Answer:
The coordinates of the reflected triangle are [tex]X'(x,y) = (-3,-2)[/tex], [tex]Y' (x,y) = (-5,1)[/tex] and [tex]Z'(x,y) = (2,-3)[/tex].
Step-by-step explanation:
Let be a point [tex](a,b)\in\mathbb{R}^{2}[/tex], reflections across x- and y-axes are represented by the following operations:
x-Axis reflection:
[tex]d = d'[/tex]
[tex]b - 0 = 0 - b'[/tex]
[tex]b' = -b[/tex]
y-Axis reflection:
[tex]d = d'[/tex]
[tex]a - 0 = 0 - a'[/tex]
[tex]a' = -a[/tex]
If we know that [tex]X (x,y) = (3,2)[/tex], [tex]Y(x,y) = (5,-1)[/tex] and [tex]Z (x,y) = (-2, 3)[/tex], the coordinates after both reflections are, respectively:
[tex]X'(x,y) = (-3,-2)[/tex]
[tex]Y' (x,y) = (-5,1)[/tex]
[tex]Z'(x,y) = (2,-3)[/tex]
The coordinates of the reflected triangle are [tex]X'(x,y) = (-3,-2)[/tex], [tex]Y' (x,y) = (-5,1)[/tex] and [tex]Z'(x,y) = (2,-3)[/tex].

Expand 3p(p+5)
Answer:
3p² + 15p
Step-by-step explanation:
We use distributive property to distribute 3p to each of the terms:
3p · p = 3p²
3p · 5 = 15p
3p² + 15p
Hey there!☺
[tex]Answer:\boxed{3p^2+15p}[/tex]
[tex]Explanation:[/tex]
[tex]3p(p+5)[/tex]
Let's expand.

Brick 38 g/20 cm
Oak wood: 56 g/80 cm
Wheat 24 g/30 cm
Butter: 8.7 g/10 cm
Answer:
Float in Water:
Wheat
Butter
Oak wood
Sink in Water:
Brick

Determine the solutions of the equation |x – 3| = 11. 1. Rewrite for two solutions: (x – 3) = 11, –(x – 3) = 11 Solve for x in each equation. What are the solutions to the equation? x = –14, –8 x = –14, 8 x = –8, 14 x = 8, 14
Answer: C. x=-8,14
Step-by-step explanation:
C
Answer:
x = 14, –8Step-by-step explanation:
|x – 3| = 11
(x - 3) = 11 - (x - 3) = 11
x - 3 = 11 - x + 3 = 11
x = 11 + 3 -x = 11 - 3
x = 14 -x = 8
x = -8

How many solutions does the following equation have?
3z + 9 + 142 = 4z + 5
Choose 1 answer:
A.No solutions
B.Exactly one solution
C.Infinitely many solutions
Answer:
Step-by-step explanation:
3z + 9 + 142 = 4z + 5
3z + 151 = 4z + 5
-z + 151 = 5
-z = -146
z = 146
answer is B
exactly one solution

If DE bisects <ABC.find the value of x if m<ABC=7x+29 and m<DBC=99°
Answer:
19
Step-by-step explanation:
If DE bisects <ABC, this means that <ABE = <EBC
Also <DBC+<EBC = 180
99+<EBC = 180
<EBC = 180-99
<EBC = 81
Also <ABC =<ABE+<EBC
<ABC =<EBC+<EBC
7x+29 = 81+81
7x = 162-29
7x = 133
x = 133/7
x = 19°
Hence the value of x is 19°

15. PART A: Write an algebraic expression for each verbal expression "the product of 9 and t squared, increased by the sum of the square of t and 2" *
Answer:
9t²+(t²+2)
Step-by-step explanation:
The product of 9 and t squared is expressed as 9×t² (product means multiplication)
9×t² = 9t²
Also, sum of the square of t and 2" is expressed as t² + 2 (sum means addition)
Finally, if the product of 9 and t squared, increased by the sum of the square of t and 2", the final expression will be the sum of the two expressions gotten. {Increment also means addition} i.e 9t²+(t²+2)
The algebraic expression is 9t²+(t²+2)

If m∠PTQ = 3y –10 and m∠QTR = y, find the value of y so that ∠PTR is a right angle
Answer:
y = 25
Step-by-step explanation:
Given that,
m∠PTQ = 3y –10 and m∠QTR = y
We need to find the value of y so that ∠PTR is a right angle.
For a right angle, one of the angle is 90 degrees. The sum of the angle of a triangle is equal to 180 degrees. So,
3y –10 + y + 90 = 180
Taking like terms together
3y+y = 180 -90 +10
4y = 100
y = 25
So, the value of y is 25.

A hockey game had 2,058 fans Friday night. The baseball game has 1,300 fans that night. How many more fans were at the hockey game?
Subtract the number at the baseball game from the hockey game:
2058 - 1300 = 758
There was 758 more people at the hockey game.
Answer:
758 more fans were there
Step-by-step explanation:
Difference = Hockey fans - Baseball fans
= 2058 - 1300
= 758
Delilah and a group of friends had excellent service at a restaurant. They would like to give the server a 25 percent gratuity on their $140 bill. Use the diagram to identify the amount of the tip.
A 2-column table with 5 rows. Column 1 has entries 25 percent, 25 percent, 25 percent, 25 percent, Total 100 percent. Column 2 has entries blank, blank, blank, blank, Total 140 dollars.
Answer:
The tip is 35 dollars
Step-by-step explanation:
Divide 140 by 4 to get 25%
140/4 = 35
35+35+35+35 = 140
25% of 140 = 35
The tip is 35 dollars
