What is the length of DE
A. 18
B. 12
C. 10
D. 22
Answer:
the length of DE is A) 18
Step-by-step explanation:
these triangles are similar so you need to create a proportion!
since sides DF and FE are the same, it means that AC and CB are the same!
now we have to find the hypotenuse for DE, which is X
- set up a proportion!
side AC/side AB = side DF/side DE ----> 15/27 = 10/x
- butterfly multiply to get 15x = 270
- divide both sides by 15 to isolate x
now you get --------> x = 18!

For each pair of points, find the slope of the line that passes through both points. If you get stuck, try plotting the points on graph paper and drawing the line through them with a ruler. Use fractions, not decimals, and make sure to simplify all fractions.
Answer:
a. 1 1/2 (or 3/2)
b. 2/3
c. 1
d. 1
Step-by-step explanation:
Part A: (1,1) (7,5)
To determine the slope, you will use the equation m=(y2-y1)/(x2-x1). Keep in mind that it doesn't matter what point you use for (x1, y1) or (x2, y2).
Let's plug in the numbers for part a:
m=(7-1)/(5-1)
Let's then solve the problems inside the parentheses:
m=6/4
And finally, we simplify:
m=3/2 (or 1 1/2 depending on what your teacher wants for an answer)
For these others, I will just go through the steps and not explain them, if you need help or don't understand something I'm doing, either look back at what I did for part a or comment on this answer.
Part B: (1,1) (5,7)
m=(5-1)/(7-1)
m=(4/6)
m=2/3
Part C: (2,5) (-1,2)
m=(-1-2)/(2-5)
m=(-3/-3)
m=1
Part D: (2,5) (-7,-4)
m=(-7-2)/(-4-5)
m=(-9/-9)
m=1
The value of y is directly proportional to the value of x.
If y = 10 when x = 5, what is the value of the following.
a) find the value of y when x is equal to 4.
b) find the value of x when y is equal to 6
Answer:
a) find the value of y when x is equal to 4.
Step-by-step explanation:
Answer:
a) the value of y will be x=5 - 4= 1
therefore y=1
b) the value of x will be y= 10 - 6= 4
therefore x=4

Step-by-step explanation:
Write an equation of the parabola in intercept form (3, 4) (4,0) (2,0)
An equation of the parabola is y=?
The equation of the parabola is gotten as;
y = -4x² + 24x - 32
We are given the coordinates of a parabola to be;
(3, 4) ; (4,0) ; (2,0)
The general form of equation of a parabola is given by;
y = ax² + bx + c
Let's plug in the x and y coordinates as given to us from the question.
For coordinate (3, 4), the equation is;(3²)a + 3b + c = 4
9a + 3b + c = 4 ----(eq 1)
For coordinate (4, 0), the equation is;(4²)a + 4b + c = 0
16a + 4b + c = 0 ----(eq 2)
For coordinate (2, 0), the equation is;(2²)a + 2b + c = 0
4a + 2b + c = 0 ----(eq 3)
Solving the 3 equations using an online simultaneous equation solver tool, we have; a = -4; b = 24; c = -32Plugging these values of a, b and c into the general equation of parabola gives us;y = -4x² + 24x - 32

7v- 5 ≥ 65 or -3v - 2 ≥ -2
The result if the inequality expressions are v ≥ 10 and v < 0
Given the following inequality expression
7v- 5 ≥ 65 or -3v - 2 ≥ -2
Solve the inequality individually
7v - 5 ≥ 65
Add 5 to both sides
7v - 5 + 5 ≥ 65 +5
7v ≥ 70
v ≥ 70/7
v ≥ 10
For the inequality-3v - 2 ≥ -2
Add 2 to both sides
-3v - 2 + 2≥ -2 + 2
-3v ≥ 0
v < 0
Hence the result if the inequality expressions are v ≥ 10 and v < 0

The curve above the graph of a sinusoidal function. It goes through the points (-11,0) and (3,0). Find a sinusoidal function that matches the given graph.if needed you can enter pi=3.1416… as pi in your answer otherwise use at least 3 decimal digits.
F(x)=
Considering the zeros, the graph for the sinusoidal function is:
[tex]F(x) = \sin{\frac{\pi}{7}(x-3)}[/tex]
The zeros given for the function are: [tex]x = -11, x = 3[/tex].For practicality, we are going to define a sine function, which has a zero at x = 0, so we use shifting.The sine function is given by:
[tex]F(x) = A\sin{Bx}[/tex]
In which:
The amplitude is A.The period is [tex]T = \frac{2\pi}{B}[/tex].In this problem:
We suppose an amplitude of 1, thus [tex]A = 1[/tex].The difference between the zeros is 14, so we use a period of 14, thus [tex]T = 14[/tex], and:[tex]\frac{2\pi}{B} = 14[/tex]
[tex]B = \frac{2\pi}{14}[/tex]
[tex]B = \frac{\pi}{7}[/tex]
Thus:
[tex]F(x) = \sin{\frac{\pi}{7}x}[/tex]
Like this, the zeros are at [tex]x = -14[/tex] and [tex]x = 0[/tex]. We want it at [tex]x = -11, x = 3[/tex], thus, we shift the function 3 units to the right, that is, the function is:
[tex]F(x) = \sin{\frac{\pi}{7}(x-3)}[/tex]
The graph is sketched at the end of this answer, and has the desired behavior, which are points (-11,0) and (3,0).

Graph the image of the given triangle after a rotation of 180° about the origin
Answer:
The bottom point is at (-1, 1) the right point is at (6,-2) and the left point is at (-5,4)
Step-by-step explanation:
Rotation of any polygon about the origin gives the opposite sign coordinate of the original figure thus new coordinate will be (1,-1),(2,-6), and (5,-4).
What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
Reflection is a mirror image of a graph about any axis.
If a coordinate of any polygon (x,y) is rotated 180 degrees about the origin either clockwise or anticlockwise then its coordinate will change sign.
(x,y) → (-x,-y)
Given triangle have coordinates as (-1,1),(-2,6), and (-5,4).
The transformation (x,y) → (-x,-y) gives ;
(-1,1) → (1,-1)
(-2,6) → (2,-6)
(-5,4) → (5,-4)
Hence "Rotation of any polygon about the origin gives the opposite sign coordinate of the original figure thus new coordinate will be (1,-1),(2,-6), and (5,-4)".

what is 5x(2x+7)+x(3x-5 do you know
Answer:
43xx
Step-by-step explanation:
5x(2x+7)+x(3x-5)
first, do the equations inside the parentheses
2x+7=9x
3x-5=-2x
so,
5x(9x)+x(-2x)
Next, do 5x times 9x
(5x) x (9x) = 45
so,
45+x(-2x)
Next, do x times (-2x)
(x) x (-2x)=-2xx

How to solve linear equation
You can use elimination and substitution method
EXAMPLE :
Given :
2x + y = 5
3x - 5y = 1
2x + y = 5 (× -5)
3x - 5y = 1
__________
-10x - 5y = - 25
3x - 5y = 1
____________ _ (elimination)
-13x = - 26
x = - 26/-13
x = 2
Substitution x = 2 to 2x + y = 5 :
2x + y = 5
2(2) + y = 5
4 + y = 5
y = 5 - 4
y = 1
1.Azad has $500 and wants to go on a holiday, but does not have sufficient money. He decides to save $40 per week for a number of weeks to make up the deficit.
How much will he have saved at the end of the 5th week? Explain your answer.
2.A baker has 400kg of flour on the first day of the month and uses no flour that day. How much will he have at closing time on the 17th day of the month, if he uses 24 kg each day after that?
1. At the end of the 5th week he would have saved a total of $700
2. The amount of flour he would have at the closing time on 17th of the month will be 16kg
1.
Azad amount = $500
He wants to go on a holiday but he lacks sufficient money. This means the $500 in his possession is not enough.
He decided to save $40 dollars per week for a number of weeks to make up the deposits.
let
w = number of weeks
Therefore, his saving for any number of weeks will be
40wThe amount he would have saved for 5 weeks will be
40×5=$200
The total amount in his possession at the end of the fifth week will be 200 + 500 = $700
2.
The baker has 400 kg of flour. The first day of the month he didn't use any flour. This means on the first day of that month the flour was still 400 kg. The amount he has on the 17th day of the month can be calculated below.
The 17th day simply implies he used the flour for 16 days, the first day of the month he didn't use anything. He uses 24 kg for each day. Therefore the amount he uses for 16 days will be
16×24=384 kgThe amount he has at the closing time of 17 days of the month will be

A washing machine is on clearance for 30% off. If the sale price of the washing machine is $395.49, what was the original price? Round to the nearest cent if necessary. Justify your solution.
Answer:
Discount = Original Price x Discount %/100
Discount = 395.49 × 30/100
Discount = 395.49 x 0.3
You save = £118.65
Final Price = Original Price - Discount
Final Price = 395.49 - 118.647
Final Price = £276.84. (ANSWER)
original price of washing machine is $564.99 if the sale price of the washing machine is $395.49 with 30% off.
What is Percentage?Percentage is defined as a given part or amount in every hundred
Based on the given conditions, formulate:
x×(1-30%)=395.49
Apply multiplicative distribution
x-0.3x=395.49
Combine the like terms
0.7x=395.49
x=395.49/0.7
Convert decimal to fractions
x=(39549/100)/(7/10)
x=39549/(10×7)
x=39549/70
x=564.99
Hence original price of washing machine is $564.99
