Answer:
Fourth answer choice.
Step-by-step explanation:
Start by factoring the numerator and the denominator:
(x - 1)(x + 1)
-----------------
(x + 1)(x + 4)
Note that x can be neither -1 nor -4, since either results in an undefined quotient. These two x-values are critical values because of this. If we cancel the (x + 1) terms, we obtain the result
(x - 1)
--------- for x ≠ -1 and x ≠ - 4
(x + 4)
The next step is to evaluate the given quotient on the three intervals defined by {-4, -1}: (-∞, -4), (-4, -1), (-1, ∞ ). We choose an x-value from within each interval and evaluate the given function at each. Suitable test values include {-10, -3, 0}:
At x = -10, the reduced given quotient (x - 1) / (x + 4) takes on the value (-10 - 1) / (-10 + 4) = -11/(-6), which is positive. Reject this interval, as we want and expect the quotient value to be 0 or less.
At x = -3, we get (-3 - 1) / (-3 + 4), which is negative. The given inequality is true on the interval (-4, -1) (or -4 < x < -1).
At x = 0, we get (0 - 1) / (0 + 4), which is negative, so the inequality is true on (-1, ∞ ).
So the fourth answer choice is the correct one.

The value of b which satisfies the given quadratic equation is both: A. b = (-3 + 2√3)/2 and (-3 - 2√3)/2.
How to solve a quadratic equation?
In this exercise, you're required to solve for the value of b which satisfies the given quadratic equation. Thus, we would simplify the quadratic equation as follows:
3(2b + 3)² = 36
Dividing both sides by 3, we have:
(2b + 3)² = 12
Taking the square root of both sides, we have:
2b + 3 = ±√12
2b + 3 = ±√4 × √3
2b + 3 = ±2√3
2b = -3 ± 2√3
b = (-3 + 2√3)/2 and (-3 - 2√3)/2.

If the trapezoid below is reflected across the x-axis, what are the coordinates
of B?
A. (4-8)
B.(-4,-8)
C. (-4,8)
D. ( -8,-4)
Answers
As you may have intentionally forgotten to add the diagram. The diagram of the trapezoid is attached below.
Answer:
The point B(4, 8) after reflection across x-axis would be B'(4, -8).
B(4, 8) → B'(4, 8)
Step-by-step explanation:
The rule of reflection across the x-axis states that a reflection of a point, let say M(x, y), across the x-axis does not change the value of x-coordinate but changes the sign of the y-coordinate of the point.
In a nutshell,
The point M(x, y) after reflection across x-axis would be M'(x, -y)
M(x, y) → M'(x, -y)
From the diagram attached below, the coordinate of point B is (4, 8).
So, according to the rule of reflection across the x-axis, the coordinates of the image of the point B (4, 8) after the reflection across the x-axis will be B'(4, -8).
i.e.
The point B(4, 8) after reflection across x-axis would be B'(4, -8).
B(4, 8) → B'(4, 8)

if measure angle MPL=63 HOW COULD I FIND THE OTHERS?
Answers
answer:
JK = 27
NJ = 153
JL = 117
KNM = N/A
MJL = N/A
JLK = N/A
step-by-step explanation:
you can see there are pairs of vertical angles which means they would be equalremember a circle adds up to 360the arc's measure and the angle's measure would be equalsince we know ∠MPL is 63°, and ∠KPL is 90°, we can find the others too∠NPM + ∠MPL = 90
∠NPM + 63 = 90
∠NPM = 27°
so, ∠JPK = 27° (since they are vertical angles)
now, add up all the ones you know to find the other angle63 + 90 + 27 + 27 + X = 360
let x be the missing angle63 + 90 + 27 + 27 + X = 360
207 + X = 360
X = 153
so, ∠JPN = 153°
now put the measures of the arcsARCS:
JK = 27
NJ = 153
JL = 117
KNM = N/A
MJL = N/A
JLK = N/A
- sorry this is the furthest i can help, i have only learnt up to that so do not know how to find the rest.
using the relationship between intercepted arc and central angle, the missing measures are:
a. m(JK) = 27°
b. m(NJ) = 153°
c. m(JL) = 117°
d. m(KNM) = 207°
e. m(MJL) = 297°
f. m(JLK) = 333°
Central Angle and measure of Intercepted ArcThe central angle is always equal to the measure of the intercepted arc.A full circle = 360 degrees.Half circle = 180 degrees.Given:
m∠MPL = 63°
a. m(JK) = 180 - 90 - 63 = 27°
m(JK) = 27°
b. m(NJ) = 180 - m(JK)
m(NJ) = 180 - 27
m(NJ) = 153°
c. m(JL) = 90 + 27
m(JL) = 117°
d. m(KNM) = 180 + 27
m(KNM) = 207°
e. m(MJL) = 27 + 180 + 90 = 297°
f. m(JLK) = 360 - 27
m(JLK) = 333°
Therefore, using the relationship between intercepted arc and central angle, the missing measures are:
a. m(JK) = 27°
b. m(NJ) = 153°
c. m(JL) = 117°
d. m(KNM) = 207°
e. m(MJL) = 297°

n a drawer, there are 12 pairs of socks, 6 of which are white. If you randomly select two pairs of socks, what is the probability that both are white? Express your answer as a reduced fraction.
Answers
The probability that both pairs of socks selected from a drawer containing 12 pairs, 6 of which are white, are white, is 5 out of 22.
Explanation:The subject of this question is the probability in mathematics, specifically dealing with combinations. In the problem, there are 12 pairs of socks and 6 of them are white. When we are drawing two pairs, we want both to be white which defines our event space.
To find the answer, we need to divide the number of favorable outcomes by the total number of outcomes. The favorable outcome is the probability of choosing 2 white socks out of 6 which can be calculated by combinations (represented by the formula C(n, k) = n! / [k!(n - k)!]). So, C(6, 2) = {6! / [2!(6 - 2)!]} = 15.
The total number of outcomes is the number of ways to pick 2 pairs out of 12, calculated by combinations as well, C(12, 2) = {12! / [2!(12 - 2)!]} = 66.
Now, the probability is favorable outcomes divided by total outcomes = 15/66 = 5/22.

________+ 1 1/10=3 1/2
Answers
Answer: 12/5 or 2 2/5
Step-by-step explanation:
From the question: ________+ 1 1/10=3 1/2
Let the missing value be x
Convert the improper fraction to proper fraction
1 1/10 = 11/10
3 1/2= 7 /2
Therefore, x + 11/10 = 7/2
Subtract both sides of the equation by 11/10 to get the value of x
x + 11/10 - 11/10 = 7/2 - 11/10
x = 24/10
x = 12/5 or 2 2/5
Answer:
2.4 or 2 2/5
Step-by-step explanation:
1. Creating the Equation
This problem is meant to have you work backwards from the information given. In this case, there is no reason to organize information, as this is not a word problem.
Instead, a simpler approach would be to replace the blank space with the variable x.
Once x replaces the blank space, the equation should appear as shown:
x + 1 1/10 = 3 1/2
2. Solving for x
Now that the equation was created, use the order of operations to solve for x.
Firstly, convert all the mixed numbers into improper fractions to simplify the solving process.
x + 11/10 = 7/2
Next, convert the 7/2 fraction into the same denominator as the 11/10 fraction. To do this, multiply both the numerator and the denominator by 5/5.
x + 11/10 = 7/2
x + 11/10 = 5/5(7/2)
x + 11/10 = 35/10
Finally, subtract the 11/10 fraction from both sides of the equation to find the solution to x.
x + 11/10 = 35/10
x + 11/10 - 11/10 = 35/10 - 11/10
x = 24/10
x = 2 4/10
(Simplify the fraction if needed)
x = 2 2/5
As said earlier, x was meant to represent the final answer.
x + 1 1/10 = 3 1/2
x = 2 2/5
2 2/5 + 1 1/10 = 3 1/2

Find the value of x in the figure.
Answers
Answer:
x = 27
Step-by-step explanation:
Using the information in the figure, we can conclude that the 3x - 17, x + 40, and 2x - 5 would be the measures of the three interior angles of the triangle. The sum of the interior angles of a triangle is 180° (use the equation: (n-2) × 180°).
By using this information, we can conclude that (3x - 17) + (x + 40) + (2x - 5) would equal 180. We can put this into the equation:
(3x - 17) + (x + 40) + (2x - 5) = 180
To find the value of x in this equation (solve for x), we would have to get the equation into the form x = _.
(3x - 17) + (x + 40) + (2x - 5) = 180
3x - 17 + x + 40 + 2x - 5 = 180
Combine like terms.
6x + 18 = 180
Subtract 18 from both sides to get rid of the +18 on the left side.
6x = 180 - 18
Simplify.
6x = 162
Divide 6 form both sides to get rid of the coefficient of 6 on the left side.
x = 162 ÷ 6
Simplify.
x = 27
x = 27

The student's question asks us to find the product of 3 and the expression 2y - 4x = 8. Multiplying both sides of the equation by 3 we get:
3 * (2y - 4x) = 3 * 86y - 12x = 24The product of 3 with each term on the left side of the equation has been calculated, resulting in a new equation: 6y - 12x = 24. It is important to carry out the multiplication operation carefully, ensuring that each term within the parentheses is multiplied by 3.

A gray wolf's sperm contains
39 chromosomes. He mates with a female gray wolf.
How many chromosomes will there be in the resulting zygote?
Answers
Answer:
The resulting zygote will have 78 chromosomes.
Step-by-step explanation:
The sperm and eggs are the sex cells of animals. These cells contain half the number of chromosomes compared to the number of chromosomes present in the somatic cell of that particular organism.
When the sperm and the egg cell unite to form a zygote, the 39 chromosomes in the wolf's sperm and the 39 chromosomes in the female wolf's egg will add up to male 78 chromosomes in the zygote.
In the process of sexual reproduction in wolves, each parent contributes 39 chromosomes. So, a zygote formed from the sperm of a male wolf and the egg of a female wolf will contain a total of 78 chromosomes.
Explanation:The concept is related to the process of sexual reproduction in mammals, which includes wolves. Since the process of sexual reproduction involves the combination of both parents' genetic material, each parent contributes half the total number of chromosomes in a zygote.
In the case of a gray wolf, the sperm contains 39 chromosomes. Therefore, the egg from the female gray wolf will also contain 39 chromosomes. When the sperm and egg meet during fertilization, they combine to form a zygote containing a total of 78 chromosomes — 39 from the male and 39 from the female.
