The answer is: -3y+9z
This is because you simply switch the sign for every number in the parentheses.
Hope this helps!
I think you forgot to attach the graph along with the question. I am answering the question based on my knowledge and research. "y = −2x − 1" is the one equation among the following choices given in the question that <span>represents the graph of the linear function. The correct option among all the options that are given in the question is option "B".</span>
Answer:
Step-by-step explanation:
<u>Biquadratic Equations</u>
Solve:
The biquadratic equations are equations of degree 4 without the terms of degree 1 and 3.
Solving such equations requires to express the equation as a second-degree equation with as the variable.
Rewriting the equation:
The quadratic equation can be factored as:
It leads to two equations:
The first equation has imaginary roots. Solving for x:
Where
The second equation has two real roots:
The roots are:
4/5 - 1/6
= 24/30 - 5/30
= 19/30
Answer:
The lines are parallel.
Step-by-step explanation:
Given the lines
Writing the equations in the slope-intercept form
where m is the slope and b is the y-intercept
Thus, the slope = m₁ = -2/3
also
Thus, the slope = m₂ = -2/3
- We know that parallel lines have equal slopes
As
m₁ = m₂
Thus, the lines are parallel.
