What is the value of x?
Marysya12 [62]
A triangle always adds up to 180 degrees:

Therefore, 48 + 6x + 9x-3 = 180

Solve for x:

180 - 45 = 15x
135 = 15x

x = 9 degrees

Convert 124/10 into a mixed number
serious [3.7K]
To do  this simply see how many times 10 can go into 124.

It can go in 12 times right?

12 is your whole number.

The four is still left and it is going to stay there.  So right now you have:
12 and 4/10

4/10 can be simplified by dividing it by 2.

This leaves you with 2/5

Your answer is 12 and 2/5

Identify the inverse of the following.
posledela

Answer:

f^{-1}(x)=\sqrt{\frac{1}{8}(-x+4)}

Step-by-step explanation:

Given function is,

f(x) = -8x² + 4

Step to find the inverse of the function,

Step 1

Write the function in the form of an equation,

y = -8x² + 4

Step 2

Interchange the variables 'x' and 'y',

x = -8y² + 4

Step 3

Solve the equation for y,

x = -8y² + 4

x - 4 = -8y²

-x + 4 = 8y²

y² = \frac{1}{8}(-x+4)

y=\sqrt{\frac{1}{8}(-x+4)}

Therefore, inverse of the function f(x) will be,

f^{-1}(x)=\sqrt{\frac{1}{8}(-x+4)}
