Answer:

Heya mate here's the answer

let the 4th angle be x

so 75°+ 75°+75° +x= 360°

=> x= 360 - 225

=> x = 135°  

therefore the 4th angle= 135°

hope this helps

Feliz [49]

Alang must visit 8 times to the theatre to earn a free movie ticket.

<h3>What is an expression?</h3>

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Given that Alang has a points card for a movie theatre. He receives 55 reward points just for signing up. He earns 3.5 points for each visit to the movie theatre. He needs 83 points for a free movie ticket.

Form an equation and calculate the number of tickets:-

55 + 3.5N = 83

3.5 N = 83 - 55

3.5N = 28

N = 28 / 3.5

N = 8

Therefore, Alang must visit 8 times to the theatre to earn a free movie ticket.

Which function is the inverse of f(x) = –5x – 4?
Finger [1]

Answer:

f^(-1)(x) = \frac{-1}{5} (x+4)

Step-by-step explanation:

Given is a function

f(x) = -5x-4\\

To find its inverse.

We must check whether f is one to one or onto first

If -5x1-4 = -5x2-4 we get x1=x2

Hence f is one to one

Also for every f(x) we can find a x so f is onto.

So inverse exists

Let

y=-5x-4\\-5x=y+4\\x=\frac{-1}{5} (y+4)

Replace x by f inverse and y by x

f^(-1)(x) = \frac{-1}{5} (x+4)
