Find the slope of the line through the given points.* (-13, 10), (10, -13)
===========================================
Work Shown:
Let's apply the slope formula to get...
m = (y2 - y1)/(x2 - x1)
m = (-13 - 10)/(10 - (-13))
m = (-13 - 10)/(10 + 13)
m = -23/23
m = -1
The slope is -1
-----------
Extra info:
The slope is the rate of change. Specifically it's the change in y over the change in x. So that's why we divide the (y2-y1) over the (x2-x1). The (y2-y1) is the change in y; the (x2-x1) is the change in x.
You can think of it as
slope = rise/run
rise = y2-y1 = change in y
run = x2-x1 = change in x
A certain computer loses half of itş value every two years.
If the value of the computer after 3 years is $425, what was the initial
value of the computer?
A. $601.04
B. $850.00
C. $1,202.08
D. $2,404.16
The initial value of the computer is 1,700.
What is the meaning of initial value?The initial value is the beginning output value.
We have given that the computer losses half of its value, and If the value of the computer after 3 years is 425,
we have to calculate, what was the initial value of the computer,
Suppose that the initial value of computer is x
So after two years it will be,
for the second year, it is X/2
for the third year, it is X/2
In the fourth year, it is X/4
we have given that after 3 years, the value of the computer is 425 Therefore we can write it as,
X/4=425
X=4(425)
X=1700
Therefore, the initial value of the computer is 1,700

The length of a rectangular table is two times its width. If the perimeter of
the table is 2,000 ft, set up an equation to find the width (w) of the table.
1. 2000 = 2(2W + W)
2. 1000 = 2(3W+ W)
3. 2000 = 2(2wx W)
4. 2000 = 2(3wx w)
Answer:
1. 2000 = 2(2W + W)
Step-by-step explanation:
perimeter = 2(L + W)
L = 2W, so:
perimeter = 2(2W + W)

A minor league baseball 112 games in a session. If the team won 16 more than 3 times as many games as they lost, how many wins and losses do they have
Answer:
Won = 88 gamesLost = 24 gamesStep-by-step explanation:
The number of games for the session is 112 so all the wins and losses should add up to 112.
Assume that the number of times they lost is x. The number of times they won would then be: 16 + 3x
Total expression is therefore:
16 + 3x + x = 112
16 + 4x = 112
4x = 112 - 16
x = 96/4
x = 24
They lost 24 games. Number of games won is:
= 112 - 24
= 88 games
Which expression is equivalent to5(h+9)
Answer:
The answer would be 5h+45
Step-by-step explanation
5 (h+9)
You need to convert this equation into the equation
you multiply 5 by h and get 5h
Then multiply the same number outside the parenthesis, 5, by 9 which will give you the answer 45
Once you have 5h and 45 just put it together with the addition symbol which will will equal:
5 (h+9) = 5h + 45

Answer:
what she sells each t-shirt for.
Step-by-step explanation:
if f(x) is the profit and x=# of t-shirts,
the rate of change is 8, which is what she sells each t-shirt for.
The 100 that is subtracted, is the money that she spent on materials.
For eg, if she sells 8 t-shirts she makes $64, but she spent $100 before and didn't gain any profit, having not made up $36 from what her original spending was.

Answer:
x = 13.3125
Step-by-step explanation:
Since it is a square, divide the area (225) by 4: 56.25
Now solve for x
56.25 - 3 = 53.25
53.25 / 4 = 13.3125

Answer:
y=-3x+10
Step-by-step explanation:
Since you know that the equation of the line is perpendicular to 1/3, you have to find the inverse of 1/3. You swap the denominator and numerator and make the number negative. In this case, it will be -3. Now that you know the slope is -3, you can use the equation y-y1=m(x-x1) where m is the slope. We know that the point (2,4) is in the graph so we can plug it into the equation. y-4=m(x-2). We know that the slope is -3 so we can plug it into the equation. y-4=-3(x-2). Simplify this to get y-4=-3x+6. Simplify this to get y=-3x+10. This means that the answer is y=-3x+10.

Name a positive angle between 0 radians and 2π radians that is coterminal with an angle in standard position whose measure is −3π2 radians.
Answer:
The positive angle between [tex]0[/tex] and [tex]2\pi[/tex] radians that is coterminal with [tex]\theta = -\frac{3\pi}{2}\,rad[/tex] is [tex]\theta = \frac{\pi}{2}\,rad[/tex].
Step-by-step explanation:
GIven that the measure of the known angle is [tex]-\frac{3\pi}{2}[/tex] radians and that such angle belongs to a set of angles in terms of revolutions (with a period of [tex]2\pi[/tex]) done either clockwise or counterclockwise, we can represent the family of coterminal angles with the following expression:
[tex]\theta = -\frac{3\pi}{2}\pm (2\pi\cdot i)[/tex], for [tex]i \in \mathbb{N}_{O}[/tex] (1)
Where [tex]i[/tex] is the index of the coterminal angle.
According to the statement, we must name a positive angle between [tex]0[/tex] and [tex]2\pi[/tex] radians, which can be found by the sign [tex]+[/tex] and [tex]i = 1[/tex]. Hence, we find the required angle:
[tex]\theta = -\frac{3\pi}{2} + 2\pi[/tex]
[tex]\theta = \frac{\pi}{2}\,rad[/tex]
The positive angle between [tex]0[/tex] and [tex]2\pi[/tex] radians that is coterminal with [tex]\theta = -\frac{3\pi}{2}\,rad[/tex] is [tex]\theta = \frac{\pi}{2}\,rad[/tex].
