Pavlova-9 [17]

Answer:

40

Step-by-step explanation:

Ok, so basically let's start with a proportion.

x/32 = 11.25/9

Cross multiply:

x * 9 = 32 * 11.25

9x = 32 * 11.25

9x = 360

Solving for variable 'x'.

Divide each side by '9'.

x = 40

I don't know if this is the correct answer, but it was based on my math. I hope this helps!

Use complete sentences to describe why it is valid to say that both a function and its inverse describe the same relationship.
Serhud [2]

Answer:

Step-by-step explanation:

A comparison between a function and its inverse would show that the domain and range of the original function swap. The domain of the function becomes the range of the inverse, the range of the function becomes the domain of its inverse. 

Looking at ordered pairs of the function and its inverse would look like this:

(2,4) on the original function becomes (4,2) on the inverse. 

While the graph of a function and its inverse are noticeably different an important thing to note is that it is merely a reflection across the line y=x. 

So even though they appear different you are looking at the same relationship just as y vs. x instead of x vs. y

I hope this helped you because i barley understood this myself.

Jake is choosing between 2 cell phone plans. Plan A costs $15 per month plus $0.08 per minute. Plan B costs $35 per month for un
Alex73 [517]

Answer:

The system of equations is

y=0.08x+16

y=35

Step-by-step explanation:

Let

x ----> the number of minutes of calling time

y ----> the monthly cost of the calling plan

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

In this problem

Plan A

m=0.08\\b=16

substitute

y=0.08x+16 ----> equation A

Plan B

m=0\\b=35

substitute

y=35 ----> equation B

therefore

The system of equations is

y=0.08x+16

y=35

The area of a trapezium is 35cm2.find its altitude if the bases is 6cm and 8cm​
r-ruslan [8.4K]

Answer: altitude: 5 cm

Explanation:

\sf \dfrac{1}{2}  ( a + b) h = Area \ of \ trapezium

[ <u>a and b are bases, h is the altitude</u> ]

Here given:

  • Area = 35
  • a = 6
  • b = 8
  • h = ?

Solve for altitude:

\sf \rightarrow \sf \dfrac{1}{2}  ( 6 + 8) h = 35  \ \  \  \Rightarrow  \ \ \ \dfrac{1}{2}  ( 14) h = 35 \ \ \ \ \Rightarrow   \ \ \  \ 7 h = 35 \ \ \ \  \Rightarrow \ \   h = \dfrac{35}{7} \   =  \  5
