Answer:
A'(0, 0), B'(-6, -18), C'(0, -12)Step-by-step explanation:
Rotation 180° is the transformation ...
(x, y) ⇒ (-x, -y)
Dilation by a factor of 3 is the transformation ...
(x, y) ⇒ (3x, 3y)
The two transformations together can be described by ...
(x, y) ⇒ (-3x, -3y)
That is, the coordinates of A, B, C are each multiplied by -3. The image vertices are ...
A' = -3A = A'(0, 0) . . . . . . . . the center of rotation and dilation is invariant
B' = -3B = B'(-6, -18)
C' = -3C = C'(0, -12)
Any dilated figure will not be congruent to the original. The triangles are similar.

The base fare per ride on the MTA bus or subway is $2.75, but you get a 5% discount with a purchase. A weekly unlimited MetroCard costs $32.00. How many rides a week will make the weekly unlimited pass more cost-effective?
"13" or "more than 13" rides will make the weekly unlimited pass more cost effective. A further solution is provided below.
The given values are:
Base fare per ride = $2.75Discount = 5%Weekly unlimited Metro Card costs = $32The Fare after discount will be:
= [tex]2.75\times \frac{100-5}{100}[/tex]
= [tex]2.75\times \frac{95}{100}[/tex]

How many packages of light fixtures and how many packages of light bulbs did Mr. Santiago buy?
I WILL GIVE BRANLIEST PLEASE HELP AND RIGHT ANSWER
Answer:
3 and 4 packagesStep-by-step explanation:
We need to find the LCM of 12 and 9.
9 = 3*312 = 2*2*3Their LCM is:
LCM(12, 9) = 2*2*3*3 = 36Number of light fixtures and light bulbs is 36.
Number of packages will be:
36/12 = 3 and36/9 = 4 respectively.Step-by-step explanation:
First finding LCM of 9 and 12
9 = 3 × 3
12 = 2 × 2 × 3
LCM = 3 × 2 × 2 × 3
LCM = 36
Now,
No. of light fixtures = 36/12 = 3
No. of light bulb = 48/12 = 4

Which is better to buy? 3-yard roll of wrapping paper for $7.02. 8-foot roll of wrapping paper for $7.36
Answer:
3 yard roll of wrapping paper for $7.02 is better to buy.
Step-by-step explanation:
1 yard = 3 foot
3 yard = 9 foot
$7.02 / 9 foot = $0.78/foot
$7.36 / 8 foot = $0.92/foot
0.78 < 0.92
Therefore, 3 yard roll of wrapping paper for $7.02 is better to buy.

. Find the sum of the first 20 terms of the
arithmetic sequence 27, 22, 17, ....
Answer:
Step-by-step explanation:
a = 27
n = 20
d = -5
L20 = 27 + (n - 1)*d
L20 = 27 + (20-1)*_5
L20 = 27 + 19*-5
L20 = -68
Sum = (a + L)*n/2
Sum = (27 - 68)*20/2
Sum = -41 * 10
Sum = - 410

the length of an arc is 10cm find angle subtended by arc if the circumference of the circle of which the arc form part 60cm
9514 1404 393
Answer:
60° = π/3 radians
Step-by-step explanation:
The 10 cm length of the arc is 1/6 of the 60 cm length of the circumference of the circle. That means the angle measure of the arc is 1/6 of the total angle measure of a circle.
arc = 360°/6 = 60°
arc = (2π radians)/6 = π/3 radians
-3/4(8n+12)=3(n-3) show work pls
Answer: n = 0
Step-by-step explanation:
Given expression
(-3/4) (8n + 12) = 3 (n - 3)
Expand parentheses and apply the distributive property
-6n - 9 = 3n - 9
Add 9 on both sides
-6n - 9 + 9 = 3n - 9 + 9
-6n = 3n
Subtract 3n on both sides
-6n - 3n = 3n - 3n
-9n = 0
Divide -9 on both sides
-9n / -9 = 0 / -9
[tex]\boxed{n=0}[/tex]
Hope this helps!! :)
Please let me know if you have any questions
Answer:
0
Step-by-step explanation:

-6n-9=3n-9
-6n-3n-9=-9
-9n-9=-9

Answer:
30+(2x+7)+63=180(sum of angles of triangle )
30+2x+7+63=180
2x+100=180
2x=180-100
x=80/2
x=40
Answer:
[tex]\boxed {\boxed {\sf (2x+7)+30+63= 180}}[/tex]
[tex]\boxed {\boxed {\sf x=40}}[/tex]
Step-by-step explanation:
We are asked to write an equation to solve for x and use the equation to find x.
We know that the angles in a triangle must add to 180 degrees. Therefore, the sum of the three angles in this triangle: 30, 63, and (2x+7) must equal 180. We can set up an equation.
[tex](2x+7)+ 30 +63= 180[/tex]
Now we can use the equation to solve for x. First, we combine like terms on the left side of the equation. The 3 terms without variables or constants can be added.
[tex]2x+ (7+30+63)= 180[/tex]
[tex]2x+ (100)= 180[/tex]
We are solving for x, so we must isolate the variable. 100 is being added to 2x. The inverse operation of addition is subtraction. Subtract 100 from both sides of the equation.
[tex]2x+100-100= 180-100 \\2x=180 -100 \\2x=80[/tex]
x is being multiplied by 2. The inverse operation of multiplication is division. Divide both sides of the equation by 2.
[tex]\frac {2x}{2}= \frac{80}{2}[/tex]
[tex]x= \frac {80}{2} \ \\[/tex]
[tex]x=40[/tex]
The equation is (2x+7)+ 30+63= 180 and x is equal to 40.
