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]
A submarine was in a resting position 400 m below sea level. It rose 225 m. Determine its new depth?
Answer:
175 meters, since its below sea level it would be- -400m - (-225m), subtracting with negative # and negative # is the equivalent of getting closer to zero, just figure out 400 - 225, and put a - symbol at the beginning of the number

Figure ABCD is a rectangle. In rectangles, opposite sides are equal. In the figure, BC and AD are opposite of each other, therefore their side lengths are equal. The side lengths are given: BC=9x-6, and AD=3x+12. Write this as an equation:
9x-6=3x+129x-3x-6=3x-3x+12 (Subtract 3x from each side of the equation)6x-6=12 6x-6+6=12+6 (Add 6 to each side of the equation)6x=18x=3 (Divide each side by 6)please let me know if this is wrong, hope it helps :)

Part 1: What is the rate of rice to quarts of water for this recipe that uses 4 pounds of rice and 5 quarts of boiling water?
Given:
A recipe uses 4 pounds of rice and 5 quarts of boiling water.
To find:
The rate of rice to quarts of water for this recipe.
Solution:
We need to divide the amount of rice by amount of water to get the rate of rice to quarts of water for this recipe.
[tex]\text{Required rate}=\dfrac{\text{Rice in pounds}}{\text{Water in quarts}}[/tex]
[tex]\text{Required rate}=\dfrac{4}{5}[/tex]
[tex]\text{Required rate}=0.8[/tex]
Therefore, the rate of rice to quarts of water for this recipe is 0.8.

y = x - 4. 2x + 3y = -17 substitution method
Answer:
x = -1
y = -5
Step-by-step explanation:
y = x - 4 y = x - 4
2x + 3y = -17 y = (-1) - 4
2x + 3(x - 4) = -17 y = -1 - 4
2x + 3x - 12 = -17 y = -5
5x - 12 = -17
5x - 12 + 12 = -17 + 12 Check
5x = -5 2x + 3y = -17
5x/5 = -5/5 2(-1) + 3(-5) = -17
x = -1 -2 + -15 = -17
-17 = -17
i need to know which one is an expression, equation, and inequality
Answer/Step-by-step explanation:
An expression is a series of number without any signs so expression would be the first one.
Inequality would be when they do a sign like > or <, etc. so it would be the 2nd one.
Equation would be when they have an equal sign which would be the 3rd one.
Simple Ex.
Expression : 2 + 66 / 11 - 3 x 2
Inequality : g + h > f
Expression : 4j - 3 = j

Annalisa is ordering a sandwich. What are the possible independent variables involved in the cost of a sandwich?
Answer:
Step-by-step explanation:
Independent variables may be referred to as one or more single or standalone variables which affects the outcome or output variable, which is the dependent or response variable. To determine the cost of sandwich (this will be the response variable), this will be affected or dictated by the independent variables, which includes ; the size of sandwich, the type of bread roll used (hard roll, soft bun, hero, slice bread). Also, the tyoe of sandwich filling which may be (cheese, Ham salad, Ham and cheese, Egg mayonnaise and so on). Therefore, these variables are independent and the combination of each of these predictor variables will dictate the dependent variable, Cost.

what is the value of x?
Answer:
36
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
72° and 3x are adjacent angles and are supplementary , that is
72° + 3x = 180° ( subtract 72° from both sides )
3x = 108° ( divide both sides by 3 )
x = 36° → C
The triangles below are similar.
10
y
22
33
12
y = [?]
Answer:
y=15
Step-by-step explanation:
Since the triangles are similar you take 22/33 and 10/y then cross multiply and get 330=22y now divide 330 by 22 and you get 15
The value of x is 26.4 unit and y is 15 units,
What is Similarity?Two triangles are said to be comparable if their two sides are in the same ratio as the two sides of another triangle and their two sides' angles inscribed in both triangles are equal.
Given:
As, the two triangles are similar then the ratio of their corresponding sides and angles are equal.
So, 22/ 10 = 33/ y
22y = 330
y = 330/22
y = 15
and, 22/10 = x/ 12
264 = 10 x
x= 26.4
Hence, the value of x is 26.4 unit and y is 15 units,
