<h3>Answer: C) a 180 degree rotation about its center</h3>

Explanation:

Draw out a rectangle and make sure it's not a square. So you could have it be longer than it is tall. Imagine rotating that rectangle 180 degrees. The before and after (preimage and image) will be identical. The same applies if we slanted the sides of this rectangle. This shows that any parallelogram has rotational symmetry.

Side note: any rectangle is a parallelogram, but not the other way around.

Which equation represents the line that passes through points (1 -5) and (3 -17)

Fynjy0 [20]

Answer:

6x-11

Step-by-step explanation:

m=y2-y1

x2-x1

-17--5 = -12

3-1. -2

The two negatives cancel ❌

m=12

Divide by 2

m=6

y=mx+b

-5= 6 (1) + b

-5= 6 + b

Subtract (6) from both sides

b= -11

The equation for the line is 6x -11

What k-1/3=5/6 equal ?

JulijaS [17]

The value of "K"

$k -\frac{1}{3} = \frac{5}{6}$

MMC (3,6)
3,6 | 3
1,2 | 2
1,1 |__ 3*2 = 6

Solving:
$k -\frac{1}{3} = \frac{5}{6}$
$\frac{6k}{6} - \frac{2}{6} = \frac{5}{6}$
cancel denominators (6)
$6k - 2 = 5$
$6k = 5+2$
$6k = 7$
$\boxed{k = \frac{7}{6} }$

If 141 people attend a concert and tickets for adults cost $3.5 while tickets for children cost $2.5 and total receipts for the

Arturiano [62]

Answer: There are 69 adults and 72 children went to the concert.

Step-by-step explanation:

Let x be the number of adults, and y be the number of children.

x + y = 141

3.5x + 2.5y = 421.5

x + y =141

x = 141 - y

3.5(141 - y) + 2.5y = 421.5

493.5 - 3.5y + 2.5y = 421.5

493.5 - y = 421.5

-y = -72

y = 72

x + y = 141

x + 72 = 141

x = 69
