Pls mark brainliest :)
The temperature of the day is 17 degrees Fahrenheit.
Given data:
To find the high temperature of the day, add the temperature difference to the current temperature.
The temperature difference is 29 degrees Fahrenheit below the high temperature of the day.
Given that the current temperature is 12 degrees Fahrenheit below zero, determine the high temperature by adding the temperature difference:
High temperature = Current temperature + Temperature difference
On simplifying the equation:
High temperature = -12 degrees Fahrenheit + 29 degrees Fahrenheit
High temperature = 17 degrees Fahrenheit
Hence, the high temperature for the day is 17 degrees Fahrenheit.
The correct answer is B. 17 degrees Fahrenheit.

In the xy-coordinate plane shown below, point P has coordinates (8,-6). Which
of the following is an equation of the line that contains points O and P?
a. y = -x + 4
b. y = -x
c. y = x - 4
d. y=-3X
The answer will be D
The equation of the line passing through points O(0,0) and P(8,-6) is y = -3/4x.
Explanation:To find the equation of a line, we need to determine its slope and y-intercept. The slope can be found using the formula (y2 - y1) / (x2 - x1) where (x1, y1) and (x2, y2) are coordinates of two points on the line. In this case, we have the coordinates of points O and P: O(0,0) and P(8,-6).
The slope of the line passing through O and P is (-6 - 0) / (8 - 0) = -6 / 8 = -3 / 4.
Since the line passes through the origin (0,0), its y-intercept is 0. Therefore, the equation of the line is y = -3/4x.

x + y = 14 and x - y = 2
x + y = 14 and y - x = 2
Answer:
B. x + y = 14 and x - y = 2
Step-by-step explanation:
Sum means addition, so the sum of the tens digit (x) and the ones digit (y) is equal to 14 (x + y = 14).
Difference means subtraction, so the difference between the tens digit (x) and the ones digit (y) is 2 (x - y = 2).

Answer:
p = 1/6
Step-by-step explanation:
5/6 - 1/3 n = p(5-2n)
Multiply each side by 6 so we do not have any fractions
6(5/6 - 1/3 n) = 6*p(5-2n)
5 - 2n = 6p (5-2n)
Divide each side by (5-2n) to isolate 6p
(5-2n)/(5-2n) = 6p (5-2n)/ (5-2n)
1 = 6p
Now divide by 6 to get p alone
1/6 = 6p/6
1/6 = p

the table represent the consumer price index for a basket of goods and services for 3 consecutive years. calculate the inflation rate for 2014.
We'll assume that the CPI is given for the END of the year.
Then 2014's rate is the change in price from 2013 in percent,
r = 180/125 - 1 = 36/25 - 1 = 11/25 = 44 %
Answer: choice c
----------
This is a pretty poor question. The questioner should clarify the exact dates of the given values of the CPI, and use the actual values. 44% is an alarming inflation rate, but fortunately a fictitious one here in the US. US inflation in 2014 was around 0.7% so the number the student was asked to compute was off by more than a factor of sixty.

An ellipse has a vertex at (0, -7), a co-vertex at (4,0), and a center at the origin. Which is the equation of the ellipse in standard form?
ANSWER
[tex]\frac{ {y}^{2} }{49} + \frac{ {x}^{2} }{ 16 } = 1[/tex]
EXPLANATION
The given ellipse has a vertex at (0, -7), a co-vertex at (4,0), and a center at the origin.
The equation of an ellipse with vertex on the y-axis and center at the origin is given by
[tex]\frac{ {y}^{2} }{a ^{2} } + \frac{ {x}^{2} }{ {b}^{2} } = 1[/tex]
[tex]\frac{ {y}^{2} }{( - 7) ^{2} } + \frac{ {x}^{2} }{ {4}^{2} } = 1[/tex]
[tex]\frac{ {y}^{2} }{49} + \frac{ {x}^{2} }{ 16 } = 1[/tex]
The equation of the ellipse with a vertex at (0, -7), a co-vertex at (4,0), and a center at the origin is x^2/16 + y^2/49 = 1.
Explanation:To find the equation of the ellipse in standard form, we need to identify the lengths of the major and minor axes. The given vertex at (0, -7) indicates that the semi-major axis length, a, is 7 because the distance from the center to a vertex measures the semi-major axis. Similarly, the co-vertex at (4, 0) represents the semi-minor axis length, b, which is 4.
Since the center is at the origin (0, 0), the standard form of the ellipse equation is given by x^2/b^2 + y^2/a^2 = 1. Plugging the values of a and b, we get x^2/4^2 + y^2/7^2 = 1. So, the equation of the ellipse is x^2/16 + y^2/49 = 1.

Step-by-step explanation:
Final answer:
Mary spends a total of 24 hours on math and art homework combined over a period of 4 weeks.
Explanation:
Mary spends 2 2/3 hours on math homework and 3 1/3 hours on art homework each week.
To find out how much time she spends on both subjects over 4 weeks, first, we add the weekly hours:
2 2/3 + 3 1/3 = 6 hours per week.
Next, we multiply this weekly total by 4 to determine the monthly total: 6 hours/week × 4 weeks = 24 hours.
Therefore, Mary spends a total of 24 hours on math and art homework over 4 weeks.

[tex]\left[\begin{array}{ccc}7\\4\\2\end{array}\right][/tex]
The answer is a single-column matrix (7,4,2)
Step-by-step explanation:
In such multiplication of matrices, you have to proceed by multiplying each ROW of the first matrix by the COLUMN of the second matrix. So,
[tex]\left[\begin{array}{ccc}3&6&1\end{array}\right] * \left[\begin{array}{ccc}2\\0\\1\end{array}\right] = (3 * 2) + (6 * 0) + (1 * 1) = 6 + 0 + 1 = 7[/tex]
then...
[tex]\left[\begin{array}{ccc}2&4&0\end{array}\right] * \left[\begin{array}{ccc}2\\0\\1\end{array}\right] = (2 * 2) + (4 * 0) + (0 * 1) = 4 + 0 + 0 = 4[/tex]
and
[tex]\left[\begin{array}{ccc}0&6&2\end{array}\right] * \left[\begin{array}{ccc}2\\0\\1\end{array}\right] = (0 * 2) + (6 * 0) + (2 * 1) = 0 + 0 + 2= 2[/tex]

anyone know how to do dis?!?!
Answer:
{-8, 8}
Step-by-step explanation:
Simplify 7· |n| = 56 by dividing both sides by 7:
|n| = 8
Because this is an absolute value equation, there are two separate solutions. One is n = +8 and the other is n = -8.
There are two solutions.
[tex]
7\times\mid n\mid=56\Longrightarrow\mid7n\mid=56 \\
\mid7\times x_1\mid=56\Longrightarrow x_1=\frac{56}{7}=\boxed{8} \\
\mid7\times(-x_1)\mid=56\Longrightarrow-x_2=\frac{56}{7}\Longrightarrow x_2=\boxed{-8}

Post A and Post B are 120 meters apart. Post B and Post C are 300 meters apart. Ben cycled from Post A to Post B in 15 seconds. Then he cycled from Post B to Post C in 55 seconds. Find Ben's average speed for the distance from post A to Post C.
Show work
Answer: 6 meters per second
Step-by-step explanation:
Ben's average speed from Post A to Post C is 6 meters per second, calculated by dividing the total distance cycled (420 meters) by the total time taken (70 seconds).
Explanation:The subject of the problem is calculating average speed. In this context, Ben's average speed can be calculated by dividing the total distance cycled by the total time taken.
Total distance is the sum of the distance from Post A to Post B and from Post B to Post C, which is 120 meters + 300 meters = 420 meters.
Total time is the sum of the time taken from Post A to Post B and from Post B to Post C, which is 15 seconds + 55 seconds = 70 seconds.
So, Ben's average speed=Total Distance/Total Time.
This equals 420 meters/70 seconds= 6 meters/second.
Therefore, Ben’s average speed for the entire distance from Post A to Post C is 6 meters per second.

Consider the following equation. 6 ^ ( -x ) + 4 = 3x -1
Answer:
1.68
Step-by-step explanation:
1. Move all of the terms to the left side and set the problem equal to zero.
2. Set each factor equal to zero.
For this case we have the following equation:
[tex]6 ^ {- x} + 4 = 3x-1[/tex]
We must clear the value of x, we follow the steps below:
We subtract 3x on both sides of the equation:[tex]6 ^ {- x} -3x + 4 = -1[/tex]
Add 1 to both sides of the equation:
[tex]6 ^ {- x} - 3x + 4 + 1 = -1 + 1\\6 ^ {- x} - 3x + 5 = 0[/tex]
Each side of the equation is drawn, then the solution is the x value of the intersection point.

create an expression to represent the number of eggs Ty has left.
[tex]10-4n=x[/tex]
Hope this helps.
Brainliest would help me as well.
Final answer:
The number of eggs Ty has left after making 4 servings of scrambled eggs, using n eggs for each serving, is represented by the algebraic expression 10 - 4n.
Explanation:
To determine the number of eggs Ty has left after making scrambled eggs, we need to use a simple algebraic expression. If Ty started with 10 eggs and used n eggs for each of the 4 servings, we can represent the number of eggs used in total as 4n.
To find the number of eggs remaining, we subtract the total number of eggs used from the initial number of eggs:
Number of eggs remaining = Initial number of eggs - Number of eggs used
Number of eggs remaining = 10 - 4n
