A triangle has vertices on the coordinate grid at points D (3, -3), E (0, 2), and F (-1, -3). What is the length, in units, of DF ?
A triangle is a polygon with three sides and three angles.
The distance between two points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] on the coordinate plane is given by:
[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Given A triangle with vertices at points D (3, -3), E (0, 2), and F (-1, -3). The length of side DF is given as:
[tex]DF=\sqrt{(-1-3)^2+(-3-(-3))^2}=4\ units[/tex]

PLEASE HELP I WILL BRAINLIST
Answer:
8
Step-by-step explanation:
Since they intersect you can just solve for x and y
since y=-4x and y=x^2+2x+8, you can set -4x=x^2+2x+8
add 4x to both sides to make 0=x^2+6x+8
and factor out (x+4)(x+2)
so the solutions for x are -4 and -2
then insert the two values for x into the first equation
so y=-4(-4) and y=-4(-2)
so y=16 and y=8 when x=-4 and x=-2
so the smallest value for y in both equations is 8

If HI = 7, find KL.
Answer:
14
Step-by-step explanation:
(I go to a french school, so excuse my terminology, which might not always be correct)
The angle we can see, in GHI, is equal to 121°. JKL has an identical angle, meaning JKL is an enlargement (probably the wrong term, I apologise) of GHI. This means we can use the length of it's sides to find KL.
GH and GI are both multiplied by two (GH = 4 becomes JK = 8, GI = 5 becomes JL = 10) meaning you must multiply HI by 2 to find KL.
2*7 = 14
KL = 14

a polygon has perimeter 15 units.it is dilated with a scale factor of 3/5.what is the perimeter of its image
Given what we know, we can confirm that the perimeter of the image is 9 units.
Perimeter and Scale factor.To calculate the perimeter of a shape, we must add the length of all of its sides. When we dilate a shape, we multiply each of its sides by our scale factor.Our scale factor is [tex]\frac{3}{5}[/tex], which corresponds to 0.6 in decimal form Taking the sum of 15 as the perimeter of the preimage and multiplying by 0.6 gives us the perimeter of the image which is 9 units.Therefore, given that [tex]15units * \frac{3}{5} = 9 units[/tex], we can confirm that the perimeter of the image is 9 units.

Which expression represents the area of the figure?
Answer:
Option A
The Area of the given figure is 5x²/2 + 3x/2 - 4
Step-by-step explanation:
For a given Trapezoid
side a = x + 7
side b = 4x + 1
height (h) = x - 1
Now, Area of Trapezoid
Formula:A = ½ (a + b) × h
A = ½ (x + 7 + 4x + 1) × (x - 1)
A = ½ (5x + 8) × (x - 1)
A = ½ (5x² - 5x + 8x - 8)
A = ½ (5x² + 3x - 8)
A = 5x²/2 + 3x/2 - 8/2
A = 5x²/2 + 3x/2 - 4
Thus, The Area of the given figure is
5x²/2 + 3x/2 - 4

not sure
Step-by-step explanation:
To find the surface area, use this rectangular prism surface area
formula:
Surface Area =
[(Length x Width) + (Length x Height) + (Width x Height)] x 2
Example: The surface area of a rectangular prism with length of
3 inches, width of 4 inches, and height of 5 inches:
Surface Area = [(3 x 4) + (3 x 5) + (4 x 5)] x 2
Calculated out this gives a surface area of 94 Square Inches.

The work of a student trying to solve the equation 4(2x − 1) = 11 + 3x + 5 is shown below:
Step 1: 4(2x − 1) = 11 + 3x + 5
Step 2: 8x − 4 = 16 + 3x
Step 3: 8x + 3x = 16 − 4
Step 4: 11x = 24
Step 5: x = 2.18
In which step did the student first make an error and what is the correct step?
Step 2: 8x − 1 = 16 + 3x
Step 2: 8x − 8 = 6 + 3x
Step 3: 8x − 3x = 16 + 4
Step 3: 8x + 3x = 16 − 8

This can be obtained as follow:
... x² + 3y² – 6xy
+ 2x² – y² + 8xy + 8
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
3x² – 2y² + 2xy + 8

This can be obtained as follow:
–3x² + 4y² + 3
+ 4y² – 5
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
–3x² + 8y² – 2

Logan is going to invest in an account paying an interest rate of 3.1% compounded continuously. How much would Logan need to invest, to the nearest ten dollars, for the value of the account to reach $990 in 6 years?
Answer:
yessir
Step-by-step explanation:
Answer: Rounded to the nearest $10 he would have to invest $830
Step-by-step explanation: While I am not completely familiar with this sort of math I am still relatively confident that I got the correct answer. Using the formula A = Pe^rt. First we can convert the percentage to a decimal so it can be used efficiently in the formula. So r = 3.1/100 which in turn equals 0.031 which is our decimal. Now we can simply input our information into the formula for our answer so follow along
A = 830 * e ^(0.031 * 6)
A = 830(2.718281828459045)^(0.186)
A = 999.67
And of course this is not exactly $990 because the question stated to round the original investment amount to the nearest 10 dollar. This should be your answer and if you have any other questions about this please do not hesitate to reach out :)
Factor out the GCF:
-36n^3 + 6n^2
Answer:
Step-by-step explanation:
36n³ = 2 * 2 * 3 * 3 * n * n *n
6n² = 2*3 * n * n
GCF = 2 * 3 * n * n = 6n²
-36n³ = 6n² * (-6n)
-36n³ + 6n² = 6n²*(-6n) + 6n²
= 6n² ( -6n + 1)

Step-by-step explanation:
here's your solution
=> total money received by them = $1600
=> the given ratio are 7:5:4
=> let the ratio be X ,now
=> Maria = 7X
=> Carolina = 5X
=> Pedro = 4X
=> we know whole money = $1600
=> so, adding all
=>. 7x + 5x + 4x = $1600
=> 16x = $1600
=> x= $1600/16
=>. x = $100
now Maria = 7*100 = $700
Carolina = 5*100 = $500
Pedro = 4*100 = $400

A high school play is sold tickets to their performance and wanted to see how many tickets were adults (x) and how many were students (y). There were 50 more adult tickets sold compared to student tickets. Adult tickets were $5, student tickets were $2, and they collected a total of $950. Write 2 equations and solve this system.
Answer:
70
Step-by-step explanation:
The equation are x = y + 50 and 5x + 2y = 950
Firstly, let x represent the number of adult tickets sold and let y represent the number of student tickets sold.
Since there was 50 more adult tickets sold compared to student tickets, hence this statement can be represented by the equation:
x = y + 50 (1)
Also, they collected a total of $950. Each adult ticket was $5 while female ticket was $2, hence:
5x + 2y = 950 (2)
5(y + 50) + 2y = 950
y = 100
x = 100 + 50
x = 150
Solving equations 1 and 2 simultaneously gives y = 100 and x = 150
Therefore they was 150 adult tickets and 100 student tickets

One pipe can fill a pool in 9 hours. Another pipe can fill the pool in 6 hours. How long would it take them to fill the pool if they were working together?
Answer:
3.6 hours or 3 hours and 36 minutes.
Step-by-step explanation:
If the first pipe can fill the pool in 9 hours that means that in 1 hour it fills [tex]\frac{1}{9}[/tex] of the pool, we use the same logic for the second pipe and conclude that in 1 hour it feels up [tex]\frac{1}{6}[/tex] of the pool. If both were to fill the pool together that means that in 1 hour they would fill...
[tex]\frac{1}{9} +\frac{1}{6} = \frac{5}{18}[/tex] of the pool in 1 hour.
Now to find how many hours it will take divide the pool by the speed with which it is getting filled.
[tex]1 / \frac{5}{18} = 3.6[/tex] hours
3.6 hours in other words is 3 hours and 36 minutes.
A mug is 1/8 full. The mug contains 1/6 of a cup of water. Find the capacity of the mug. Write the answer as a fration or mixed number
Answer:
The capacity of the mug = [tex]1\frac{1}{3}[/tex] cups
Step-by-step explanation:
Given - A mug is 1/8 full. The mug contains 1/6 of a cup of water.
To find - Find the capacity of the mug. Write the answer as a fraction or mixed number
Proof -
Let the capacity of water = x
Given that,
A mug is [tex]\frac{1}{8}[/tex] full of water
⇒Total cups of water in the mug = [tex]\frac{1}{8} x[/tex]
Now,
Given that, The mug contains [tex]\frac{1}{6}[/tex] of a cup of water.
∴ we get
[tex]\frac{1}{8} x[/tex] = [tex]\frac{1}{6}[/tex]
⇒x = [tex]\frac{1}{6}[/tex] × 8
= [tex]\frac{8}{6}[/tex]
= [tex]\frac{4}{3}[/tex] = [tex]1\frac{1}{3}[/tex]
⇒x = [tex]1\frac{1}{3}[/tex]
∴ we get
The capacity of the mug = [tex]1\frac{1}{3}[/tex] cups
