Answer:

Step-by-step explanation:

C and D are both wrong for the same reason. The denominator should be (x +1)*5 which means that either A or B is correct.

C and D have an error seldom seen on Brainly. It means that the denominator has been added rather than multiplied but even the addition is a little strange. Frankly, I don't know what has to be done to get either of them.

So the answer is

numerator: 5*(x + 9) + (x + 1)(x - 2)

denominator: 5*(x + 1)

Simplify the numerator. Remove the brackets.

numerator: 5x + 45 + x^2 - 2x + x - 2 Gather like terms

numerator: x^2 + 5x - 2x + x + 43 Simplify

numerator: x^2 + 4x + 43

Answer

x^2 + 4x + 43

==========

5(x + 1)

How would I find the domain and range of this graph?

matrenka [14]

Answer:

Domain: [-3, 5]

Range: [-5, 4]

Step-by-step explanation:

The first thing is to define what is the domain and the range. The domain of a function f (x) is the set of all the values for which the function is defined, and the range of the function is the set of all the values that f takes.

In other words, the domain is the value on the "x" axis and the range is the value on the "y" axis.

In this case, both are an interval, the domain would be from -3 to 5 and in the case of the range it would be from -5 to 4.

Domain: [-3, 5]

Range: [-5, 4]

Answer:

$x\approx7.8$

Step-by-step explanation:

In relation to the given angle, we are given the triangle's opposite side and hypotenuse. Therefore, we use the sine function to set up a proportion and solve for the opposite side:

$sin(\theta)=\frac{opposite}{hypotenuse}$
