Answer: About -5 new production per year.

Step-by-step explanation:

Given : In 1980, there were 67 new productions on Broadway.

In 1987, there were 31 new productions on Broadway.

Now, the average rate of change in the number of new productions is given by :-

\text{Average rate of change}=\dfrac{\text{Production in 1987-Production in 1980}}{1978-1980}

i.e.

\text{Average rate of change}=\dfrac{31-67}{7}\\\\=\dfrac{-36}{7}=-5.142857142\approx-5

Hence, the average rate of change in the number of new productions is about -5 new production per year.

Domain of the function f(x)=3x/4x^2-4
yaroslaw [1]

Answer:

the complete question in the attached figure


we have that

f(x)=3x/(4x²-4)


we know that

the denominator can not be zero

so

(4x²-4)=0

4x²=4

x²=1----> x=(+/-)√1

x1=1

x2=-1

the values ​​of x=1 and x= -1 make the denominator zero, therefore they do not belong to the domain of the function


the answer is

the domain of the function is all real numbers except 1 and -1

Find the value of X.
Oksanka [162]

Answer:

x =25

Step-by-step explanation:

This is an isosceles triangle because RS = ST

that means <r = <STR

4x-70 = STR

<STR + <STU = 180   straight line

subtract < STU from each side

<STR = 180 -<STU

we know angle stu = 6x

<STR = 180 -6x

we can substitute this into 4x-70 = STR

4x-70 = 180 -6x

add 6x to each side

4x+6x -70 = 180 -6x+6x

10x -70 = 180

add 70 to each side

10x-70+70 = 180+70

10x=250

divide by 10

10x/10 = 250/10

x =25

help with this please
Ierofanga [76]

Answer:

see explanation

Step-by-step explanation:

Under a translation < 5, - 9 >

5 is added to the original x- coordinate and 9 is subtracted from the original y- coordinate, that is

A(1, 4 ) → A'(1 + 5, 4 - 9 ) → A'(6, - 5 )

B(2, - 2 ) → B'(2 + 5, - 2 - 9 ) → B'(7, - 11 )

C(- 3, 2 ) → C'(- 3 + 5, 2 - 9 ) → C'(2, - 7 )
