12-5x-4kx=y solve for x

Answers

Answer 1
12 - 5x - 4kx = y.....subtract 12 from each side
-5x - 4kx = y - 12....factor out x on the left
x(-5 - 4k) = y - 12 ...divide both sides by -5 - 4k
x = (y - 12) / (-5 - 4k) or x = (-y + 12) / (4k + 5) <==
Answer 2
[tex]12-5x-4kx=y :x[/tex] 

[tex]-5x-4kx=y-12[/tex] 

[tex]-x(5+4k)=y-12 [/tex] 

[tex]-x= \dfrac{y-12}{5+4k} [/tex] 

[tex]x=- \dfrac{y-12}{5+4k}[/tex]

The coordinates of the points M, N, P, and Q are -11, 32, -15, and 17, respectively. Which point is closest to the origin? M N P Q

Answers

to find what is closest to the origin (0), we must take the absolute value of these numbers.

M : | -11 | = 11 spaces from 0
N : | 32 | = 32 spaces from 0
P : | -15 | = 15 spaces from 0
Q : | 17 | = 17 spaces from 0

so the point closest to the origin (0) is going to be point M
M is the closest to the origin

Given that the legs of a right triangle measure a and b and the hypotenuse of the triangle measures c, what does the Pythagorean Theorem state about the sides of this triangle? a2 + c2 = b2 a2 − b2 = c2 2a + 2b = 2c a2 + b2 = c2

Answers

The Pythagorean Theorem is a^2+b^2 = c^2 which can be written as [tex]a^2 + b^2 = c^2[/tex]

The longest side (c) is always on its own side. This says "the squares of 'a' and 'b' add up to the square of 'c' "

The Pythagorean Theorem establishes the relationship between the sides of a right triangle, highlighting that the sum of the squares of the two shorter sides equals the square of the hypotenuse.

The Pythagorean Theorem states that in a right triangle, the sum of the squares of the two shorter sides (legs) is equal to the square of the longest side (hypotenuse). In mathematical terms, it is represented as a² + b² = c². This relationship applies to all right triangles and is fundamental in geometry.

She drives at an average speed of 60 miles per hour.

She leaves Rotherham at 7:30 am.
Does she arrive in London before 10:00 am?

Please show all of your working out.

Answers

No. See, you can take 60 out of 156 twice and you are left with 36. This means the drive would take about 2 hours and 36 minuets. 7+2=9 30+36=66 so then you add an our the time and you get that she would arrive a few minuets afterwards. (I'm sorry if I didn't explain this very well)

Answer:

No, she will not arrive  London before 10:00 am.

Step-by-step explanation:

It is given that:

Kim drives 156 miles from Rotherham to London.

She drives at an average speed of 60 miles per hour.

i.e. in one hour she drives 60 miles.

Hence she covers 1 mile in 1/60 hours.

Now she has to travel 156 miles.

i.e. it takes her:

156/60 hours=2.6 hours.

i.e. it takes her 2 hours and 36 minutes to reach from Rotherham to London.

(

since 0.6 hours=36 minutes.

As 1 hour= 60 minutes.

so, 0.6 hours=0.6×60=36 minutes ).

Hence, if she start from Rotherham at 7:30 am.

Then she will reach London at:

7:30+2.6=10:06 am.

Hence, she will reach London after 10 am.

There are students in three rows taking a test. there are 22 students in the first row, 19 students in the second row, and a certain number of students in the third row. if there are a total of 62 students, how many students are in the third row?

Answers

22+19+x = 62
combine like terms

41+x = 62
subtract 41 from both sides

x= 21
there are 21 students in the third row

To determine how many students are in the third row, subtract the sum of the students in the first two rows (22 + 19 = 41) from the total number of students (62). The result is that there are 21 students in the third row.

The student is asking a question related to basic arithmetic, specifically subtraction and problem-solving skills. To find out how many students are in the third row, we subtract the number of students in the first two rows from the total number of students. There are 22 students in the first row and 19 in the second row. The total number of students is 62.

So, we calculate the number in the third row as follows:

Calculate the combined number of students in the first two rows: 22 (first row) + 19 (second row) = 41 students.Subtract the number of students in the first two rows from the total number of students: 62 (total) - 41 (combined first and second rows) = 21 students.

Therefore, there are 21 students in the third row.

Janelle is five years younger than Louisa. In three years, Janelle will be half Louisa’s age. If j represents Janelle’s age now and l represents Louisa’s age now, which matrices represent the situation?

Answers

Answer: C

Step-by-step explanation: Got it right

Final answer:

The matrix form representing the given situation with Janelle and Louisa's ages is a system of linear equations derived from the word problem, and can be represented as: [1 -1 | -5] and [0.5 -0.5 | -1.5].

Explanation:

The question involves setting up equations based on the given word problem and representing them in matrix form. The situation describes a relationship between the ages of Janelle and Louisa, with Janelle being five years younger than Louisa. In three years, Janelle will be half of Louisa's age. This can be represented with two equations:

j = l - 5

j + 3 = 0.5 * (l + 3)

These equations can then be represented in matrix form. Matrices are used in mathematics to represent systems of linear equations, and the equations stages can be translated into a matrix where each row represents an equation:

Matrix for the system of equations:

[1 -1 | -5]

[0.5 -0.5 | -1.5]
The first row of the matrix represents the first equation, showing the coefficients of j and l, and the constant term on the right side of the equation. The second row represents the second equation with the respective coefficients and constant term.

I'm not sure what the measure of R is, but I think the measure of F is 55°. I'm not 100% sure, which I feel terrible about, but I am positive that C= 43
:)

Answer: The measure of ∠F=55°

The measure of ∠R=36°

The measure of ∠C=43°

Step-by-step explanation:

The angle sum property of triangle say that the sum of all the interior angles of a triangle is 180 degrees.

Therefore By using angle sum property in Δ RST

∠R+∠S+∠T=180°

⇒∠R+76°+68°=180°

⇒∠R=180°-144°

⇒∠R=36°

In Δ CDE, where ∠C is a right angle.

∠C+∠D+∠E=180°

⇒∠C+90°+47°=180°

⇒∠C=180°-137°

⇒∠C=43°

In ΔDEF

∠D+∠E+∠F=180°

⇒104°+21°+∠F=180°

⇒∠F=180°-125°

⇒∠F=55°
