what is the value of X, Z, and Y.
Answer:
x= -64°, y= -63°, z=-57°
Step-by-step explanation:
→Solution,
Here,
60°=(-y-3)°[The opposite sides of a parallelogram are equal]
⇒y= -60°-3°
⇒y= -63°
⇒60°+(-2x-8)°=180°[Sum of co-interior angles is 180°]
⇒52°-2x=180°
⇒52°-180°=2x
⇒x= -128°/2
⇒x= -64°
⇒60°+(-2z+6)°=180°[Sum of co-interior angles is 180°]
⇒66°-2z=180°
⇒66°-180°=2z
⇒z= -114°/2
⇒z= -57°

50 points!! Question 1) Are the corresponding angles in figures ABCD and WXYZ congruent? Yes or No? Question 2) Are the corresponding sides in figures ABCD and WXYZ proportional? Yes or No? Show work for question 2. Question 3) Are figures ABCD and WXYZ similar? Yes or no?
No, there is not a rigid transformation or a combination of rigid transformations that will map ABCD to WXYZ.
What is congruency?The Side-Angle-Side Congruence Theorem (SAS) defines two triangles to be congruent to each other if the included angle and two sides of one are congruent to the included angle and corresponding two sides of the other triangle.
Two figures are congruent if their vertices can be mapped into one another by appropriate rigid transformation or a combination of rigid transformations. Examples of the transformation are; reflection, dilation, rotation and translation.
Comparing the two figures, it would be observed that they are not congruent. Since there is not a rigid transformation or a combination of rigid transformations that will map ABCD to WXYZ.

Jeff can weed the garden twice as fast as his sister Julia. Together they can weed the garden in 3 hours. How long would it take each of them working alone? Which of the following equations could be used to solve this problem?
Answer:
Jeff, 4.5 hours; Julia 9 hours.
Step-by-step explanation:
To solve the problem, we need to write two equations using the given information.
So, writing the first equation we have:
We know that Jeff can weed the garden twice as fas as his sister Julia, so:
Also, from the statement we know that they can weed the garden in 3 hours, so, writing the second equation we have:
Then, we need to substitute the first equation into the second equation in order to isolate Julia's rate, so, solving we have:
We have that Julia could weed the garden by herself in 9 hours.
So, calculating how long will it take to Jeff, we have:
We have that Jeff could weed the same garden by himself in 4.5 hours.

The figure below is rotated 180° clockwise. What are the coordinates of the image of point A after this transformation?
Answer:
(-2, -1)
Step-by-step explanation:
The easiest way to approach this problem is to think of each quadrant as being 90 degrees. As you can see, each quadrant has a 90 degree angle.
If we were to move 2 quadrants (or 180 degrees) clockwise, we would end up in the third quadrant (- , -)
Because we are moving clockwise on the graph, the shape would also turn clockwise. 180 degrees is the halfway point, so the shape will appear to be upside down.
If you're a visual learner, I'd recommend finding a website with an online graph (something like desmos or geogebra) that would allow you to actually graph the points and change their position with commands.
Hope this helps :)

X + 12 : 4
(4+12) = x
Answer:
First option
Step-by-step explanation:
The result of first expression:
7(6+z) multiply 7 with inside the parenthesis
7(6+z) = 42 + 7z
the result of second expression:
since we need to do multiplying first,
7*6 = 42 and 7*z = 7z
then we add them
42 + 7z this is the same result we found for the first equation

Answer:
y = -(x - 2)² - 4
Step-by-step explanation:
The vertex of this function is (2, -4), which is given in the tableThe vertex form an equation is given as :
y = a(x - h)² + kSubstitute the vertexy = a(x - 2)² - 4Substitute any point in the table to find a :
-8 = a(0 - 2)² - 44a = -4a = -1Hence, the final equation :
y = -(x - 2)² - 4Option 21. it has at least 10 values. 2. it has at least 3 values that are different. 3. it has a mean and median of 12.
Answer: 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17
Step-by-step explanation:
First, we can ensure that 12 is the median by putting it in the middle and putting the same amount of numbers to its left and right side. To make the values have a mean of 12, the easy why to do it is to subtrate one as you move to the left and add one as you move to the right, that way they will cancel each other out and keep the mean at 12. The answer has a total of 11 values, has more than 3 values that are different, and has a mean and median of 12.
7+8+9+10+11+12+13+14+15+16+17=132
132/11=12
There are 5 values to each side of 12, making 12 the median.

The value of x in the given equation [ √( 1 + (25/144) ) = 1 + (x/12) ] is 5.
What is an Equation?
An equation is simply a mathematical formula that expresses the equality of two expressions, using the equals sign as a connection between them.
Given that;
√( 1 + (25/144) ) = 1 + (x/12)Find the value of x.First, we square both sides
√( 1 + (25/144) ) = 1 + (x/12)
(√( 1 + (25/144) ))² = (1 + (x/12))²
1 + (25/144) = 1 + ( x²/144)
Collect like terms
1 - 1 + (25/144) = ( x²/144)
25/144 = x²/144
We cross multiply
25 × 144 = x² × 144
Multiply each sides by 1/144
x² = 25
x = √25
x = 5
Therefore, the value of x in the given equation [ √( 1 + (25/144) ) = 1 + (x/12) ] is 5.

Two Truths and a Lie: Remember, the function has a maximum and an axis of symmetry at x = 2. Two of the following functions could represent this scenario while one cannot. Determine which two could represent the scenario and which one cannot. Explain how you know and show all necessary work to support your reasoning. a) f(x) = −x 2 + 4x + 2 b) g(x) = −(x + 2) 2 − 5 c) h(x) = −2(x − 1)(x − 3)
The functions f(x) and h(x) have an axis of symmetry of x = 2 and a maximum
How to determine the function?The functions are given as:
f(x) = -x² + 4x + 2g(x) = -(x + 2)² - 5h(x) = -2(x − 1)(x − 3)A quadratic function can be represented as:
y = ax² + bx + c
y = a(x - h)² + k
In both cases, when a < 0; the function has a maximum.
This means that all three functions have a maximum.
Next, we determine the axis of symmetry:
In y = ax² + bx + c, the axis of symmetry is x = -b/2aIn y = a(x - h)² + k, the axis of symmetry is x = hUsing the above forms, we have:
f(x) = -x² + 4x + 2
Axis of symmetry, x = -4/(2 * -1)
x = 2
g(x) = -(x + 2)² - 5
Axis of symmetry, x = -2
h(x) = -2(x − 1)(x − 3)
Expand
h(x) = -2x² - 8x + 8
Axis of symmetry, x = -8/(2 * -2)
x = 2
This means that f(x) and h(x) have an axis of symmetry of x = 2
Hence, the functions f(x) and h(x) have an axis of symmetry of x = 2 and a maximum
