Suppose a friend tells you she paid a total of $20,500 for a car, and you’d like to know the car’s list price (the price before taxes) so that you can compare prices at various dealers. Find the list price of the car if your friend bought the car in:
Roswell, where the sales tax is 6.5%
Given :
Total amount paid for the car is, A = $20,500.
Sales tax is 6.5%.
To Find :
The list price i.e. price without tax.
Solution :
Let, list price is P.
P = A - 0.65A
P = A( 1 - 0.65 )
P = 20500×( 1 - 0.065 )
P = $19167.5
Therefore, the list price of car is $19167.5 .

Answer: p = 1
Step-by-step explanation:
2/5 + p = 4/5 + 3/5p
-2/5 -2/5
p = 2/5 + 3/5p
-3/5p -3/5p
2/5p = 2/5
Divide both sides by 2/5
p = 1

f(x)=6x+4. Find the inverse of f(x).
Answer:
c
Step-by-step explanation:
f(x)=6x+4
y=6x+4
x=6y+4
6y=x-4
y=(x-4)/6
f^-1(x)=(x-4)/6
Answer is Option-C
How to find Inverse Function:
1. First, replace f(x) with y. This is done to make the rest of the process easier.
2. Replace every x with a y and replace every y with an x.
3. Solve the equation from Step 2 for y.
(Here), Given
f(x) = 6x + 4
Let's inverse function be y.
y = 6x + 4
First step is to switch the positions of x and y.
Inverse: x = 6y + 4
x - 4 = 6y
=> y = (1/6) * (x - 4)
Option-C

~I hope I helped you :)~
I hate math
First thing's first, PEMDAS. There's nothing to solve in the parenthesis, and there are no exponents, so use multiplication next. 6 • (x-2) and -8 • (x-3)
Your equation after should be
5x + 6x - 12 - 8x + 24
Next would be addition, don't forget it's always left to right.
11x - 12 - 8x + 24
Subtract twelve from the total (or in this case just from 24, and then add the remaining values (that are possible).
11x - 8x + 12
Next, subtract the two remaining x values.
3x + 12
And there you have it. Easy peasy.
If the case is trying to find x, just solve it like this.
3x = -12
x = 4

A ball is launched into the sky at 54.4 feet per second from a 268.8 meter tall building. The equation for the ball’s height, h, at time t seconds is h = -3.2t^2 + 54.4t + 268.8. When will the ball strike the ground?
Answer:
7.41
Step-by-step explanation:
Vertical component:
S = 268.8
U = 0
V =?
A = 9.8
T=?
S = ut + 0.5at^2. u = 0
268.8 = 0.5x9. 8xt^2

3+5x-4-7x=2x-4x+1 i have to solve this problem
Answer:
Undetermined x=x
Step-by-step explanation:
First, you need to simplify each side by combining like terms:
(5x - 7x)(+3-4) = (2x - 4x) +1
-2x - 1 = -2x + 1 is your simplified expression.
After adding 1 to both sides, you're left with: -2x = -2x
You can divide both sides by -2, you'd get: x = x
Therefore, it's undetermined. Meaning, there are no possible solutions or there's infinite solutions. In this case, there's infinite solutions.

Answer:

Step-by-step explanation:
Always
Sometimes
Never
Always
Answer:
always,sometimes,never,always
Step-by-step explanation:
Equilateral triangles are
always
acute triangles. Yes, because acute is always 60 degrees, and equilateral is basically your average triangle, so its corners have 60 degrees.
Scalene triangles are
sometimes
acute triangles. Scalene triangles always dont have that sharp corner..they sometimes do, the sharp turn which is 60 degrees, ACUTE IS ALWAYS 60 DEGREES.
Right triangles are
never
acute triangles. A right angle cant be a acute, not 60 degrees..
Obtuse triangles are
always
isosceles triangles. Isosceles means atleast 2 of the sides look the same, i included how to recognize obtuse, right,etc
The equation for line g can be written as y = x + 5. Parallel to line g is line h, which passes through the point (-6, -4). What is the equation of line h? SHOW WORK PLEASE
Answer:
y=x+2
Step-by-step explanation:
we know the slopes have to be equal because the lines are parallel, so the slope is 1, or written as x. plug the point given, (-6,-4), and the slope, 1, into the y=mx+b equation to find the y-intercept. then solve. then put the slope and y-intercept together for the equation of line h.
y=mx+b, m=1, x=-6, y=-4
-4=(1)(-6)+b
-4=-6+b
2=b
y=x+2

Find the slope intercept equation of the line
Answer:
Step-by-step explanation:
slope-intercept formula looks like [y=mx + b]
use two points to find the slope.. or look at the graph carefully to see it there are easy points to count from.... hmmm
yes.. this is very easy to just count.. no math needed :P
the slope is posive. b/c the graph looks like you are walking up hill.. and it's rise over run is 2/1 .. so the slope is 2
then by looking at the graph I can also see that when x = 0 the line pass exactly thur +1.. sooo that tells me all I need to know for the sloop-intercept formula

Does anyone know please
Answer:
8 hours and 54 minuter
Step-by-step explanation:
1 hour is equal to 60 minutes
we have 8 hours and 0.9 hours
0.9*60=54 minutes
we have 8 hours and 54 minuter
Answer:
The last one
Step-by-step explanation:
First you need to figure out how many minutes are in 0.1 hours
you can do this by dividing 60 minutes by 10
you get 6
multiply 6 and 9 so that you can find out how many minutes 0.9 hours are
this leaves you with 54 minutes
so your answer is 8 hours and 54 minutes
