Answer:
The answer to your question is letter C
Step-by-step explanation:
(x² - 5x) + (2x² + 2x - 5)
Process
1.- Remove parenthesis without changing the sign of the terms
x² - 5x + 2x² + 2x - 5
2.- Simplify like terms
(x² + 2x²) + (-5x + 2x) - 5
3.- Result
3x² - 3x - 5
Answer:
x = 6
Step-by-step explanation:
Using the rules of logarithms
• log x - log y ⇔ log ( )
• x = n ⇔ x =
Given
log(5x) - log(x - 3) = 1
log ( ) = 1, then
= = 10 ( cross- multiply )
10(x - 3) = 5x
10x - 30 = 5x ( subtract 5x from both sides )
5x - 30 = 0 ( add 30 to both sides )
5x = 30 ( divide both sides by 5 )
x = 6
Using exponential function concepts, it is found that the correct option is:
domain: {x | x is a real number}; range: {y | y > –9}; asymptote: y = –9
<h3>What is an exponential function?</h3>
An exponential function is modeled by:
As for the characteristics of the function, we have that:
- The domain is of all real numbers.
- The range is the values of y greater than c, that is, {y| y > c}.
In this problem, the function is:
Hence c = -9, and the correct option is:
domain: {x | x is a real number}; range: {y | y > –9}; asymptote: y = –9

Answer:x = 60
Step-by-step explanation:
The given triangle is an equilateral triangle. This is so because all the angles are equal. This also means that all the sides are equal.
The sum of the angles on a straight line is 180 degrees. Assuming each angle of the equilateral triangle is y degrees, it means that
y + 2x = 180
y = 180 - 2x
The sum of the angles in a triangle is 180 degrees. It means that
y + y + y = 3y = 180
This means that
3(180 - 2x) = 180
540 - 6x = 180
6x = 540 - 180 = 360
x = 360/60 = 60
