Reflect over the line y = x
Answer:
After the reflection over the line y=x, the image points are:
A'(-1, -2) B'(3, -1) C'(2, -3)Step-by-step explanation:
We know that when a point is reflected cross the line y = x, the x-coordinate, and y-coordinate change places.
i.e.
The reflection of the point (x,y) across the line y = x is the point (y, x).Given
A(-2, -1)B(-1, 3)C(-3, 2)so after the points reflected cross the line y = x
P(x, y) → P'(y, x)
A(-2, -1) → A'(-1, -2)
B(-1, 3) → B'(3, -1)
C(-3, 2) → C'(2, -3)
Therefore, after the reflection over the line y=x, the image points are:
A'(-1, -2) B'(3, -1) C'(2, -3)how do i find the value of x in -5 = .5x

The midpoint of AB is M ( 1 , − 3 ). If the coordinates of A A are ( − 6 , − 7 ),what are the coordinates of B?
Answer:
a= -4
b=1
Step-by-step explanation:
Midpoint=(1,-3)=(x,y)
A=(-6,-7)=(x1,y1)
Let ,the coordinates of B be 'a and b' .
So,
B=(a,b)=(x2,y2)
Using ,midpoint formula,
(x,y)=(x1+x2\2 , y1+y2 \2)
or, (1,-3)=(-6+a\2 , -7+b \2)
Now,
Taking the corresponding sides,
or, 1 =-6+a/2
or, 1*2=6+a
or, 2=6+a
or, 2-6=a
a=-4
Then,
-3= -7+b/2
or, -3*2= -7+b
or, -6 =-7+b
or, -6+7=b
b=1

we can describe 3x-2 as an expression.
how can we describe the parts of the expression the arrows point to
Answer:
we can describe the parts of the expression that the arrows
point to 3x-2 such as:
↑(x variable)
[tex]3x-2[/tex] ← (2 constant)
↓
(3 coefficient)
Step-by-step explanation:
Given the expression
[tex]3x-2[/tex]
As we have to describe the parts of the expression the arrowspoint to [tex]3x-2[/tex].
we can describe the parts of the expression that the arrows
point to 3x-2 such as:
↑(x variable)
[tex]3x-2[/tex] ← (2 constant)
↓
(3 coefficient)
Therefore, it is clear that:
The upper arrow '↑' points to the variable part 'x' of expression which is 'x'.The lower arrow '↓' points to the coefficient part of the expression which is '3'.The arrow '←' points to the constant part of the expression which is '2'.PLEASE PLEASE HELP GIVING BRAINALIST AND EXTRA POINTS FOR FIRST PERSON
Answer:
17. x = -2
18. All real numbers
19. No solution
Step-by-step explanation:
17. 10z + 26 = -3z
-10z -10z
26 = -13z
Divide both sides by -13
-2 = x
18. 4(3x - 5) = 2(6x - 10)
Distribute the 4
12x - 20 = 2(6x - 10)
Distribute the 2
12x - 20 = 12x - 20
Both sides are equal
All real numbers

Given △ACP ≅ △LNX, find each missing measure.
9514 1404 393
Answer:
XL = 13 cm, m∠L = 29°
AC = 21 cm, m∠C = 29°
PC = 13 cm, m∠Y = ?? (there is no angle Y in the figure)
Step-by-step explanation:
The figure on the right shows the triangles are isosceles, with XL = XN. That means also PA = PC. Those side lengths are all the same: 13 cm.
PA = PC = XL = XN = 13 cm
In the same fashion, ...
LN = AC = 21 cm
__
Of course, the angles have a similar relationship:
∠A = ∠C = ∠L = ∠N = 29°
The two base angles in the triangle add to 58°, so the third angle is ...
180° -58° = 122°
∠P =∠X = 122°
_____
Additional comment
As is often the case in over-specified problems, the numbers shown are not consistent The attached figures show the length LN is actually incorrect for the angle and side specified for triangle ACP, or the angles are incorrect for the side lengths specified. What this means is that the answers you get will depend on how you work the problem. Above, we have taken the given numbers and relationships at face value, even though we know they are incorrect.
Based on the side-splitter theorem, which side length would complete the proportion? StartFraction J M Over M K = StartFraction L N Over question mark EndFraction JL KL NK NM
Answer:
The correct answer is third option N K

NK

If you are considering speed regardless of direction, the average speed is:
(24 + 16) / 2 = 40 / 2 = 20mph
Although if direction matters, then one number has to be negative since the directions are opposite:
(24 - 16) / 2 = 8 / 2 = 4mph (in the positive direction)
manoj buys a leather coat costing Rs.900 at Rs 990 after paying the vat . calculate the rate of VAT changed on the coat .
Step-by-step explanation:
Original cost = 900
Cost after VAT = 990
VAT amount = 990 - 900 = 90
Rate of VAT = 90/900×100 = 90/9 = 10%

on a sunny day a goal post casts a 75 feet shadow. a 6 1/2 feet tall ball player standing next to the goal post has a shadow 19 1/2 ft. long how tall is the goal post
Answer: 62 Ft
Step-by-step explanation:
The shadow adds 13ft
How we know- 19 1/2 - 6 1/2 = 13 ft
So we need to take away 13ft to find out the goal post actual height

Are the lines y = –x – 4 and 5x -5y = 20 perpendicular? Explain.
Answer:
yes
Step-by-step explanation:
If 2 lines are perpendicular then the product of their slopes = - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x - 4 ← is in slope- intercept form
with slope m = - 1
5x - 5y = 20 ( subtract 5x from both sides )
- 5y = - 5x + 20 ( divide all terms by - 5 )
y = x - 4 ← in slope- intercept form
with slope m = 1
Thus product of their slopes is - 1 × 1 = - 1
Therefore the lines are perpendicular
You are shopping for school supplies and want to decide where you should buy pencils from. SupplyCo sells a 10 pack of pencils for $0.95. SchoolShop sells a 10 pack of pencils for $1.45 but you have a $3.00 coupon. How many packs of pencils would you have to buy for the prices to be the same at each store?
Answer:
120 (60 from each store)
Step-by-step explanation:
Given that:
Price for 10 pack of pencils at SupplyCo = $0.95
Price for 10 pack of pencils at SchoolShop = $1.45
Discount coupon at SchoolShop = $3.00
Let the number of packs of pencils bought = [tex]2x[/tex] (in pack of 10)
Then [tex]x[/tex] will be the number of packs of 10 bought at each store.
Therefore, price at SupplyCo for [tex]x[/tex] packs (in pack of 10) = [tex]0.95x[/tex]
And price at SchoolShop for [tex]x[/tex] packs (in pack of 10) = [tex]1.45x-3.00[/tex] (because there is a coupon of $3.00)
As per question statement, price at both the stores is same:
[tex]0.95x=1.44x-3\\\Rightarrow 0.5x=3\\\Rightarrow x=6[/tex]
Therefore, number of packs bought = [tex]2x\times 10 = 2\times 6\times 10 =\bold{120}[/tex] (60 from each store)

Which statement is true about vertical angles. 1 point Vertical angles are congruent if two lines are parallel. If vertical angles are congruent, then two lines are parallel. Vertical angles are always congruent. Vertical angles are supplementary if two lines are parallel.
Answer:
Vertical angles are always congruent.
Step-by-step explanation:
Vertical angles are formed when two straight lines intersect each other, thereby forming two pairs of opposite angles, which are called vertical angles. Thus, a pair of these vertical angles formed are congruent to each other. So therefore, if two angles are said to be vertical angles, it follows that they are congruent to each other.
Using the diagram attached below, we can see two straight lines intersecting each other to form two pairs of vertical angles:
<a and <b,
<c and <d.
Thus, <a is congruent to <b, and <c is congruent to <d.
Therefore, the standby that is true about vertical angles is that:
Vertical angles are always congruent.
i need help asapppppp
Answer:
A
Step-by-step explanation:
Supplementary angles are angles that add up to 180 degrees. Essentially, you can make a straight line with them.
1 and 7 are supplementary
1 and 4 are verticle, so no.
2 and 6 are complementary, so no.
3 and 6 are complementary, so no.

The required solution would be (1+7v)(3u+8b) of the given expression.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
We have been given the expression as:
⇒ 21uv + 8b + 3u + 56bv
There is v common in 21uv and 56bv
There is b common in 8b and 56bv
There is u common in 21u and 3u
We have to Add and subtract the second term to the expression and factor by grouping, we get
⇒ (1+7v)(3u+8b)
Therefore, the required solution would be (1+7v)(3u+8b) of the given expression.
