Answer:
A. 2x - 1
Step-by-step explanation:
We want the price of each notebook, so we will get this equation.
(4x^2 + 2x + 1) / (8x^3 - 1) [ The " / " sign means I wrote as a fraction. ]
After that, we will use this method to factor ( 8x^3 - 1 ).
a^3 - b^3 = ( a - b )( a^2 + ab + b^2 )
1 can be wrote as 1^3 as we still get the same answer.
8^3 - 1^3 = ( 2x - 1 )( 4x^2 + 2x + 1)
So, we will get this.
(4x^2 + 2x + 1) / ( 2x - 1 )( 4x^2 + 2x + 1)
Now, we can cross out the ( 4x^2 + 2x + 1 ).
We will be left with 1 / ( 2x - 1 ).
Flip it and we will get ( 2x - 1 )
And that is the answer.
I hope it helps.
Jade got a 90% on her math quiz. She had 36 questions correct. How many questions did Jade get wrong?
Answers
Answer:
4 questions
Step-by-step explanation:
90% is the same as multiplying a number by 0.9. Let's say the number of questions on the quiz is x. This means the amount she got right was 0.9x. We are given this is 36, so we can set them equal and simplify:
0.9x = 36
x = 40
She must have gotten 40 - 36, or 4 questions wrong.

HELP!! DONT STEAL MY POINTS OR ANSWER AND THEN DELETE IT!! Which is the orthocenter of a triangle with vertices (-2, 1), (3, 4), and (3, -4) ?
Answers
Answer:
(0, 1)
Step-by-step explanation:
The orthocenter is the point of intersection of the altitudes of the triangle. Each altitude is a line through a vertex and perpendicular to the opposite side.
In the attached, we labeled the points A, B, C in the order given. Side BC of the triangle is vertical, so the horizontal line through A will have equation ...
y = 1
The line AC can be seen on the graph to have slope -1, so the altitude through point B will have slope 1. Its equation will be ...
y = x+1
Then the point of intersection will be where ...
y = y
1 = x+1
0 = x
That is, the orthocenter is the point (x, y) = (0, 1).

Move all the variables to the left, using the opposite operation:

9n-5n=72
4n=72
Divide both sides by 4 to isolate n:
n=18

B. y= -2x+3
Step-by-step explanation:
1) the slope-interception form is: y=s*x+i, where s - slope, i - interception are unknown numbers;
2) if y(0)=3, then i=3, it means the equation is y=s*x+3;
3) if to substitute x=1; y=1 into the equation y=s*x+3, then s= -2. It means, the initial equation is y= -2x+3.
4) finally, the correct answer is B.

Heather ran a race at a constant rate. The table shows the time she reached each mile marker.
Let X represent the mile marker reached and let y represent the overall time passed.
Mile Marker: 0 | 1 | 2 | 3
Time (min): 0 | 8 | 16 | 24
(a) Write the equation in point-slope form to represent the mile reached over time
(b) Find the total time it will take Heather to run a 9-mile race if she maintains the same rate. Explain your reasoning.

Answer:
y − 8 = m(x − 1)
72 minutes
Step-by-step explanation:
Point slope form is: y − y1 = m(x − x1)
Pick any two points. I'll pick (1,8) and (2,16). I will make the first point the (x1,y1) we need for the point slope equation:
y − y1 = m(x − x1)
y − 8 = m(x − 1)
We can calculate the slope, m, by determining the Rise/Run of the line. The Rise is the change in y for the Run, the change in x.
Change in Run (x) = (2-1) = 1
Change in Rise (y) = (16-8) = 8
Slope (Rise/Run) = 8
m is 8
y − 8 = m(x − 1)
y − 8 = 8(x − 1)
or
y = 8x
We can now predict Heather's time to complete the 9 miles:
y = 8x
y = 8*(9)
y = 72 minutes
