Step-by-step explanation:
The answers is A
The required equation of the parallel track that runs through the point (4 , -2) is 2x + 5y = −2.
The engineers designing the All Aboard Railroad between Boca Raton and Jupiter decided to create parallel tracks through this portion of the railway.The southbound track will have an equation of 2x + 5y = 15. What is the equation of the parallel northbound track that runs through the point (4, – 2) TO determine.
The equation is the relationship between variables and represented as y=ax + b is an example of a polynomial equation.
Equation of the southbound track,
2x + 5y = 15
slope of the above equation is m = -2/5
Since the slope of the parallel lines are equal.
The equation of the parallel northbound track that runs through the point (4, – 2),
(y + 2) = -2/5 (x - 4)
5(y + 2) = -2 (x-4)
5y + 10 = - 2x +8
2x + 5y = 8-10
2x + 5y = -2
Thus, the required equation of the parallel track that runs through the point (4 , -2) is 2x + 5y = −2.

Answer:
x = 15°
Step-by-step explanation:
∠2 and ∠4 are same-side interior angles, meaning they add up to 180
2x + 10 + 4x + 80 = 180
Rearrange (collect like terms)
6x = 180 - 80 - 10
6x = 90
x = 15°
Answer:
x = 15Step-by-step explanation:
∠2 = 2x + 10
∠4 = 4x + 80
∠2 and ∠4 are supplementary angles, this mean ∠2 + ∠4 = 180
2x + 10 + 4x + 80 = 180
combine similar terms: 6x = 180 - 80 - 10
simplify: 6x = 90
solve for x = 90 / 6
x = 15
A line passes through the points (3, 5) and (2, 0). What is the slope?
Answer:
y= -4x - 5
Step-by-step explanation:
5 is your y-intercept
The slope of the line which passes through the points (3,5) and (2,0) is 5
From the question,
We are to determine the slope of the line
The slope of a line with two given points can be determined from the formula
[tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
Where m represents the slope
From the given information
x₁ = 3
y₁ = 5
x₂ = 2
y₂ = 0
Putting these into the formula,
We get
[tex]m = \frac{0-5}{2-3}[/tex]
Then,
[tex]m = \frac{-5}{-1}[/tex]
∴ m = 5
Hence, the slope of the line which passes through the points (3,5) and (2,0) is 5

If n divided by m equals 7/8,
what does m divided by n equal?
Step-by-step explanation:
1,
It is found that m divided by n is equal to 8/7.
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.
Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.
Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
Thus, a/ b = a divided in b equal parts.
If n divided by m equals 7/8, then m divided by n equal.
n / m = 7/8
Then m/n = 8/7
Therefore, m divided by n is equal to 8/7.

open the parenthesis
8x - 8 + 2 = 4x - 8
add 8 to both sides of the equation
8x - 8 + 2 + 8 = 4x - 8 + 8
combine like terms
8x + 2 = 4x
subtract 4x from both sides of the equation
8x - 4x + 2 = 0
4x + 2 = 0
subtract 2 from both sides of the equation
4x + 2 - 2 = 0 -2
4x = -2
divide both sides by 4

Find the equation of line b described below, in slope-intercept form
Line a is perpendicular to line b
Line a passes through the points (1,-8) and (9,-12)
Line b passes through the point (-8, -16)
The equation of line b is y= ______
Given:
Line a is perpendicular to line b .
Line a passes through the points (1,-8) and (9,-12) .
Line b passes through the point (-8, -16).
To find:
The equation of b.
Solution:
Line a passes through the points (1,-8) and (9,-12) . So, slope of line a is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m_a=\dfrac{-12-(-8)}{9-1}[/tex]
[tex]m_a=\dfrac{-12+8}{8}[/tex]
[tex]m_a=\dfrac{-4}{8}[/tex]
[tex]m_a=-\dfrac{1}{2}[/tex]
Product of slopes of two perpendicular lines is -1.
[tex]m_a\times a_b=-1[/tex]
[tex]-\dfrac{1}{2}\times a_b=-1[/tex]
[tex]b=2[/tex]
Slope of line b is 2.
If a line passing through a point [tex](x_1,y_1)[/tex] with slope m, then equation of line is
[tex]y-y_1=m(x-x_1)[/tex]
Line b passing through (-8,-16) with slope 2. So, equation of line b is
[tex]y-(-16)=2(x-(-8))[/tex]
[tex]y+16=2(x+8)[/tex]
[tex]y+16=2x+16[/tex]
Subtract 16 from both sides.
[tex]y=2x[/tex]
Therefore, the equation of line b is [tex]y=2x[/tex].

so find how many numbers there are
- 13
the middle number of 13 is 7
so the 7th number should be the median of this sum
7th number - 46
Answer - 46
Hope you understand
:-)
The data given results in this list
{23,27, 32,32,36,36, 46,49, 51,55,58,59, 63}
The middle most value is 46 since there are 6 items below it {23,27,32,32,36,36} and 6 items above it {49,51,55,58,59,63}.
It might help to cross off the outer values and work your way in so you can spot the middle value easier.
