Answer:
x+2 = 18
x = 18-2
x=16
3(x+2) =18
3x + 6 =18
3x = 18 -6

Answer:
There is no equation that you can write for that because the slope is undefined becasue 0 is in the denominator
Step-by-step explanation:
9514 1404 393
Answer:
4x +5y = 25
Step-by-step explanation:
One way to write the equation is ...
(y2 -y1)x -(x2 -x1)y = (y2 -y1)(x1) -(x2 -x1)(y1)
(1 -5)x -(5 -0)y = (1 -5)0 -(5 -0)5
-4x -5y = -25 . . . . . has a leading minus sign, so we want to multiply by -1
4x +5y = 25 . . . . standard form equation of the line
__
Another way to write the equation is ...
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (1 -5)/(5 -0)(x -0) +5
y = -4/5x +5 . . . . slope-intercept form of the equation of the line

Answer: The arrows show the appropriate destination for your dragging.
_____
Combining like terms in the given expression makes it simplify to ...
(2x -18x) +(14y) +(9 -10) = -16x +14y -1
We are to compare this expression with the offered expressions to see if they simplify to the same thing. We'll examine those left-to-right starting with the top row:
2x -18x +14y -19 = -16x +14y -19 . . . not the same
-2xy -1 . . . not the same
16x +14y -1 . . . not the same
9 -16x +14y -10 = -16x +14y -1 . . . equivalent
-16x +14y -1 . . . equivalent and simplified
2x -18x +14y -1 = -16x +14y -1 . . . equivalent

3. slope = 1/3; y-intercept = -1
4. slope = 2/5; y-intercept = 0
5. slope = -1; y-intercept = 4
Answer:
3) y = 1/3x - 1
4) y = 2/5x + 0 or just y = 2/5x
5) y = -1x +4

Step-by-step explanation:
The equation of the line in the graph is y= (blank) x+ (blank)
What is the slope-intercept form of the line with the point (0, 3) and a slope = -2?
O A. y = 2x + 3
O C. y = -2x + 3
D. y = -2x - 3
B. y = 2x - 3
Answer:
2nd choice OC.y=-2x+3
Step-by-step explanation:
The equation for the slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept. With these two numbers both given to us, we can just plug them in and get y=-2x+3.

You purchased concentrated cleaner that must be diluted (watered down)
before use. Container A is the cleaner, which is a 20% solution. Container B is
pure water. You are mixing together the contents of Container A and
Container B to produce 80 gallons of 5% solution. How many gallons from
each container are needed to create the 80 gallons of 5% cleaning solution?
Write your answers as integers only.
Container A: 20% Cleaning Solution =
gallons
Container B: Pure Water =
gallons
Answer:
The volume of the concentrated 80 gallons mixture is 20 gallons
The volume of water in the 80 gallons mixture is 60 gallons
Step-by-step explanation:
The given parameters are;
The content of Container A = The cleaner
The concentration of the cleaner = 20% solution
The content of Container B = Pure water
The concentration of the desired solution = 5%
The volume of the required solution = 80 gallons
Let x represent the volume of the concentrated solution and y represent the volume of water in the 80 gallons mixture
Therefore, we have;
20/100 × x + y×0 = 5/100×80
x + y = 80
y = 80 - x
20/100 × x + (80 - x)×0 = 5/100×80
0.2·x = 4
x = 4/0.2 = 20
x = 20 gallons
y = 80 - x = 80 - 20 = 60
y = 60 gallons
The volume of the concentrated solution (80 gallons mixture) = x = 20 gallons
The volume of water in the 80 gallons mixture = y = 60 gallons.
At a football stadium, 4% of the fans in attendance were teenagers. If there were 120 teenagers at the football stadium, what was the total number of people at the stadium?
Answer:
3000 people
Step-by-step explanation:
4% teenagers --> 120 teenagers were there
120/4 means 1% so 30 is 1%
1% times 100 is 100% so 30 times 100 equals 100% so 3000 is 100% of the people at the stadium
The revenue earned from a sporting event can be determined by the ticket price, $125 each.
Answer:
all whole numbers
all whole-number multiples of 125
Step-by-step explanation:
The domain and the range of a function is the set of input and output values of the function.
The domain is the set of all whole numbersThe range is the set of all whole numbersLet the number of tickets be x, and the revenue be y.
So, the revenue function will be:
[tex]\mathbf{y = 125x}[/tex]
The number of tickets cannot be less than 0.
So, the domain of the revenue function is:
[tex]\mathbf{Domain = [0,\infty)}[/tex]
The above means that, the domain is the set of all whole numbers
Similarly, the revenue cannot be less than 0.
So, the range of the revenue function is:
[tex]\mathbf{Range = [0,\infty)}[/tex]
The above means that, the range is also the set of all whole numbers (in multiples of 125)

Step-by-step explanation:
since the first 1000 fans get a ball and each ball costs $31 then u multiply
An object was dropped off the top of a building. The function f(x)=-16x^2+144f(x)=−16x 2 +144 represents the height of the object above the ground, in feet, xx seconds after being dropped. Find and interpret the given function values and determine an appropriate domain for the function.
Answer:
Step-by-step explanation:
Given the height at which an ogject dropped modelled by the function f(x)=-16x^2+144
The height of the body on the ground occurs at when f(x) = 0
0 =-16x^2+144
16x^2 = 144
x^2 = 144/16
x^2 = 9
x = 3
The ball reached the ground after 3 secs
The domain of a function is the input function that will make the function exist. Based on the function given, the function can exist on all given input value of x. Hence the domain of the function will be;
Domain =(-\infty, infty)
The domain of the function is required.
The domain of the function is the set of real numbers
[tex]x\in(-\infty,\infty)[/tex]
The function is
[tex]f(x)=-16x^2+144[/tex]
The y intercept of the function is
[tex]y=-16\times 0+144\\\Rightarrow y=144[/tex]
[tex](0,144)[/tex]
The y intercept is the maximum height here.
The x intercepts are the points where the object is on the ground.
They are
[tex]0=-16x^2+144\\\Rightarrow 16x^2=144\\\Rightarrow x=\pm\sqrt{\dfrac{144}{16}}\\\Rightarrow x=\pm3[/tex]
[tex](3,0),(-3,0)[/tex]
The domain of the function is the set of real numbers

$50. MP3 downloads cost $1.5 each. How many songs can he download
and still have $12
Answer:
25 MP3 downloads
Step-by-step explanation:
If he starts off with $50 then these are the steps
$50 - $1.50 = $48.50 for 1 MP3
$48.50 - $1.50 = $47.00 for 2
$48.50 - $1.50 = $45.50 for 3
then repeat that until we have $12
it doesnt give us exactly $12 but it gives us $12.50 reminder
So he can but 25 MP3 downloads and still have at least $12 remining

[tex]\displaystyle S_{27}=675[/tex]
Step-by-step explanation:
The sum of N consecutive natural numbers is given by:
[tex]\displaystyle S_N=\frac{N}{2}(F+L)[/tex]
We need to find the sum of the natural numbers between 12 to 38.
To calculate the required sum we have F=12, L=38, but we don't have the value of N.
From 12 to 38 there are 38 - 12 + 1 = 27 natural consecutive numbers, thus N=27.
Substituting in the formula:
[tex]\displaystyle S_{27}=\frac{27}{2}(12+38)[/tex]
[tex]\displaystyle S_{27}=\frac{27}{2}(50)[/tex]
[tex]\displaystyle S_{27}=27*25[/tex]
