Line segment RS has endpoints R (-2, 4) and S (-4, -1).
Line segment R''S'' has endpoints R'' (3, -3) and S'' (5, 2).
Name the transformation that maps line segment RS to line segment R''S''.
Answers
Answer:
rotation 180° (ccw) over point (0.5 , 0.5)
Step-by-step explanation:
R (-2, 4) , S (-4, -1) -> R'' (3, -3) , S'' (5, 2)
check: rotation over (0.5,0.5) 180°
x'' = - (x - x₀) + x₀ .. x: original x coordinate, x₀ : center of rotation
y" = - (y - y₀) + y₀
for R" : x" = - (-2 - 0.5) + 0.5 = 3
y" = -(4 - 0.5) + 0.5 = -3
You can verify the coordinates of S" by the above formula.
** (0.5,0.5) is the intersect of RR" and SS"

Calculate the value of x and state the geometric relationship
Answers
So, 6x+12+4x+18=180
Combine like terms:
10x+30=180
Subtract 30 from both sides:
10x=150
Divide both sides by 10:
x=15.
Therefore, the angles are same-side interior angles and x=15.

Mark me as brainliest please.
Step-by-step explanation:
The total cost of Beena's travel, villa and art lessons = £1790.97
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, we have,
The total cost of her travel is £349
Beena is on holiday for 2 weeks.
The cost of the villa is 650 euros per week.
i.e. 2*650
=1300 euros
=1300/1.12
=£1160.71
While on holiday, Beena has 7 art lessons.
The cost of each art lesson is 45 euros.
i.e. total cost = 7*45
=315
=315/1.12
=£281.25
[Using an exchange rate of 1.12 euros = £1]
Hence, The total cost of Beena's travel, villa and art lessons = £1790.97

What is the equation of the line that passes through the point (-6, -7) and has a slope of 0
Answers
Answer:
x = - 6
Step-by-step explanation:
A line with a slope of zero is a horizontal line parallel to the x- axis with equation
x = c ( where c is the value of the x- coordinates the line passes through )
The line passes through (- 6, - 7 ) with x- coordinate - 6 , then
x = - 6 ← equation of line

What is the value of x in the equation 3(2x + 8) = 0? (4 points) Group of answer choices −8 −4 4 8
Answers
Answer:
-4
Step-by-step explanation:
Start with 3(2x + 8) = 0.
Distribute the 3 to the 2x and 8 in the parentheses.
That will give you 6x + 24 = 0.
Subtract 24 from both sides, which will get x by itself and leave you with 6x = -24.
Divide both sides by 6 to get x = -4.
That is your answer.
Hope this helped.
3(2x) = 6x
3(8) = 24
6x + 24 = 0
24-24
0-24
6x = -24

Answer:
B) $1.25
Step-by-step explanation:
1. First, let's take two points. In this case, we're going to take (4,5) and (8,10). We took 2 points, so we can verify the unit rate/cost per pound of pineapple.
2. To find the cost per pound of pineapple, we have to divide the cost (the y-coordinates) by the pound (x-coordinates)
5 ÷ 4 = 1.2510 ÷ 8 = 1.253. Now, since we can verify with 2 coordinates that the cost per pound is $1.25, the answer is B) $1.25.

Transpose for p

Make h the subject
m = r - h + 4d
Answers
The result of making the required variable the subject in both equation are :
p = w - cgh = - (m - r - 4d)Making p the subject in w = p + cg :
w = p + cg
Subtract cg from bith sides
w - cg = p + cg - cg
p = w - cg
2.)
Make h the subject m = r - h + 4d
m = r - h + 4d
Subtract r from both sides
m - r = r - h + 4d - r
m - r = - h + 4d
Subtract 4d from both sides
m - r - 4d = - h
Divide both sides by - 1
h = - (m - r - 4d)
