Find the sides, and the value of x and y.
Gelneren [198K]

Answer:

\huge\boxed{x=15;\ y=4}

Step-by-step explanation:

Proportion:

\dfrac{x}{18}=\dfrac{5}{6}\qquad|\text{cross multiply}\\\\(x)(6)=(18)(5)\\\\6x=90\qquad|\text{divide both sides by 6}\\\\\huge\boxed{x=15}

\dfrac{y}{5}=\dfrac{12}{x}

substitute x = 15:

\dfrac{y}{5}=\dfrac{12:3}{15:3}\\\\\dfrac{y}{5}=\dfrac{4}{5}\qquad|\text{cross multiply}\\\\(y)(5)=(5)(4)\\\\5y=20\qquad|\text{divide both sides by 5}\\\\\huge\boxed{y=4}

Graph  image 1  for  translation. one unit to the right
rodikova [14]
We use the following reflection rule:
 (x, y) = (x + 1, y)
 We have then:
 M (-3, 1) ---> M '(- 2, 1)
 O (1, 4) ---> O '(2, 4)
 P (3, -1) ----> P '(4, -1)
 Answer:
 The new vertices are
 M '(- 2, 1)
 O '(2, 4)
 P '(4, -1)
 Graph five (last from left to right) is the correct one.

Mice21 [21]

Answer:

The number of people that attended the performance = 2,254

Amount collected at box office = $45,080

Step-by-step explanation:

For the theater to sell out a performance, it means it was filled to the brim( completely filled)

We have 7 sections, with 23 rows each

The total number of rows will be 23 * 7 = 161 rows

Since each row has 14 seats, the total number of seats will be 161 * 14 = 2,254 seats

Secondly we want to know how much was collected at the box office given the average ticket price

The amount collected at the box office = Number of seats * average ticket price = 2,254 * 20 = $45,080
