Answer:
No possible answer (unless the equal sign was supposed to be a plus sign, then see answer below)
Step-by-step explanation:
we can simplify the expression like such:
24 + 2x = 2x = 24
As you will notice 2x + 24 cannot equal 2x, or 24.
If the equals sign was a typo and was meant to be a plus sign then the answer is all real numbers.
2(12 + x) can be broken down to (2*12) + (2*x) which equals 2x + 24.
Then this equals the other side of the equation meaning that it doesn't matter what x equals the equation is always equal.

Answer:
x= 10, y= 6
Step-by-step explanation:
2x -3y= 2 -----(1)
-2x -y= -26 -----(2)
(1) +(2):
2x -3y -2x -y= 2 -26
-4y= -24
y= -24 ÷(-4)
y= 6
Substitute y= 6 into (1):
2x -3(6)= 2
2x -18= 2
2x= 18 +2
2x= 20
Divide both sides by 2:
x= 20 ÷2
x= 10
Line p contains point (6,-5) and is perpendicular to line q. The equation for line q is
y = 3x + 5.
Write an equation for line p.
Part I: Find the slope of line q. (1 point)
Part II: Find the slope of line p. (Write the negative reciprocal of the slope you found
in Part I.)
I just need the last part!!
Answer:
see explanation
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x + 5 ← is in slope- intercept form
with m = 3
Part 1
slope of line q is 3
Part 11
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{3}[/tex] = - [tex]\frac{1}{3}[/tex] ← slope of line p

What is the y-intercept of the line shown below?
A. 5
B. -5
C. 2
D. -2
Answer: -2
Step-by-step explanation: The y-intercept of a line is the point where the graph crosses or intersects the y-axis.
In this case, the line crosses the y-axis 2 units down from the
origin and we can write the coordinates of the point as (0, -2).
So the answer is -2.

The height of a ball in meters is modeled by fx 5x 2 50x, where x is the time in seconds after it is hit. How long is the ball in the air
Answer:
Equation is incorrect
Step-by-step explanation:
The equation is not written correctly. It is written with no arithmetic signs linking the expressions. One might assume it is f(x) = 5x^2 + 50x, but even so, something is still wrong.
The equation tells us that the ball will never return to the ground after it is hit. There are no nonzero positive values of time, x in seconds) for which this equation will produce the "0" for the height at ground level.

What is the slope of the line that passes through the points (6,2) and (-18. 2)?
Answer:
undefined
Step-by-step explanation:
slope of a line = m
m = (y1-y2) / (x1-x2)
m = (2-2) / (6 - -18)
m = 0 / (6+24)
m = 0/30
m = undefined
The slope of the line that passes through these two points is 0.
What is the slope of the line?If we know that a line passes through two points (a, b) and (c, d), then the slope is given by the following expression:
slope = (d - b)/(c - a)
Here the two points are (6, 2) and (-18, 2)
Then the slope is:
slope = (2 - 2)/(-18 - 6) = 0/-24 = 0
The slope is 0, so this is a horizontal line.

Emil would like to estimate the probability of 2 or more heads coming up in 3 coin flips. To do this, he has a computer randomly select 0 or 1 three times, with 0 representing heads and 1 representing tails. The results of 12 trials are shown in the table. 111 011 000 010 100 111 010 111 111 101 000 111 What is Emil's estimated probability, based on this simulation? Enter your answer as a fraction, in simplified form, in the box.
Probability helps us to know the chances of an event occurring. Emil's estimated probability, based on this simulation is 0.4167.
What is Probability?
The probability helps us to know the chances of an event occurring.
[tex]\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
As it is given that if the output of the computer is 1, then it represents tails, while the 0 represents the head. Also, the results of 12 trials are 111, 011, 000, 010, 100, 111, 010, 111, 111, 101, 000, 111.
Now, in the set of results, we need to calculate the number of results in which the outcome is 2 or more heads, therefore, we need the output that has 2 or more zeroes in it.
Results with 2 or more zeroes are 000, 010, 100, 010, 000
The number of results with 2 or more zeroes is 5.
The total number of possible results is 12.
The probability That Emil will get 2 or more heads can be written as,
[tex]\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
[tex]\rm Probability(2\ or\ more\ zero) = \dfrac{\text{Number of results with 2 or more zeroes }}{\text{Total number of possible results }}[/tex]
[tex]\rm Probability(2\ or\ more\ zero) = \dfrac{5}{12} = 0.4167 = 41.67\%[/tex]
Hence, Emil's estimated probability, based on this simulation is 0.4167.

Chris ate 1/8 of a banana cream pie with a 14 inch diameter. What is the area of the remaining portion of the pie? Round to the nearest tenth. Use 3.14 for pi.
Answer:
Area of a circle is pi x radius squared.
If we use 3.14 for pi, and the Diameter is 14 so that radius will be 7 (half of diameter), this means we have 3.14 x 7 squared = 153.86.
Total area of pie is 153.86.
If 1/8 was eaten that means 7/8 are left.
153.86/8= 19.23
19.23 x 7 = 134.6 to the nearest tenth..
For a Valentine's Day dance, tickets for couples cost $12 and tickets for individuals cost $8. Suppose 250 students attended the dance, and $1580 was collected from ticket sales. How many of each type of ticket was sold?
PLEASE DO THIS IN ELIMINATION OR GRAPHING METHOD (NOT substitution method, as I already did it like this)
Answer: 105 couple tickets and 40 individual tickets
For this I will use the "Graphing Method"
First, we need to set up two equations.
-> Let x be the number of couple tickets.
-> Let y be the number of individual tickets.
-> It is "2x" because a couple means two.
$12x + $8y = $1,580
2x + y = 250
Next, we will graph this.
-> The point at which the two lines intersect is our solution.
-> See attached.
-> x = 105, so 105 couple tickets
-> y = 40, so 40 individual tickets
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.
- Heather
Answer:
Step-by-step explanation:
Let's imagine if all the tickets were for individuals
The cost would be 250 x $8 = $2000
That is $420 higher than the actual cost.
The difference between a ticket for couples and a ticket for individuals is $4
Then, we can conclude that there are 420 : 4 = 105 couple tickets that were sold.
And, 40 individual tickets that were sold
The reason why we have 420:4 is because at the start, we assume every ticket was individuals. On the process, we replace one individual ticket by a couple ticket, keep replacing until the gap is exactly 420.
Hope this helps :)
The sum of the square of a positive number and the square of 2 more than the number is 20. What is the number?
Answer:
Let one number = x
Let the other number = x + 2
Use these variables to establish appropriate equations.
x2 + (x + 2)2 = 52
Solve for x from this equation. Expand any terms to get rid of parentheses.
x2 + x2 + 4x + 4 = 52
Combine any like terms.
2x2 + 4x - 48 = 0
WE now have a quadratic equation. Factor out a 2.
2(x2 + 2x - 24) = 0
Factor completely.
2(x + 6)(x - 4) = 0
Set the binomial factors equal to zero.
x + 6 = 0 and x - 4 = 0
Solve for x from these parts. Choose the positive x value.

What is the maximum value of P = 24x + 30y, given the constraints on x and y listed below?
Answer:
Answer:So the maximum value of P is 138.Step-by-step explanation:
P(0,0)= 24(0) + 30(0) =0
P(0,1)= 24(0) + 30(1) =30
P(5,0)= 24(5) + 30(0) =120
P(2,3) =24(2) + 30(3) = 138I also
If the linear equation is P = 24x + 30y. Then the maximum value of the linear equation P is 138.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
The maximum value of P = 24x + 30y will be
P(0,0)= 24(0) + 30(0) =0
P(0,1)= 24(0) + 30(1) =30
P(5,0)= 24(5) + 30(0) =120
P(2,3) =24(2) + 30(3) = 138
