Solve for x. 3/x-1 - 1/x^-1=5/x-1
Please show all work
3/(x-1) - 1/(x^2-1) = 5/(x-1)
Subtract 3/(x-1) from both sides
-1/(x^2-1) = 2/(x-1)
Factor x^2 - 1
-1/[(x-1)(x+1] = 2/(x-1)
Multiply by (x-1)(x+1) on both sides
-1 = 2 (x+1)
-1 = 2x + 2
Subtract 2 from both sides
-3 = 2x
Divide by 2 on both sides
-3/2 = x
Answer:
x = -3/2

Find measure of arc CE
A. 40°
B.50°
C.75°
D.80°
Answer:
Option B is the right choice.
Step-by-step explanation:
Given:
An are CE and an inscribed angle CBE.
Measure of inscribed angle CBE = 25 °
We have to find the measure of the arc CE.
Concept:
An inscribed angle is an angle with its vertex on the circle.The measure of an inscribed angle is half the measure the intercepted arc. Measure of inscribed angle = 1/2 × measure of intercepted arc .To find the measure of arc CE.
⇒ [tex]\angle CBE = \frac{1}{2} \times m\ (arc\ CE)[/tex]
⇒ [tex]2\times \angle CBE = m\ (arc\ CE)[/tex]
⇒ [tex]2\times 25 = m\ (arc\ CE)[/tex]
⇒ [tex]50 = m\ (arc\ CE)[/tex]
Measure of intercepted arc CE = 50 degrees.
The measure of arc CE = 50° so, option B is the right choice.

The nth term of a sequence is 8 - n. a)work out the first three terms of the sequence b) work out the value of the first negative term of the sequence
Answer:
see explanation
Step-by-step explanation:
To calculate the first 3 terms substitute n = 1, 2, 3 into the n th term formula
(a)
8 - 1 = 7
8 - 2 = 6
8 - 3 = 5
The first 3 terms are 7, 6, 5
(b)
The first negative term wii occur when n > 8, that is n = 9, thus
8 - 9 = - 1 ← first negative term
The first three terms of the sequence defined by 8 - n are 7, 6, and 5. The first negative term is when n equals 9.
Explanation:The nth term of a sequence is defined by 8 - n. This means that you subtract the term number (n) from 8 to get the value of the term.
To work out the first three terms of the sequence, substitute n = 1, 2, and 3 into the nth term. So, the first term is 8 - 1 = 7, the second term is 8 - 2 = 6, and the third term is 8 - 3 = 5.To find the first negative term of the sequence, you need to determine the value of n when 8 - n becomes less than 0. If you set 8 - n to be less than 0 and solve for n, you will find that n > 8. Therefore, the first negative term occurs when n = 9 (since n must be an integer, the number immediately greater than 8 is 9).Learn more about Sequence Terms here:https://brainly.com/question/35448108

When does the graph of a quadratic function open up?open down?
The graph of a quadratic function opens up when a (<,>,=) 0 and opens down when a (<,>,=) 0
Answer:
1. >
2. <
Step-by-step explanation:
When a > 0, the graph opens upwards, or positively, because the way the line curves is determined by a.
When a < 0, the graph opens downwards, or negatively, for the same reason.
Final answer:
The graph of a quadratic function opens upwards when the coefficient of the squared term is positive (a > 0), and opens downwards when this coefficient is negative (a < 0).
Explanation:
The graph of a quadratic function opens up or down based on the sign of the coefficient of the squared term (usually represented as 'a' in the quadratic equation ax2 + bx + c). When this coefficient a is positive (a > 0), the parabola opens upwards. Conversely, if the coefficient a is negative (a < 0), the parabola opens downwards. The orientation of the parabola reflects whether the quadratic function has a minimum value (opening upwards) or a maximum value (opening downwards).

Absolute 10.7 of percent 11
Answer: = 11.88
This is a 3 step / 4 show workings.
10.7 + Percentage increase = 11%
10.7 + (11% × 10.7) = 10.7 + 11% × 10.7
(1 + 11%) × 10.7 = (100% + 11%) × 10.7
111% × 10.7 = 111 ÷ 100 × 10.7

1. What is the probability of rolling a number less
than 3 or a six on a standard 6-sided die?
a. 1/6
b. 1/3
c. 1/2
d. 1
e. 3
I'm giving 20 points if you answer correctly
Answer:
1/2
Step-by-step explanation:
There are 2 numbers less than 3. (1 and 2) and one 6 on a dice. Therefore there is a 3 out of 6 chance of rolling one of these 3 numbers (1, 2, and 6). This can be represented as 3/6 which would simplify to 1/2 or 50%.
It can also be found this way...
Probability = Number of desired outcomes ÷ number of possible outcomes. Therefore 3 ÷ 6 = 0.5 which is equal to 50% or 1/2.

Thus the triangle with legs 12 and 2 × 8 = 16 is right
Using Pythagoras' identity.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
?² = 12² + 16² = 144 + 256 = 400 ( take the square root of both sides )
? = [tex]\sqrt{400}[/tex] = 20
Final answer:
The question deals with mathematics, specifically the slope of tangent lines, use of the Pythagorean theorem, and solving scale ratios and proportions. Students need to find specific lengths using provided endpoints, hypotenuse calculations, and scale conversions.
Explanation:
The student appears to be asking about finding the length of a line segment in a geometric context, possibly related to tangents to curves and the Pythagorean theorem. The student is likely working with a diagram or curve not provided here, so it is important to make use of available data points or diagrams in the course material. Furthermore, when working with scales and ratios for determining lengths, the process involves setting up a proportion, solving for the unknown value by cross-multiplying and dividing.
For the slope of the tangent line to a curve:
Identify the endpoints of the tangent line that corresponds to given positions and times.
Find the slope of the tangent line, denoted as 'v', by using the change in position over the change in time.
For the Pythagorean theorem:
Calculate the length of the hypotenuse as the square root of the sum of the squares of the other two sides.
Use significant figures appropriately to represent the precision of your result.

Which triangle defined by the given points on the coordinate plane is similar to the triangle illustrated?
Answer:
The correct option in the attached image is:
D. (-1, 1), (-1, 5), (-7, 1)
Step-by-step explanation:
Please refer to the attached image.
The length of the horizontal segment of the graphed triangle is 3. The length of the vertical segment of the triangle graphed is 2. We will use the Pythagorean theorem to find the length of the missing side thus:
x² = 2²+3²
x² = 4+9
x² = 13
x = √13 or 3.6
This makes our side lengths 2, 3, and 3.6
For option A, our vertices are (-1, 1), (-1, 4), (-6, 1). This means the length of the horizontal segment 5 and the length of the vertical segment 3. This missing side length is calculated thus:
x² = 5²+3²
x² = 25+9
x² = 34
x = √34 or 5.83
This is not proportional to the triangle drawn, so it is not similar.
For option B, our vertices are (-1, 1), (-1, 5), and (-6, 1). This makes the horizontal segment 5 units long and the vertical segment 4 units long. This makes the missing side length
x² = 4²+5²
x² = 16+25
x² = 41
x = √41 or 6.4
These are not proportional to the triangle drawn, so the triangles are not similar.
For option C, our vertices are (-1, 1), (-1, 4) and (-7, 1). This makes the length of the horizontal segment 6 and the length of the vertical segment 3. This makes the missing side length
x² = 3²+6²
x² = 9+36
x² = 45
x = √45 or 3√5 or 6.7
These sides are not proportional to the sides of the triangle drawn, so the triangles are not similar.
For option D, our vertices are (-1, 1), (-1, 5) and (-7, 1). This makes the length of the horizontal segment 6 and the length of the vertical segment 4. This makes the missing side length
x² = 6²+4²
x² = 36+16
x² = 52
x = √52 or 2√13 or 7.21
These sides are all twice as long as the sides of the triangle drawn, this indicates that the triangles are similar. Therefore our answer is D.
