Write the equation of the line described
Step-by-step explanation:
slope = x factor = - 5/2
Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1
New slope = 2/5 = m
y = mx + b
from the point given y = 2 | x = -4
2 = (2/5 × -4 ) + b
2 = - 1.6 + b
b = 3.6
line equation
[tex]y = \frac{2}{5} x + 3.6[/tex]

Answer:
y = x - 8
Step-by-step explanation:
There's no magic method to doing these, and problem 21 makes it harder to see a pattern by using inputs that are not consecutive integers (like problem 20 does)!
Looking at inputs 20 and 21, the outputs are 8 less than the inputs. Check the other inputs and notice that the same pattern holds up.

show that a^12 can be written as a perfect square and a perfect cube
Answer:
Step-by-step explanation:
Doing this the long way, write a^12 as a product of "a"s
a^12 = a * a * a * a * a * a * a * a * a * a * a * a
Now group them into groups of 4
a^12 = a * a * a * a * a * a * a * a * a * a * a * a
There are 3 groups of 4 so you can write it as [(a^4)]^3 which is a cube
Now do the same thing with groups of 6s
a^12 = a * a * a * a * a * a * a * a * a * a * a * a
a^12 = (a^6)^2
So the two answers are
Perfect cube: [(a^4)]^3
Perfect square: (a^6)^2

this is my brothers math homework can someone help w the what is the meaning question
The answer is [tex]24/4=6 \hspace{0.1cm} and \hspace{0.1cm}4*6=24[/tex]. "unknown factor" pertains to finding an unknown value in a multiplication problem, while "quotients" refer to the results obtained in division operations.
Both concepts are fundamental in arithmetic and algebraic calculations.
In mathematics, "unknown factor" and "quotients" are related to multiplication and division, respectively:
1. **Unknown Factor:**
- An "unknown factor" refers to a number or variable that you want to find or determine in a multiplication problem.
- In the context of an equation like "a * b = c," where "a" and "b" are known values or variables, and "c" is the result of the multiplication, you might be trying to find the value of "a" or "b." The unknown factor is the value that you don't initially know, and you need to solve for it.
- For example, if you have the equation "3 * x = 15," the unknown factor is "x," and to find its value, you would need to divide both sides of the equation by 3, yielding "x = 5."
2. **Quotients:**
- "Quotients" is the plural form of "quotient," and it refers to the result of a division operation.
- In division, the quotient is the number that you get when you divide one number (the dividend) by another number (the divisor).
- For example, in the division problem "12 ÷ 4," the quotient is 3 because 12 divided by 4 equals 3. Here, 3 is the result or quotient of the division operation.
- Quotients can be whole numbers, fractions, or decimals, depending on the numbers being divided and the division process.

Refer to the graphic novel frame below. The brochure says that the rope is 500 feet long. Jacob drew a triangle in the sand that is similar to the actual triangle formed by a parasailer and the boat. Use the properties of similar triangles to determine the parasailer's height above
To solve this problem use the property of similar triangles,
"Corresponding sides of the similar triangles are proportional"
By using this property, height of the parasailer is 160 feet.
From the figure attached,
In ΔPQR, a parasailer is a at point P and a boat is at R.Actual length of the rope PR = 500 ftJacob drew a similar triangle ABC in which parasailer is at A and the boat is at C.Let the height (PQ) of the parasailer = x ft
Height of the parasailer AB = 25 ft.
And the length of the rope AC = 2.5 ft.
Since, both the triangles ΔABC and ΔPQR are the similar triangles, their corresponding sides will be proportional.
[tex]\frac{AB}{PQ}=\frac{AC}{PR}[/tex]
[tex]\frac{2}{x} =\frac{2.5}{200}[/tex]
[tex]x=\frac{200\times 2}{2.5}[/tex]
[tex]x=160[/tex] ft
Therefore, height of the parasailer is 160 feet.

What is the image point of (-8,9)(−8,9) after a translation right 3 units and down 1 unit?
Answer:
(-5,8)
Step-by-step explanation:
The left number represents the x-axis, the right one the y-axis. A translation to the right means in the positive direction on the x-axis, which is why we add 3 to -8 which gives us -5. Down on the y-axis is in the negative direction, which means we have to subtract 1 from 9, giving us 8.
Answer:
the answer is the same since it is the same numeral so in terms of y=mx+c and x1/y1 would be inversely proportional to x2/y2 which is perfectly direct proportional to x3/y3×2 and then dy over dx is the problem of integration so you use (x2/x3÷y2/y3)×x1^y1

Name a pair of vertical angles, a straight angle, and two acute angles
other than
Step-by-step explanation:
While there are no examples available, there is the room to understand each angle type you listed, vertical angles are angles that are opposite from each other, and they are congruent (they have the same angle in degrees) now, imagine that for vertical angles, they are in an X top and bottom are equal, and the two sides are equal. For a straight angle, that is usually two angles that are right angles (90 degrees) back to back, meaning when you add 90 and 90 degrees together, you get a straight line or a 180 degree angle. An example of an acute angle is any angle less than 90 degrees, that is a real number, so imagine 25, 40, and 60 as all acute angles.
Hope this helps you identify them in your problem!

Nina can braid 144 inches of rope in 3 hours find her unit rate round your answer to the nearest thousand
Answer:
48 inches
or
0.8 minutes
Step-by-step explanation:
To find the unit rate of inches per hour, divide 144 by 3.
144÷3=48
You don't need to round because there are no decimals.
To find the time to braid 1 inch, first multiply 3 by 60 (because there are 60 minutes in 1 hour).
3×60=180
Then divide 144 by 180.
144÷180= 0.8
You don't need to round because there are no thousandths.

A line goes through the points (7, 3) and (11, 5). What is the equation of the line? Answer quick pls.
Step-by-step explanation:
slope = ( y2-y1) / (x2-x1)
= (5-3) / (11-7)
= 1/2
y= mx+ b
m = slope
5 = 11/2 + b
5 - 5.5 = b
b = -0.5
the equation y = 1/2(x) - 0.5
The equation of line is x-2y =1
How do you find equation of a line?To find an equation of a line given the slope and a point.Identify the slope.Identify the point.Substitute the values into the point-slope form, y − y 1 = m ( x − x 1 ) . y − y 1 = m ( x − x 1 ) .Write the equation in slope-intercept form.Slope-intercept form: The equation of line with slope m and making an intercept c on the y-axis, is y = mx + c.
Given coordinates are:
(7, 3) and (11, 5)
now, equation of line
(y- y1)= (y2-y1)/(x2-x1) *(x-x1)
y-3 =(5-3)/(11-7) *(x-7)
y-3= 2/4 * (x-7)
y-3= 1/2(x-7)
2y-6= x-7
x-2y =1
Hence, the equation of line is x-2y =1.
