The product of 3 consecutive odd numbers is 2,145. Enter a simplified expression for finding the numbers. Let n be the first odd number.
Answer:
11, 13 and 15.
Step-by-step explanation:
Let's say that the odd number is "x". If x is for example 15, then the next ODD number would be 15+2=17 and the one after that would be 15+2+2=15+4=19.
Applying that here, we get:
Odd number* the next odd number*the next odd number=2145
x*(x+2)*(x+4)=2145
x*(x^2+4x+2x+8)=2145
x^3+6x^2+8x=2145
By solving the polynomial, you get x=11.
Which makes our three numbers: 11, 13 and 15.
11*13*15=2145. The answer checks.
Final answer:
To find the three consecutive odd numbers whose product is 2,145, set up and solve an equation for n, the first odd number. The solution is n = 11, so the three consecutive odd numbers are 11, 13, and 15.
Explanation:
To find the three consecutive odd numbers whose product is 2,145, we can set up an equation and solve for n, the first odd number:
Let n be the first odd number
Then, the next two consecutive odd numbers would be n + 2 and n + 4
We can write the equation as: n x (n + 2) x (n + 4) = 2,145
Expanding this equation, we have: n³ + 6n² + 8n - 2,145 = 0
By factoring or using a numerical method, we can find that n = 11
So, the three consecutive odd numbers are 11, 13, and 15.

Answer:
Part A) The percentage increase was [tex]6.1\%[/tex]
Part B) Michael is financially better off this year than last year
Step-by-step explanation:
Part A)
we know that
Using proportion
Let
x-----> the percentage increase
[tex]\frac{100\%}{33,000}=\frac{x\%}{35,000-33,000}\\ \\x=2,000*100\%/33,000\\ \\x=6.1\%[/tex]
Part B) Compare the percentage increase with the inflation
[tex]6.1\%>5\%[/tex]
The percentage increase is greater than the inflation

Find the equation of the line that passes through the point (−3, −4) and is parallel to the line that passes through the points (−5, 1) and (7, −3).
Answer:
[tex]y = -\frac{1}{3}x - 5[/tex]
Step-by-step explanation:
To write the equation of a line use the point slope formula [tex]y - y_1 = m(x-x_1)[/tex]. Find m by using the slope formula with the points.
[tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{1--3}{-5-7} =\frac{4}{-12} =-\frac{1}{3}[/tex]
Since the line is parallel, it will have the same slope.
Substitute m = -1/3 and (-3,-4).
[tex]y --4 = -\frac{1}{3}(x --3)\\y + 4 = -\frac{1}{3}(x+3)\\y +4 = -\frac{1}{3}x - 1\\y = -\frac{1}{3}x - 5[/tex]
Final answer:
The equation of the line that passes through the point (-3, -4) and is parallel to a given line is y = -1/3x - 5. This is found by calculating the slope of the given line and then using the point-slope form to find the equation for the parallel line.
Explanation:
The student has asked for the equation of a line that passes through point
(-3, -4) and is parallel to another line. First, we need to find the slope of the given line that passes through points (-5, 1) and (7, -3). The slope (m) is calculated by using the difference in y-coordinates over the difference in x-coordinates (rise over run), which is:
m = (y2 - y1) / (x2 - x1) = (-3 - 1) / (7 - (-5))
m = (-4) / (12) = -1/3
Since parallel lines have the same slope, our new line will also have a slope of -1/3. Using the point-slope form of a line's equation, y - y1 = m(x - x1), and substituting the point (-3, -4) and the slope -1/3, we get the equation of the parallel line:
y - (-4) = -1/3(x - (-3))
y + 4 = -1/3(x + 3)
To write it in slope-intercept form (y = mx + b), we distribute the slope and simplify:
y + 4 = -1/3x - 1
y = -1/3x - 5
Therefore, the equation of the line parallel to the given line and passing through the point (-3, -4) is y = -1/3x - 5.

which functions are symmetric with respect to the y axis
Answer:
A, B, and D
Step-by-step explanation:
Only the functions that have x by itself between the absolute value signs (A, B, and D) are symmetric with respect to the y-axis .
Placing a constant outside the absolute value signs moves the function up or down the y-axis but retains the symmetry.
Adding a constant inside the absolute value signs (as in C and E) moves the axis of symmetry to the left or right of the y-axis.
In the diagram, both A and B are symmetric with respect to the y-axis, but C has been shifted three units to the left.

A supersonic jet was flying at a constant velocity starting 8,400 kilometers west of U.S. airspace. It
flew one-third of the way to US, airspace in 2 hours. What was the jet's velocity?
Write your answer as a whole number. blank
kilometers per hour to the east
Submit
9514 1404 393
Answer:
1400 km/hour to the east
Step-by-step explanation:
We assume the jet is flying directly toward US airspace, so is flying east. The speed is ...
speed = distance/time
speed = ((8400 km)/3)/(2 h) = 1400 km/h
The jet's velocity is 1400 km per hour to the east.
Final answer:
The velocity of the supersonic jet traveling one-third of the way to U.S. airspace is 1400 km/h to the east, calculated by dividing the distance covered (2800 km) by the time taken (2 hours).
Explanation:
The supersonic jet's velocity can be determined by calculating the distance it flew and the time taken to cover that distance. The jet started 8400 km west of U.S. airspace and flew one-third of that distance, which is 2800 km (8400 km / 3). It took 2 hours for the jet to cover this distance. So, to find the velocity, we use the formula velocity = distance / time.
V = 2800 km / 2 hours = 1400 km/h to the east.

A bag contains 4 red, 3 yellow, 3 blue, and 2 white marbles, for a total of 12 marbles. If Lucia randomly picks two marbles from the bag without putting the first marble back, what is the probability that the first marble is red and the second is white?
Answer choices:
A. 2/144
B. 3/144
C. 2/33
D. 2/12
Answer: 2/33 hoped this helped you
Step-by-step explanation:
The probability that Lucia picks a red marble first and a white marble second from the bag without replacement is
2 / 33, found by multiplying the individual probabilities of each event. Hence option C is correct.
The question asks about the probability that Lucia randomly picks a red marble first and a white marble second from a bag containing marbles of various colors, without replacement. To calculate this probability, we need to consider the total number of marbles and the number of favorable outcomes for both events happening consecutively.
With 4 red and 2 white marbles in the bag, the probability of picking a red marble first is
P(Red) = Number of red marbles / Total number of marbles
P(Red) = 4 / 12 = 1 / 3
After picking a red marble, there are 11 marbles left, including 2 white marbles. The probability of then picking a white marble is
P(White | Red) = Number of white marbles / Total number of marbles remaining
P(White | Red) = 2 / 11
The combined probability is then the product of the two individual probabilities:
P(Red and White) = P(Red) X P(White | Red)
P(Red and White) = (4 / 12) X (2 / 11)
P(Red and White) = 8 / 132 = 2 / 33.
Thus, the correct answer is 2 / 33, which corresponds to option C.
Which number line represents the solution set for the inequality –x ≥ 4?
Answer:
I decided to draw it since you didnt provide a pic.....
so here:
Step-by-step explanation:
STEPS:
–x ≥ 4
÷-1 ÷-1
x ≤ -4
Final answer:
The solution set for the inequality -x ≥ 4 is x ≤ -4. On a number line, this is represented by a solid dot at -4 and a line extending to the left.
Explanation:
To find the number line that represents the solution set for the inequality
-u2061x
≥ 4, we first need to solve the inequality for x. By dividing each side of the inequality by -1 (and remembering to flip the inequality sign because we're dividing by a negative number), we get x
≤ -4. This means all numbers less than or equal to -4 are part of the solution set.
On a number line, this would be represented by a solid dot at -4 (to include -4 itself) and a line extending to the left to indicate all numbers less than -4 are included.
