Find an equation of the vertical line through (-6,6). If possible, write a formula for a linear function whose graph is the given line
The equation for a vertical line passing through (-6,6) is x = -6. However, this line cannot be represented by a formula for a linear function in the form y = mx + b, as a vertical line has an undefined slope.
Explanation:A vertical line in a coordinate plane, such as the one passing through point (-6,6), has an equation format of x = c where c represents a constant value. In this particular case, as the line passes through the x-coordinate of -6, the equation of the vertical line is x = -6.
As for creating a formula for a linear function whose graph is this given line, that is not possible. Linear functions can be represented by the slope-intercept form "y = mx + b" where m represents the slope and b is the y-intercept. However, a vertical line does not have a slope (it is considered undefined or infinite), and therefore can't be represented as a linear function in this form.

32 is 20% of what number?
A) 64
B)89
C)128
D)160
Answer:
D) 160
Step-by-step explanation:
20% × n = 32
20 /100 × n = 32
Multiplying both sides by 100 and dividing both sides by 20,
n = 32 × 100 /20
n = 160
Answer:
D, 160
Step-by-step explanation:
Hello!
To find the answer to this question, we have can represent any number as "n."
Since 20% is the same as [tex]\frac{20}{100}[/tex], we have:
[tex]\frac{20}{100}[/tex] * n = 32
Now we multiply both sides by 100 to get rid of the fraction:
20n = 3200
And divide both sides by 20:
n = 160.
Thus, the answer is [tex]\boxed{160{\text{\:or\:D.}}}[/tex]

Find the equation of the line that is perpendicular to y = 2x + 8 and passes though the point (8, –8).
Answer:
y= -1\2x-4
Step-by-step explanation:
y=mx+c
perpinicular means you flip the slop and change the sign so the slope(m) become -1\2
y=-1\2x+c
since he gives you (8,-8) meaning x=8 and y= -8
we substitute
-8=(-1\2 x 8) +c
now we isolate c
-8+4=c
c=-4
the equation will be
y= -1\2x-4

An online media service offers video and music downloads. Each download of a song costs $1.50. Each download of a video costs 2 times as much as the song download. You have a credit of $60. How many songs can you purchase after buying 15 videos?
Answer:10
Step-by-step explanation:
if a song costs $1.50 and a video is 2 times that amount of a song, then the video would cost $3. you have a balance of $60. you by 15 videos to start. i multiplied $3 by 15 to get the cost of the movies, witch is $45. after i got the cost of the movies i subtracted the $45 from the over all amount, i got 15. now to the songs. i have $15 to get music. 2 songs costs $3( 1.50+1.50= 3.00). 4 songs would cost $6. 8 songs would cost $12. after that i just added 1.50 until i hit a total of 15. so you can get 10 songs for $15
After buying 15 videos, you can purchase 10 songs with your $60 credit. Each video costs $3.00 and each song $1.50. After buying the 15 videos for $45, you have $15 left for songs.
Explanation:The subject matter of this question falls under Mathematics, specifically operations involving money and elementary algebra. This kind of problem is typically encountered by middle school students, hence the grade level.
In order to answer the question, here's a step by step solution: First, we need to know the cost of downloading a video. Since each download of a video costs 2 times as much as the song download, and the song download costs $1.50, then the video download costs 2 * $1.50 = $3.00. If you plan to buy 15 videos, the total cost would be 15 videos * $3.00/video = $45.00.
Subtracting this amount from your $60 credit, you'll have $60 - $45 = $15 left. Given that the cost of a song download is $1.50, you can therefore purchase $15 / $1.50/song = 10 songs.
So, after buying 15 videos, you can still purchase 10 songs with your $60 credit.

Actually, the lesson is giving you wrong information. The exponential function written in the example does not work for the point (4, 24).
Here's another way to look at it.
Given
two points: (x1, y1) and (x2, y2)
Solution
The exponential function can be written as ...
y = (y1)(y2/y1)^((x -x1)/(x2 -x1))
Example
For the example points, the function would be ...
y = (6)(24/6)^((x-2)/(4-2)) = 6·4^(x/2 -1) = (6/4)(4^(1/2))^x = (3/2)2^x
Check
For x=2, y=(3/2)2^2 = 6. For x=4, y = (3/2)2^4 = 24.
You will notice that we figure out "b" and "a" as a part of the process of simplifying the equation. The equation would work perfectly well without simplification.
_____
1. Given points (2, 50) and (3, 250), the equation is ...
f(x) = 50(250/50)^((x -2)/(3 -2)) = 50·5^(x -2) = (50/25)5^x
f(x) = 2·5^x . . . b = 5; a = 2
__
2. Given points (1, 3) and (2, 9/2), the equation is ...
f(x) = (3)(3/(9/2))^((x -1)/(2 -1)) = (3)(2/3)^(x -1) = (3/(2/3))(2/3)^x
f(x) = (9/2)(2/3)^x . . . b = 2/3; a = 9/2
__
3. Given points (3, 32) and (4, 128), the equation is ...
f(x) = (32)(128/32)^((x -3)/(4 -3)) = (32)4^(x -3) = (32/64)4^x
f(x) = (1/2)4^x . . . b = 4; a = 1/2
_____
Additional comments
The usual rules of exponents are useful in this:
a^(b+c) = (a^b)(a^c)
a^(bc) = (a^b)^c
a^-b = 1/a^b

WHEN YOU ADD 20 AND 20 IT WILL GIVE 40
The value of h using concept of missing angles is: h = 55
How to find the missing angle?We know that the sum of angles on a straight line is 180 degrees.
Thus, the remaining two internal angles of the triangle are:
180 - 2h and 180 - 2h
We also know that the sum of angles in a triangle is 180 degrees. Thus:
180 - 2h + 180 - 2h + 40 = 180
400 - 4h = 180
4h = 400 - 180
4h = 220
