Cdef maps to jklm with the transformation (x,y) to (4x,4y) to (x-4,y-9). What is the value of ef/lm.
Answer:
EF / LM = 1 / 4
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, dilation and rotation.
Dilation is the enlargement or reduction in the size of a figure. If a point A(x, y) is dilated by a scale factor of k, the new point is at A'(kx, ky).
Translation is the movement of a point right, left, up or down. If a point A(x, y) is translated a units left and b units down, the new point is at A'(x - a, y - b).
Translation preserves the size and shape of an object. Dilation preserves the shape but not the size.
Cdef maps to jklm with the transformation (x,y) to (4x,4y) to (x-4,y-9).
CDEF was first dilated by a scale factor of 4 to get (4x,4y) before it was translated by (x-4,y-9). Since dilation changes the size of the figure, hence JKLM would be 4 times the size of CDEF. Therefore:
LM / EF = 4
EF / LM = 1 / 4

Can anyone help???
Answer:
76
Step-by-step explanation:
A full triangle is 180 *always remember
180-153=27
so r is 27
180-77-27=76
or you could do
77+27+x=180
104+x=180
x=180-104

if thrice my age 6 years ago be subtracted from twice my present age the result is present age then my present age is what
Answer:
9 years
Step-by-step explanation:
Let the present age = x
Age 6 years ago = x - 6
Thrice my age 6 years ago = 3*(x -6) =3x - 3*6 = 3x - 18
Twice my present age = 2 *x = 2x
Thrice my age 6 years ago be subtracted from
twice my present age = 2x - (3x - 18)
2x - (3x - 18) = x
2x - 3x + 18 = x
-x + 18 = x {Add x to both sides}
18 = x + x
18 = 2x {Divide both sides by 2}
18/2 = x
x = 9 years

13x = 2(5x+3) solve for x
Answer:
13x=2(5x+3)
13x=10x+6
13x-10x=6
3x=6
x= 6/3
x=2
Answer:
x=2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
13x=2(5x+3)
13x=(2)(5x)+(2)(3)(Distribute)
13x=10x+6
Step 2: Subtract 10x from both sides.
13x−10x=10x+6−10x
3x=6
Step 3: Divide both sides by 3.
3x/3=6/3

-9(2.7 - 1.55) + 3
Answer:
-7.35
Step-by-step explanation:
distribute -9 to 2.7 and 1.55
-9x2.7=-24.3
-9x1.55=-13.95
then subtract -13.95 from -24.3
-24.3-(13.95)=-10.35
Then add 3 to -10.35
Answer = -7.35
Answer:
what is the question I do not know but ill try my best
Step-by-step explanation:
-9(2.7 - 1.55) + 3= -7.35
Drag numbers to write an equation for the line in slope-intercept form. Numbers may be used once, more than once, or not at all.
Graph of a diagonal line with x-axis and y-axis. A line is passing through co-ordinates (0,5) and (2,-3).
Answer:
y = -4x + 5
Step-by-step explanation:
Here, we want to get the equation of the line that passes through the given points
The general form is;
y = mx + b
where m is the slope and b is the y intercept
To find the slope, we use the slope formula
this is ;
m = (y2-y1)/(x2-x1)
(x1,y1) = (0,5)
(x2,y2) = (2,-3)
m = (-3-5)/(2-0) = -8/2 = -4
To get the y-intercept we simply substitute one of the points
But we know that the y-intercept is the y-value when x = 0
From the point we can see (0,5) which means that the y-intercept is 5
so the equation of the line is;
y = -4x + 5
The equation of the graph in slope intercept form is y = -4x + 5
Using slope intercept equation
y = mx + b
where
m = slope
b = y- intercept
Therefore,
Let's take 2 coordinates to get the slope.
(1, 1)(0, 5)
y-intercept = 5
Therefore,
m = 5 - 1 / 0 - 1 = - 4
y = -4x + 5

Answer:
x= 23 y=88
Step-by-step explanation:
3x+23= 4x
x=23
x and y are supplementary angles so they add up to 180 so then if x is 23
23 x 4= 92
so 180-92 is 88
therefore y is 88 and x is 23

sarah lost her science book her school charges a lost book fee equal to 75% of the cost of the book sarah recieved a notice she owes the school $60 for the book how much did the school pay for the book
Answer: $80
Step-by-step explanation:
You have been told that Sarah ended up paying $60, and you were told before that the charge for a lost book was 75%.
Therefore
$60 = 75%
Now we have to find out what amount of money would be equivalent to 100%:
To do this, find out what amount of money would be equivalent to 25% first.
You can do this by dividing both values by 3.
60 / 3 = 20
75 / 3 = 25
So now $20 = 25%
Now find 100% (which is the original amount) multiply each value by 4 :
$80 = 100%
So the school payed $80 for the book.
hope this helps :)

Joseph has a collection of stickers. When the stickers are aranged in piles of 3, there are 2 stickers left over. When the stickers are aranged in piles of 4, there are 2 stickers left over. When the stickers are arranged in piles of 12, how many stickers are left over?
Answer:
2 stickers will be left over
Step-by-step explanation:
To answer the question, all you need to do is figure out at what value of stickers would the remaining stickers be equal to 2 if the piles are made up of either 3 to a set or 4 to a set. To do this, we need to figure out the size of the whole set of stickers.
Lets assume that the total number of stickers is 14. Lets test the 2 given conditions. If we divide it in piles of 3 then we will have a pile of 12 stickers (4 piles of 3 stickers each) with 2 stickers remaining.
Lets test the second condition. If we divide it in piles of 4, we will again have 12 stickers (3 piles of 4 stickers each) with 2 stickers remaining.
Now that both conditions have been satisfied, all we have to do is see how many stickers are left if we make a pile of 12 stickers. In this case, we will have just one pile of 12 stickers and, again, we will be left with 2 stickers.
Therefore, the answer is 2 stickers

domain and range, please help and explain this to me Jim, thanks!!!
Answers:
Domain = {-24, -6, -4, 4, 21, 47}
Range = {24, 55, 45, 77, 3, 93}
Don't forget about the curly braces.
The domain is the set of all allowed x inputs. So we simply list all the x coordinates of the points given. That's all there is to it. The range is the list of all possible y output values, so we just list the y coordinates. Toss out any duplicate y values. Sorting each set is optional because order doesn't matter in a set.
maria draws one marble from a bag containing 5 red, 3 green, and 4 yellow. the probability she draws a yellow marble is____
Answer:
33% or 4/12
Step-by-step explanation:
There are 5 red, 3 green, and 4 yellow, so make it into a fraction. In total there are 12 marbles(5+3+4). There are 4 yellow marbles, so the fraction would be 4/12. Turn this into a percent to get the probability. 4/12 = 0.33 = 33%

2v + 18 = 16 - 4(v + 7)
please help, thank you
Answer:
v=−5
Step-by-step explanation:
2v + 18 = 16 - 4(v + 7)
2v+18=16−4(v+7)
2v+18=16+(−4)(v)+(−4)(7)(Distribute)
2v+18=16+−4v+−28
2v+18=(−4v)+(16+−28)(Combine Like Terms)
2v+18=−4v+−12
2v+18=−4v−12
Add 4v to both sides.
2v+18+4v=−4v−12+4v
6v+18=−12
Subtract 18 from both sides.
6v+18−18=−12−18
6v=−30
Divide both sides by 6.
6v /6 = −30 /6
v=−5
A car loses 20% of its value every
year. How much will a £6000 car be worth after
a)1 year?
b) 3 years?
c) 8 years?
Answer:
See below
Step-by-step explanation:
20% loss a year with initial value of £6000 can be shown as function:
V(t) = 6000*0.8^tV(t) - is the value after t years
a) t = 1 year
V(1) = 6000*0.8 = £4800b) t = 3 years
V(3) = 6000*0.8^3 = £3072c) t = 8 years
V(8) = 6000*0.8^8 = £1006.63What is the slope? (IXL)
