 1 door in 2 hours.
Working with rates:
We know that Aaron can paint a door in 6 hours and Ana can paint the same door in 3 hours. The rates are just defined as the number of doors painted over time, so we get:
Aaron's rate = (1 door/ 6h)Ana's rate = (1 door/ 3h)When they work together the rates just add up, so we get:
R = (1 door/ 6h) + (1 door/ 3h) = (1 door/ 6h) + (2 door/ 6h)
= (3 doors/6 hours) = (1 door/ 2 hours)
This means that, working together, they can paint 1 door in 2 hours.

Understanding Functional Relationships
Which statements are true of functions? Check all that apply.
O AIl functions have a dependent variable.
Al functions have an independent variable.
0 The range ofa function includes its domain
DA vertical line is an example ofa functional relationship.
O A horizontal line is an example of a functional relationship.
O Each output value of a function can correspond to only one input value.
Answer:
A horizontal line is an example of a functional relationship.
All functions have an independent variable.
All functions have a dependent variable (At least).
Step-by-step explanation:
By description, a relation is a purpose if each input condition has one and only one output value.
A function has at least a secondary variable and an autonomous variable. For instance, given a function:
Y=X
The secondary variable is "y" and the autonomous variable is "x".
The Field of the role is the collection of potential input values and the Range is the collection of potential output values,
Vertical lines have an irregular slope. Since the value of "x" never varies, an upward line is not an illustration of a functional relationship.
In the matter of Horizontal lines, for any x-value, you get the equivalent y-value. These are described as Constant functions.

A plane parallel to the base of a pyramid divides the pyramid into two pieces. Find the ratio of the volume of the top part of the whole pyramid to the volume of the bottom part.
Answer:
Step-by-step explanation:
There are several ambiguities in your question upon which I feel disinclined to speculate. It cries out for an explanatory diagram:
For example (i.e. including but not only!):
1. What is the essential distinction between a plane and a regular pyramid?
2. Does each of the two solids have all of its own edges equal, independently of the other solid? Or are the corresponding edges of the two solids equal? Or are all edges of both solids equal?
A small aircraft starts its descent from an altitude of h = 1.4 miles, 4 miles west of the runway
a. Find the cubic f(x)=ax3+bx2+cx+d on the interval [−4,0] that describes a smooth glide path for the landing.
b. The function in part (a) models the glide path of the plane. When would the plane be descending at the greatest rate?
Answer:
Step-by-step explanation:
From the question we are told that
Altitude of Height 1.4miles
4miles west
a) From the question
[tex]f(x)=ax3+bx2+cx+d[/tex] on interval (-4,0)
The descent can be expressed in [tex]\triangle _x =-4,0[/tex]
therefore initial points is (-4 , 1.4).
final co-ordinate is given by (0,0) as its landing
Mathematically solving in above cubic equation
[tex]0 = 0 + 0 + 0 + d \\[/tex]
[tex]d = 0[/tex]
[tex]1.4 = -64a + 16b -4c + d[/tex]
[tex]1 = -45.7a + 11.4b-2.9c+d[/tex]
Generally in this case Slope of tangent at point of descent is zero.assuming flight was initially straight before descent
[tex]f'(x) = 3ax^2 + 2bx+c[/tex]
[tex]f'(-4) = 48a -8b + c = 0[/tex]
[tex]f'(0) = c = 0[/tex]
Mathematically solving above equations we have
[tex]a = \frac{1}{40} \ and \ b = \frac{3}{20}[/tex]
Therefore having found a and b the Cubic equation is given as
[tex]f(x) = \frac{1}{40}x^3 + \frac{3}{20}x^2[/tex]
b)descent at its greatest rate
[tex]f(x)=\frac{1.4}{40} x^3 + \frac{129}{20} x^2[/tex]
[tex]f(x)=\frac{1.4}{40} x^3 + \frac{129}{20} x^2[/tex]

9. Gross Margin equals $50,000, operating expenses equals $23,000, income
taxes equals $5,400 and sales is $110,000. What is the company's net income?
Answer:
$21600
Step-by-step explanation:
Net income is calculated by deducting all company expenses from its total revenue. Net income is given by the formula:
Net income = Revenue - cost of goods sold - operating expenses - tax.
But Gross margin = gross profit = Revenue - cost of goods sold. Hence:
Net income = Gross margin - operating expenses - tax.
Substituting gives:
Net income = $50000 - $23000 - $5400
Net income = $21600
If f(x) = 3x2, what is the x-coordinate of the point of intersection of the graphs of y = f(x) and y = f(x − 4)?
Step-by-step explanation:
When f(x) = f(x - 4), 3x² = 3(x - 4)².
=> x² = (x - 4)², x = -(x - 4), 2x = 4, x = 2.
The x-value is 2.

Rewrite 45 + 60 using the distributive property.
Answer: 15(3+4)
Step-by-step explanation:
First, we want to find the GCF of these numbers
The greatest number they can both be divided by is 15
All of the possible factors are 1, 3, 5, 9, 15, and 15 is the highest
So 15 is the GCF
We then divide these numbers to get the equation
45/15=3
60/15=4
So the new equation would be (3+4)
We then add the GCF outside the parenthesis so you can distribute it in order to get the original numbers
So the distributive equation would be 15(3+4)
Answer 15(3+4)

In a G.P the difference between the 1st and 5th term is 150, and the difference between the
2nd and the 4th terms is 48. Find the sum of the first five terms.
Answer:
Either [tex]\displaystyle \frac{-1522}{\sqrt{41}}[/tex] (approximately [tex]-238[/tex]) or [tex]\displaystyle \frac{1522}{\sqrt{41}}[/tex] (approximately [tex]238[/tex].)
Step-by-step explanation:
Let [tex]a[/tex] denote the first term of this geometric series, and let [tex]r[/tex] denote the common ratio of this geometric series.
The first five terms of this series would be:
[tex]a[/tex], [tex]a\cdot r[/tex],[tex]a \cdot r^2[/tex],[tex]a \cdot r^3[/tex], [tex]a \cdot r^4[/tex].First equation:
[tex]a\, r^4 - a = 150[/tex].
Second equation:
[tex]a\, r^3 - a\, r = 48[/tex].
Rewrite and simplify the first equation.
[tex]\begin{aligned}& a\, r^4 - a \\ &= a\, \left(r^4 - 1\right)\\ &= a\, \left(r^2 - 1\right) \, \left(r^2 + 1\right) \end{aligned}[/tex].
Therefore, the first equation becomes:
[tex]a\, \left(r^2 - 1\right) \, \left(r^2 + 1\right) = 150[/tex]..
Similarly, rewrite and simplify the second equation:
[tex]\begin{aligned}&a\, r^3 - a\, r\\ &= a\, \left( r^3 - r\right) \\ &= a\, r\, \left(r^2 - 1\right) \end{aligned}[/tex].
Therefore, the second equation becomes:
[tex]a\, r\, \left(r^2 - 1\right) = 48[/tex].
Take the quotient between these two equations:
[tex]\begin{aligned}\frac{a\, \left(r^2 - 1\right) \, \left(r^2 + 1\right)}{a\cdot r\, \left(r^2 - 1\right)} = \frac{150}{48}\end{aligned}[/tex].
Simplify and solve for [tex]r[/tex]:
[tex]\displaystyle \frac{r^2+ 1}{r} = \frac{25}{8}[/tex].
[tex]8\, r^2 - 25\, r + 8 = 0[/tex].
Either [tex]\displaystyle r = \frac{25 - 3\, \sqrt{41}}{16}[/tex] or [tex]\displaystyle r = \frac{25 + 3\, \sqrt{41}}{16}[/tex].
Assume that [tex]\displaystyle r = \frac{25 - 3\, \sqrt{41}}{16}[/tex]. Substitute back to either of the two original equations to show that [tex]\displaystyle a = -\frac{497\, \sqrt{41}}{41} - 75[/tex].
Calculate the sum of the first five terms:
[tex]\begin{aligned} &a + a\cdot r + a\cdot r^2 + a\cdot r^3 + a \cdot r^4\\ &= -\frac{1522\sqrt{41}}{41} \approx -238\end{aligned}[/tex].
Similarly, assume that [tex]\displaystyle r = \frac{25 + 3\, \sqrt{41}}{16}[/tex]. Substitute back to either of the two original equations to show that [tex]\displaystyle a = \frac{497\, \sqrt{41}}{41} - 75[/tex].
Calculate the sum of the first five terms:
[tex]\begin{aligned} &a + a\cdot r + a\cdot r^2 + a\cdot r^3 + a \cdot r^4\\ &= \frac{1522\sqrt{41}}{41} \approx 238\end{aligned}[/tex].
