Which transformations can be used to carry ABCD onto itself? The point of
rotation is (3,2). Check all that apply.
Answers
Answer:
A and B
Step-by-step explanation:
For A, y=2 is the axis of vertical symmetry, meaning a reflection would map the shape onto itself.
For B, x=3 is the axis of horizontal symmetry, meaning a reflection would map the shape onto itself.
For C, a rotation of 90 degrees would make the shape taller vertically and shorter horizontally, therefore it would be wrong.
For D, a translation two units down would move all points down, even though some would need to go up, therefore it would be wrong.

Select the correct solution for the expression. 2/5 + 3/8 A. 2/5 + 3/8 = 5/13 B. 16/40 + 15/40 = 31/40 C. 10/40 + 24/40 = 34/40 D. 2/5 + 3/8 = 6/40
Answers
Answer:
B
Step-by-step explanation:
To add 2/5 and 3/8, we need to find a common denominator for the two fractions.
The smallest multiple of 5 and 8 is 40, so we can use 40 as the common denominator.
Multiplying the numerator and denominator of 2/5 by 8, we get:
2/5 = 16/40
Multiplying the numerator and denominator of 3/8 by 5, we get:
3/8 = 15/40
Now, we can add the two fractions:
2/5 + 3/8 = 16/40 + 15/40
Simplifying the numerator, we get:
2/5 + 3/8 = 31/40
Therefore, 2/5 + 3/8 is equal to 31/40.

Answers
Answer:
D. 110
Step-by-step explanation:
30+40=70
180-70=110
Answer:
∠CEF = 110°
Step-by-step explanation:
ΔBED ,
∠BED + ∠BDE + ∠DBE = 180 {Angle sum property}
∠BED + 40 + 30 = 180
∠BED + 70 = 180
∠BED = 180 -70
∠BED = 110°
∠CEF = ∠BED {Vertically opposite angles}
∠CEF = 110°

Answers
Answer:
Andre should stop at (-3 , 6.5)
Step-by-step explanation:
The change in x is from -15 to 25 which is 40 units. 40 x 3/10 = 12 which means Andre moves 12 units right starting from -15 so the x coordinate is -15+12 = -3
The change in y is from 2 to 17 which is 15 units. 15 x 3/10 = 4.5 which means Andre moves 4.5 units up starting from 2 so the y coordinate is 2+4.5 = 6.5.

What is the missing side length?
(Use Pythagorean Theorem)
Answers
Answer:
20 units
Step-by-step explanation:
The Pythagorean Theorem states that:
\(a^{2} + b^{2} = c^{2} \\\)
Now we can insert values into the equation.
\(a = 15\\b = b\\c = 25\\\)
Now we can plug these ☝ values into the Pythagorean Theorem:
\(15^{2} + b^{2} = 25^{2}\\\)
After we solve for \(b\) we get:
\(b^{2} = 400\\b = 20\)
Answer:
b = 20
Step-by-step explanation:
15 + b = 25
(you have to square each one)
15 x 15 = 225
b x b = b
25 x 25 = 625
625 - 225 = 400
\(\sqrt{400}\) = 20

The table to represent a linear function with a rate of change of +5

What is linear function?The slope-intercept pattern of the linear function equation. As a result, it is written as f(x) = mx + b, where m denotes the slope and b the line's y-intercept.
The graph in the table shows a linear function.
The linear function's general equation is written as y = ax+b, where a is the slope and b is a constant.
Finding the linear function's equation by using the first and third points from the table
at x = 3 ⇒ y = 13 and at x = 5 ⇒ y = 23
13 = 3a+b → (1)
23 = 5a+b → (2)
solve (1) and (2) to find a and b
So, a = 5 and b = -2
∴ y = 5x - 2
After that by substitution with x = 4 int the equation of y
∴ y = 5*4-2 = 18
m= 18
Thus, option C is correct.

The only numbers that can have 2 digits and two of which equal to five can only be:
3+2
2+3
4+1
1+4
So the numbers are: 41,14,23, and 32.
41-9=32
14-9=5
23-9=14
32-9=23
Since the question is asking for the number who’s difference is the reverse of one of the numbers. The only possible answer is 32 because 32-9= 23. (23 is the reverse of 32)
3+2 is equal to 5
32 - 9 is equal to 23 witch is the reverse of 32

The two angles with the variable x form a linear pair and therefore:
16x - 18 + 10x + 3 = 18026x - 15 = 18026x = 195x = 195/26x = 7.5Angles 16x - 18 and 12y are congruent as vertical angles:
16*7.5 - 18 = 12y102 = 12yy = 102/12y = 8.5Answer:
x = 7.5
y = 8.5
Step-by-step explanation:
Linear Pair
Two adjacent angles that sum to 180° (two angles which when combined together form a straight line).
To find x, equate the sum of the two angles with the variable x to 180° and solve:
⇒ (16x - 18)° + (10x + 3)° = 180°
⇒ 16x - 18 + 10x + 3 = 180
⇒ 26x - 15 = 180
⇒ 26x = 195
⇒ x = 7.5
Vertical Angles Theorem
When two straight lines intersect, the opposite vertical angles are congruent.
Therefore:
⇒ (16x - 18)° = 12y°
Substitute the found value of x into the equation and solve for y:
⇒ 16x - 18 = 12y
⇒ 16(7.5) - 18 = 12y
⇒ 120 - 18 = 12y
⇒ 102 = 12y
⇒ y = 8.5
