Answer:
A)
B)
Step-by-step explanation:
On the left, we have five (positive) Xs and one -1. So, we can represent the left with the expression .
On the right, we have six -1s. So, we can represent the right with the expression .
A)
Since the balance is balanced, we know that the two expressions are equal to each other. So, we can write the equation:
B)
Now, we can solve the equation for x. Add 1 to both sides:
The left will cancel. Add on the right:
Finally, divide both sides by 5:
The left side will cancel. So, the value of x is:
Answer:
y = 4x^5 - 12x^4 + 6x and
y = 5x^3 - 2x
Step-by-step explanation:
The system of equations that can be used to find the roots of the equation 4x^5-12x^4+6x=5x^3-2x are;
y = 4x^5 - 12x^4 + 6x and
y = 5x^3 - 2x
We simply formulate two equations by splitting the left and the right hand sides of the given equation.
The next step is to graph these two system of equations on the same graph in order to determine the solution(s) to the given original equation.
The roots of the given equation will be given by the points where these two equations will intersect.
The graph of these two equations is as shown in the attachment below;
The roots are thus;
x = 0 and x = 0.813

Answer:
Choice C
Step-by-step explanation:
First when we are looking for a system of equations that has no solution we are looking for two lines that won't intersect and the only lines that would never intersect are parallel lines.
Ok so what we are looking for is an equation with the same slope but different y-intercept. A parallel line should go at the same rate like the other line but shouldn't start at the same point.
<em><u>Analysing Choice A:</u></em>
We just said that the slope has to be the same so this one can't be it.
<em><u>Analysing Choice B:</u></em>
For this one we have to put it in slope-intercept-form.
So we see that the slope is the same for this one and and the y-intercept is also the same which is NOT what we need so on tho the next one.
<em><u>Analysing Choice C:</u></em>
For this one we also have to put it in slope-intercept-form.
We see that the slope are the same and the y-intercept are different so this is the one we are looking for.
Sorry but for the sake of time I won't analyze choice D.
