In the similarity
transformation of AABC
to ADFE, AABC was dilated by
a scale factor of [? ], reflected
across the [ ], and moved
through the translaton [ ].
B. 1/2
D. 1/3
Answers
Answer: A
Step-by-step explanation:
Following the first two steps of the sequence of transformations,
[tex]A(-4,-2) \longrightarrow (-2,-1) \longrightarrow (-2,1)[/tex]
We need to map this onto D(1,1), which involves a translation 3 units right.
In the similarity transformation of ΔABC to ΔDFE, ΔABC was dilated by a scale factor of [1/2 ], reflected across the [x-axis ], and moved through the translation [(X+3, Y+0)].
So, correct option is: A.
Here, we have,
from the given fugre we get,
A =( -4, -2)
Following the first two steps of the sequence of transformations,
Dilated by a factor of 1/2 => A' = ( -2, -1)
reflected across the X-axis => A''=( -2, 1)
and moved through the translation becomes D = ( 1,1)
We need to map this onto D(1,1), which involves a translation 3 units right.
so, translation=> ( -2 + 3, 1+0) => (X+3, Y+0)

For Marvin used the Quantitative Reasoning Process to build a budget while he is going to college.

Marvin will receive a scholarship each semester for $958.35 money can Marvin spend each month, on average, for things like groceries, entertainment, and miscellaneous items is mathematically given as
$4512.6
How much money can Marvin spend each month, on average, for things like groceries, entertainment, and miscellaneous items?Savings with Marvin = $2,595.9
Scholarship amount = $958.35
Total Scholarship amount received in 2 semesters = $958.35 X 2 = $ 1916.7
Now total money that Paolo have = (Savings with Marvin) + (Total Scholarship amount received in both semesters) = $2,595.9 + $1916.7 = $ 4512.6
Tuition & books cost = $2000
Tuition & books cost for 2 semesters = $2000 X 2 = $4000
Housing cost for 2 semester contract =$1,000
Total expenses in books and housing = $4000+ $1000 = $5000
Money left with Marvin after Total expenses in books and housing = $ 4512.6 - $5000 = −487.4
This means he has overspent.

Answers
Answer:
231,000
Step-by-step explanation:
In the ratio of 11:13, if you plug in 13, the corresponding value is 11.
Dividing 11 by 13 shows that if you also multiply 13 by 0.846 (Rounded) it also equals 11.
So multiplying 0.846 by the original price of 273,000, we get 231,000.
The new selling price of the car will be 231,000. Then the correct option is A.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

To solve this exercise, we apply the rule of three:
Oranges......................Price
8.................................$4.40
9.......................................x
We solve as follows:
[tex]\boldsymbol{\sf{x=\dfrac{9\times4.40}{8}=\dfrac{39.6 }{8}=4.9 }}[/tex]
Therefore, 9 oranges would cost $4.9.
{ Pisces04 }The required cost of the amount of 4.95 dollars would be for 9 oranges.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
We have been given that a grocery store sells a bag of 8 oranges for $4.40.
We have to determine the cost for 9 oranges.
Let's assume x dollars would it cost for 9 oranges.
As per the given condition, we can write the ratio as:
8 oranges : $4.40 = 9 oranges : x dollars
⇒ 8 / 4.40 = 9 / x
Cross multiplication and rearrange the terms of the above equation,
⇒ 8x = 4.40×9
Divide by 8 into both sides of the equation,
⇒ x = (4.40×9)/8
⇒ x = (39.6)/8
⇒ x = 4.95
Therefore, the cost of the amount of 4.95 dollars would for 9 oranges.

Answer:

Step-by-step explanation:
Equations that are parallel have the same slope
y = 6x+7 is written in slope intercept form where the slope is 6 and the y intercept is 7
The lines will have a slope of 6
The point (0,9) is the y intercept because the x value is 0
We can write the equation in slope intercept form y = mx+b
y = 6x+9
Answer:
Hello! The answer is y = 6x + 9.
Step-by-step explanation:
When lines are parallel, they will have the same slope but a different y-intercept.
The y-intercept, in this case, would be (0, 9) since the x-coordinate equals 0. This leaves us with 9 as the y-intercept.
Our slope-intercept form equation will be written as:
