Map quadrilateral ABCD to quadrilateral A′B′C′D′ with a rotation of 180° about the origin followed by a translation 3 units left and 7 units up.
Answer:
See Explanation
Step-by-step explanation:
Given
Shape: Quadrilateral ABCD
Transformations:
180 degrees rotation
3 units left
7 units up
Required
Determine A′B′C′D
The coordinates of ABCD is not given; So, I will solve generally.
Assume the coordinates of ABCD is (x,y)
When (x,y) is rotated 180 degrees, the new point is: (-x, -y)
Solving further:
Translation 3 units left
When a point (x,y) is translated b units left, the new point is (x - b, y).
So:
[tex](-x, -y) ====> (-x - 3, -y)[/tex]
Translation 7 units up
When a point (x,y) is translated h units up, the new point is (x, y + b).
So:
[tex](-x - 3, -y) ====> (-x - 3, -y + 7)[/tex]
Assume that the coordinates of A in ABCD before translation is (2,6).
i.e. A = (2,6)
The image A' will be:
[tex]A' = (-2-3,-6+7)[/tex]
[tex]A' = (-5,1)[/tex]

Video club A charges $10 for membership and. $4 per movie rental. Video club B charges $15 for membership and $3 per movie rental. For how many rentals will be cost be the same at both video clubs? What is that cost?
Answer:
5 rentals for $30
Step-by-step explanation: *using y = mx + b*
Info Given:
Video Club A-
$10 (would be your b)
$4 (would be your x)
Video Club B-
$15 (would be your b)
$3 (would be your x)
HOW TO SOLVE:
Video Club A - y = 4x + 10
Video Club B - y = 3x + 15
Set them equal to eachother to solve for x!
4x + 10 = 3x + 15
- 10 - 10
4x = 3x + 5
-3x -3x
x = 5 rentals
Plug in the x into both or just one equation to find the price!
y = 4x + 10
= 4(5) + 10
= 20 + 10
y = $30

State true or false. If 9 is the solution of variable x in the equation fraction numerator 5 straight x space minus space 7 space over denominator 2 end fraction space equals space straight y, then the value of y is 28
Answer:
False
Step-by-step explanation:
Based on what is stated in the question :
Expressing the worded equation Mathematically,
(5x - 7) / 2 = y
If y = 28
(5x - 7) / 2 = 28
Cross multiply
5x - 7 = 28 * 2
5x - 7 = 56
5x = 56 + 7
5x = 63
x = 63 / 5
x = 12.6
Hence, x ≠ 9

A boat travelled 336 km downstream with the current. The trip downstream took 12 hours.
a) Come up with an equation to describe this relationship
b) If the current is moving at 2 km/h, how fast is the boat moving from its engine?
Answer:
When travelling downstream, the speed of the boat and the current add up.
Let the speed of the boat is b and the speed of the current is c.
Use distance formula:
d = st, d-distance, s- speed, t- timea)
Then we have equation:
12(b + c) = 336b)
If c = 2, then the equation is:
12(b + 2) = 336b + 2 = 28b = 26 km/hWrite the solution to the given inequality in interval notation

The ratio of green bags to white bags in the store is equal to 2 to 5.There are 30 white bags in the store how many green bags are there?
Answer:
12 green bags
Step-by-step explanation:
Given data
The given ratio of green bags to white bags is
=2 to 5
=2:5
Number of white bags=30
Applying the part to part method, let the number of green bags be x
so
2/5=x/30
cross multiply
30*2=5x
60=5x
divide both sides by 5
x= 60/5
x=12
Hence there are 12 green bags

Angle x is 35 degrees less than angle y,angle z is a right angle ,How much is angle x and angle y?
Answer:
∠y = 62.5°
∠x = 27.5°
Step-by-step explanation:
z is right angle. ∠z = 90°
∠x = ∠y - 35
∠x + ∠y + ∠z = 180 {Angle sum property of triangle}
y - 35 + y + 90 = 180
y + y - 35 + 90 = 180 {Combine like terms}
2y + 55 = 180
2y = 180 -55 {Subtract 55 from both sides}
2y = 125 {Divide both sides by 2}
y = 125 /2
∠y = 62.5°
∠x = 62.5 - 35 = 27.5°

wall.
104
of her toy cars are on the wall, and 74% of her toy cars are in the display
case. What is the total number of toy cars in Serenity's collection?
If 74% are in the display, then 100% - 74% = 26% are hung on the wall.
This means 104 cars is 26% of her collection.
To find the total collection divide the number on the wall by the percentage of the collection:
104/0.26 = 400
The total number of her collection is 400 cars.
