Answer:
17x-12
Step-by-step explanation:
combine like terms. 12x and 5x go together to make 17x. 4 and -16 go together to make -12
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
y=x^2-x+1
We want to solve for x.
I'm going to use completing the square.
Subtract 1 on both sides:
y-1=x^2-x
Add (-1/2)^2 on both sides:
y-1+(-1/2)^2=x^2-x+(-1/2)^2
This allows me to write the right hand side as a square.
y-1+1/4=(x-1/2)^2
y-3/4=(x-1/2)^2
Now remember we are solving for x so now we square root both sides:

The problem said the domain was 1/2 to infinity and the range was 3/4 to infinity.
This is only the right side of the parabola because of the domain restriction. We want x-1/2 to be positive.
That is we want:

Add 1/2 on both sides:

The last step is to switch x and y:



 
        
             
        
        
        
Well, "minus 6 x cubed minus y squared minus 3 x y" translates to:

Then, if we insert the values for x and y, we get:

When we distribute and multiply:

And once we combine like terms:

4(x + 3) = 6 - x
First, expand to remove parentheses.
 Second,
Second, subtract '6' from both sides.
 Third,
Third, subtract '12 - 6' to get 6.
 Fourth,
Fourth, subtract '4x' from both sides.
 Fifth,
Fifth, since 'x' can be referred to as '1', add it to '4x' to get '-5x'.
 Sixth,
Sixth, divide both sides by '-5'.
 Seventh,
Seventh, change the whole fraction into a negative.
 Eighth,
Eighth, switch your sides.

The phrase best describes the range of the function h(x) is option A: all real numbers.
<h3>What is a range of a function?</h3>
The range is the set of all values which the given function can output.
A step function h(x) is represented by y = -2|x|.
The mode of x gives the real number every time by putting the values.
