Answer:
L (4,-5)
Step-by-step explanation:
The transformation rule is (x,y) → (-y,-x) . This means that you are going to exchange your x and y and switch their signs.
1. Exchange - First you switch your points. (5,-4) → (-4,5)
2. Switch signs- -4 converts to 4 and 5 converts to -5
So your answer is L' (4,-5)

170 mm
83 mm
110 mm
Answer:
Perimeter of triangle PQR = 181.5 mm
Step-by-step explanation:
Midsegment theorem states that,
"Midsegment connecting the midpoints of the two sides of a triangle is parallel and half of the length of the third side"
From the figure attached,
PQ = [tex]\frac{1}{2}(EF)[/tex]
= [tex]\frac{83}{2}[/tex]
= 41.5 mm
PR = [tex]\frac{1}{2}(GF)[/tex]
= [tex]\frac{110}{2}[/tex]
= 55 mm
QR = [tex]\frac{1}{2}(GE)[/tex]
= [tex]\frac{170}{2}[/tex]
= 85 mm
Perimeter of triangle PQR = PQ + QR + PR
= 41.5 + 55 + 85
= 181.5 mm

Ayana and Victor have summer jobs selling newspaper subscriptions door-to-door, but their compensation plans are different. Ayana earns a base wage of $12 per hour, as well as $1 for every subscription that she sells. Victor gets $4 per subscription sold, in addition to a base wage of $6 per hour. If they each sell a certain number of subscriptions in an hour, they will end up earning the same amount. How many subscriptions would that be? How much would each one earn?
Answer:
2
$14
Step-by-step explanation:
Let x = number of subscriptions sold
Total income of Ayana per hour = $12 + $1x
Total income of Victor per hour = $6 + $4x
To find the number of subscriptions that would equate their incomes :
$12 + $1x = $6 + $4x
Collect like terms
$12 - $6 = $4x - $1x
$6 = $3x
Solve for x
x = $2
The subscription that would equate their income would be $2.
The income each would earn = $12 + $1(2) = $14
The value of x in the equation 161 - 6 - 26 is
Answer:
129
161-6=155-26=129 so x is 129
Answer:
x= 129
Step-by-step explanation:
161-6-26=x
161-6= 155
155-26= 129
x=129

Answer:
x=-8
Step-by-step explanation:
1) remove the constant(number without variable) to do this, we must use the opposite operation(in our case, subtraction)
so
4x+1=-31
a) 4x+1-1=-31-1
4x=-32
b) remove the coefficient by doing the opposite operation(division in our case)
x=-8

En un día de febrero, una ciudad de Estados Unidos registró una temperatura mínima de 9° bajo cero y una temperatura máxima de 13°C. ¿De cuántos grados fue el intervalo de temperaturas registradas?
Answer:
La cantidad de grados del intervalo de temperaturas registradas en el día de febrero mencionado es de:
5Step-by-step explanation:
En estadística, cuando se utilizan intervalos como valores para identificar datos cuantitativos, como en este caso temperaturas registradas, deben tomarse todos los valores, en este caso enteros, desde el límite inferior (temperatura mínima) hasta el límite superior (temperatura máxima), por lo cual no se puede restar el valor máximo al valor mínimo, sino que debes identificar todos los valores y después contarlos. En el caso del ejercicio dado, los grados en el intervalo mencionado son:
9°C10°C11°C12°C13°CComo puedes ver, los grados en el intervalo de temperaturas registradas serían 5.
Each figure is composed of large squares and small squares. The side length of the
large square is x. Write an expression for the area of the shaded part of each figure.
Figure A
Figure B
** Please help!!
Hey, did you get the expressions for both figure A and B? If so could you pls write them down below.
9514 1404 393
Answer:
A. x² -4
B. 2x² +8
Step-by-step explanation:
The area of the larger square is the square of its side length, so is x².
A. The area of each of the smaller squares is 1² = 1. There are 4 of them, so their total area is 4×1 = 4. The shaded area is that much less than the area of the larger square, so is ...
x² - 4
__
B. The smaller squares have side length 2, so their area is 2² = 4. There are two of them, so the total area of the smaller squares is 2×4 = 8.
The two large squares have a total area of ...
2 · x² = 2x²
So, the total shaded area is ...
2x² + 8

What is the value of y?
72°
A. 1080
B. 540
C. 36°
D. 720
Answer:
B. 54
Explanation:
Take 72 from 180.
180 - 72 = 108.
Since there are two y's AND they're congruent, divide 108 by two and get 54.
Tanya wants to sew her own jean jacket. She found a sewing pattern for her size and realized she
needs 4 yards of fabric. She goes to the store and finds the denim fabric she likes, which is priced
at $7.50 per yard. She also needs to buy buttons to put on the jean jacket. She finds a pack of
buttons priced at $6.99. How much will Tanya spend at the store on her fabric and buttons?
Answer:
$36.99
Step-by-step explanation:
Fabrics per yard = $7.50
Pack of buttons = $6.99
Fabrics needed = 4 yards
How much will Tanya spend at the store on her fabric and buttons?
Total cost of fabric and button = cost of 4 yards of fabric + pack of buttons
= 4(7.50) + 6.99
= 30 + 6.99
= 36.99
Total cost of fabric and button = $36.99
what is 2(3x-5) + 3(2x+3)
Answer:
12x - 1
Step-by-step explanation:
Distribute the 2 and 3:
2(3x - 5) + 3(2x + 3)
(6x - 10) + (6x + 9)
Add like terms:
12x - 1
So, the answer is 12x - 1

Enter the ordered pair for the vertices for 180°,0)(QRST).
Q
o
S
IR
O Q' = (-1,-3) R' = (-3,3 ) S'= (0,2)T' =(2, -1)
OQ' = (-1,3) R' = (-3,-3) S'=(0, -2)T' =(2, 1)
Q' = (1, -3) R' =(3,3) S' = (0,2)T' = (-2,-1)
Answer:
The ordered pair for the vertices for r₍₁₈₀ ₀₎(QRST), is given as follows;
Q' = (-1, -3) R' = (-3, 3) S' = (0, 2) T' = (2, -1)
Step-by-step explanation:
The coordinates of he vertices of the triangle QRST are;
Q(1, 3), R(3, -3), S(0, -2), T(-2, 1)
A rotation of a point with coordinates (x, y) 180° about the origin gives;
The coordinate of the point of the preimage before the rotation = (x, y)
The coordinate of the point of the image after the rotation = (-x, -y)
Therefore we have;
The image of point Q(1, 3) after 180° rotation = Q'(-1, -3)
The image of point R(3, -3) after 180° rotation = R'(-3, 3)
The image of point S(0, -2) after 180° rotation = S'(0, 2)
The image of point T(-2, 1) after 180° rotation = T'(2, -1)
The ordered pair for the vertices for r₍₁₈₀ ₀₎(QRST), is therefore, Q'(-1, -3), R'(-3, 3), S'(0, 2), and T'(2, -1);
Q' = (-1, -3) R' = (-3, 3) S' = (0, 2) T' = (2, -1).
