Answer:

see explanation

Step-by-step explanation:

To obtain a solution for cos^{-1} (x) , then

- 1 ≤ x ≤ 1

That is the value of x cannot be greater than 1 or less than - 1

here x = \frac{5}{4} = 1.25 which is greater than 1 , thus calculator will return ' error'

42-x=58

or, -x=58-42

with change in side sign also chamges we change sides to make like terms in one side and unlike in amother side.

or, -x= 16

or,x=-16.

therefore x=-16...

What is the slope of the equation y – 3 = –4(x – 5)?
Gemiola [76]
Find the x and y intercepts or any other 2 points. (I advise you finding the y intercept though.)

then calculate for slope using:
y(2) - y(1)
________
x(2) - x(1)

The (2) and (1) are not exponents they are small numbers at the bottom of the numbers.

The slope is: 4
