since the slope is decreasing, it is negative.
Answer:
So the slope is -5/2.
Step-by-step explanation:
You want to look at the line to find the slope of it. For slope you want to find rise/run. This is the same as: change in y/change in x. awe have 2 points (the blue dots) to find slope. With this, let's find the change in y and the change in x. For those 2 dots, the change in y is down 5, which means -5 (if it was up 5 it would be 5)For change in x, it is to the right 2, which means 2 (if it was 2 to the left then it would be -2). Therefore, the slope would be change in y/change in x which is -5/2 (the 3rd option)Related Questions
Melanie is going to invest in an account paying an interest rate of 3.1% compounded
daily. How much would Melanie need to invest, to the nearest dollar, for the value of
the account to reach $11,900 in 14 years?
Answers
Using compound interest, it is found that Melanie would need to invest a value of $7,710.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In this problem, we have that:
Rate of 3.1%, hence [tex]r = 0.031[/tex].Compounded daily, hence [tex]n = 365[/tex].Value of $11,900 in 14 years, hence [tex]t = 14, A(t) = 11900[/tex].The amount she needs to invest is P.Hence:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]11900 = P\left(1 + \frac{0.031}{365}\right)^{365(14)}[/tex]
[tex]1.54339P = 11900[/tex]
[tex]P = \frac{11900}{1.54339}[/tex]
[tex]P = 7710[/tex]
Melanie would need to invest a value of $7,710.

In my garden I planted 1 2/3 rows of seeds. The crows came along and ate 1 1/5 of the seeds. How many rows are left?
Answers
Given:
Seeds planted = [tex]1\dfrac{2}{3}[/tex] rows
Crows ate = [tex]1\dfrac{1}{5}[/tex] rows
To find:
The remaining rows of seeds.
Solution:
According to the question,
Remaining rows of seeds = Seeds planted - Crows ate
[tex]=1\dfrac{2}{3}-1\dfrac{1}{5}[/tex]
[tex]=\dfrac{1(3)+2}{3}-\dfrac{1(5)+1}{5}[/tex]
[tex]=\dfrac{3+2}{3}-\dfrac{5+1}{5}[/tex]
[tex]=\dfrac{5}{3}-\dfrac{6}{5}[/tex]
Taking LCM, we get
[tex]=\dfrac{5(5)-3(6)}{15}[/tex]
[tex]=\dfrac{25-18}{15}[/tex]
[tex]=\dfrac{7}{15}[/tex]
Therefore, [tex]\dfrac{7}{15}[/tex] rows of seeds are left.
Given the condition that you know a student has purchased at least one of the items. What is the probability as a percentage that they purchased only one of the items?
Answers
Step-by-step explanation:
This is a case of conditional probability, in which we have to find the probability of ocurance of event E when when event F has already ocured.
To find the probability of at least one of something, calculate the probability of none and then subtract that result from 1.
That is, P(at least one) = 1 – P(none)

Step-by-step explanation:
Hey there!
Given eqautions are:
y = 2x + 1......... (i)
y = 4x - 3...........(ii)
Putting eqaution (ii) in eqaution (i), we get;
4x - 3 = 2x + 1
~ Keep like terms on same side.
4x - 2x = 1+3
~ Perform operations. ( +, -, *, /)
2x = 4
x= 4/2
Therefore, X= 2.
Putting the value of X in eqaution (i)
y = 2x+1
y = 2*2+1
Therefore, y= 5.
Therefore, the ordered pair is (2,5).

x = 5, ST = 45
Step-by-step explanation:
Given that m bisects SU, then
ST = TU , that is
9x = 4x + 25 ( subtract 4x from both sides )
5x = 25 ( divide both sides by 5 )
x = 5
Thus
ST = 9x = 9 × 5 = 45

Two apps on your phone take away points for using your phone at school. You have 140 points on the first app and 80 points on the second app when a school day begins. Each time you check your phone, you lose 10 points on your first app and $p$ points on your second app. After you check your phone ten times, you have the same number of points on each app. Find the value of $p$
Answers
Answer: p = 4
Step-by-step explanation:
For app one, you start with 140 points, and you lose 10 each time you check your phone.
Then, if you check your phone x times, you will have:
140 - x*10 points in total.
For app two, you start with 80 points, and you lose p points each time you check your phone.
Then, if you check your phone x times, you will have:
80 - x*p points left
We know that when x = 10, you have the same number of points in both apps, then we have the equation:
140 - (10)*10 = 80 - (10)*p
We can solve this for p
140 - 10*10 = 80 - 10*p
140 - 100 = 80 - 10*p
40 = 80 - 10*p
10*p = 80 - 40
10*p = 40
p = 40/10 = 4

Answer:
x = 36
Step-by-step explanation:
The total angles of a triangle is 180 degrees
(2x - 17) + (x + 53) + x = 180
2x - 17 + x + 53 + x = 180
4x + 36 = 180
Subtract 36 from both sides;
4x = 144
Divide both sides by 4;
x = 36
Can anyone help me answer these, or at least show me how to do one?
Answers
Answer:
Step-by-step explanation:
1) The function f(x) = x is a straight line rising to the right and passing through the origin at an angle of 45 degrees This means this it passes though the points ..... (-2, -2), (-1, -1), (1, 1), (2, 2) .......
If g(x) = f(x) + 4 then g(x) will be a straight line parallel to f(x) where each point on g(x) is 4 units vertically up from each point on f(x). Its a translation of f(x) up 4 units.
The slope of both graphs is 1.
2) This line (g)x passes through the origin but has slope 1/3.
