find the rise and run
(please point the points on the graph}
Answer:
rise = -3
run = 4
rise/run = -3/4
Step-by-step explanation:
See figure for visual
The rise/run ratio gives the slope of the line
Take any two points on the line. I chose A(x1 = 2, y1 = 3) and B(x2 = 6, y2 = 0) as shown in the graph
For these two points the rise is (y2 - y1) = 0 - 3 = -3
The corresponding run is (x2 - x1) = 6 - 2 = 4
rise/run = -3/4 which is the slope of the line. This line has a negative slope - as x increases, y decreases
Not sure if that's what they are looking for.
Hope that helps
so, for context my teacher said it's C but I don't understand how the slope is negative.
the answer is:
A. slope: 9, y-intercept: -6

Answer:
part one:
6 3
22 1
30 0
part two:
0.50*s+4*a=15
Step-by-step explanation:
part one:
firstly:
6 individual songs cost 6*0.50= 3 dollars
she has 15 dollars so after downloading 6 individual songs that cost 3 dollars together
it means that she has only 15-3=12 dollars to download full albums
so 12/4=3 albums
because 4 dollar cost one album and with 12 dollars she can buy just 3 albums
secondary:
she downloaded 1 album
and one album cost 1*4=4 dollars
she has 15 dollars ,after buying 1 album
she has 15-4=11 dollars
so she can download 11/0.50=22 individual songs
so she can download 22 individual songs.
the last one:
she downloaded 30 individual songs
that all together cost 30*0.50=15 dollars
but she has 15 dollars at all so she cant buy any album because she spent all her money in individual songs.
because 15-15=0 money left
part two:equation
0.50*s+4*a=15

Objective: Identify the slope and y-intercept.
5.3.7
Find the slope and y-intercept of the graph of the equation.
y = 4x + 3
Select the correct choice and fill in any answer boxes in your choice below.
O A. The slope is
OB. The slope is undefined.
Answer:
y=4x+3 The slope is 4 and the y-intercept is 3
Step-by-step explanation:
Answer:
slope = 4, y- intercept = 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 4x + 3 ← is in slope- intercept form
with slope m = 4 and y- intercept c = 3
for most people, health club membership expenses are considered discretionary. alli lives in a big city and wants to join a health club. she researched monthly membership costs and found the following for health clubs within a 5-mile radius of her apartment. $65, $50, $44, $86, $90, $50, $35, $110, $70, $50, $35, $60, $56 a. what is the mean monthly membership fee? round your answer to the nearest cent. b. what is the median monthly membership fee? c. what is the mode monthly membership fee?
Order we can find the median is 56.
What is the mathematical mode?
The most common number, or the number that appears the most frequently. Example: Since the number 2 appears three times, more than any other number, it is the mode of the numbers 4, 2, 4, 3, and 2.A) 65 + 50+ 44+ 86 + 90 + 50+ 35 + 110 + 70 + 50 + 35 + 60+ 56/13
= 61.62
B) Arrange the number from small to large
35, 3,44,50,50,50,56,60,65,70,86,90,110
from this order we can find the median is 56.
c) we found that 50 was the most frequent acurrrence .
So, mode is 50.

My teacher keeps adamantly telling me that the answer is D, and I insist it’s B. Am I right or is she right?
My reasoning, question asks for an ALWAYS true statement. Question gives 6 defined points that if plotted will show it will need to cross the x axis twice to connect all the points while being continuous. Yet functions aren’t always straight and simple so two is the bare mininum and there may be more as in between those defined points the line may have crossed multiple times. However D and C assume its exactly 2 or more than 2, therefore they are wrong. If D and C merged together then that would be better than B. Yet B is still correct on the terms of being an “always” correct statement.
the picture below is more or less some quick mockup of what that might be, and yes, 2 solutions or zeros is the bare minimum, because we know only 5 points on this continuous line, but it could have jumped a few times before going forwards and we are not privy to those points.
well, we can say that
f(x) has more than one zero
f(x) has exactly two zeros
I think within the circumstance both are acceptable, exactly 2 zeros is also acceptable, but is not exclusively the only valid choice, if any we could say "exactly 2 zeros" is a subset of the superset "more than one zero".
kinda like saying Sandra has Felines and she also has 3 cats, well, 3 cats are an exact number, but the plural Felines contains them, so both statements are equally valid, one is more general than the other, is all
Samantha is taking out a loan for $17,452 at 6% simple interest for one year. How much interest will she pay?
Answer:
She will pay $1,047.12 interest for one year
Step-by-step explanation:
Simple Interest
Occurs when interest is calculated on the original principal only.
Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.
The interest earned is calculated as follows:
I=P.r.t
Where:
I = Interest
P = initial principal balance or loan
r = interest rate
t = time
Samantha takes out a loan for $17,452 at r=6%=0.06 simple interest for t=1 year. Calculating the interest:
[tex]I=\$17,452*0.06 *1[/tex]
I = $1,047.12
She will pay $1,047.12 interest for one year

If f(x)= 3x-5 and g(x)= x+2, then what is f(x)+g(x) ?
Answer:
4x - 3
Step-by-step explanation:
Givens
f(x) + g(x)
f(x) = 3x - 5
g(x) = x + 2
Equation
f(x) + g(x) = 3x - 5 + x + 2
Solution
f(x) + g(x) = 4x - 3 Collected like terms from the equation.
Remark
If you think of f(x) and g(x) as equal to different y values, it might help you to solve questions like this.

Answer:
C. 8
Step-by-step explanation:
I almost thought this was going to be Pythagorean Theorem, but no.
Use Cosine Law:
cos θ = [tex]\frac{10^2 + 21^2 - 17^2}{2(10)(21)}[/tex]
θ = cos−1(0.6)
θ = 53.130...
Now use the SOHCAHTOA ratio for sine ([tex]\frac{opposite}{hypotenuse}[/tex]) to find x now that you have one angle:
sin θ = [tex]\frac{x}{10}[/tex]
x = 10sinθ (θ isn't needed to be written out as it is shown in the equation above)
x = 8

Answer:
He pays taxes on the amount after the discount. So 10% of $40.50 versus $45.
Step-by-step explanation:
10% on $40.50 = $4.05
10% on $45.00 = $4.50
when you take 10% of $45, you're left with $40.50 because you'd do 40*10/100. when you go to add the 10% tax, you are no longer taxing $45, you're taxing $40.50 which is $4.05. 40.50+4.05=44.55
