If 3x+5y=13 and 6x+7y=20 what is the value of y/x?

Answers

Answer 1
3x + 5y = 13 ....multiply by -2
6x + 7y = 20
----------------
-6x - 10y = -26 (result of multiplying by -2)
6x + 7y = 20
---------------add
-3y = -6
y = -6/-3
y = 2

3x + 5y = 13
3x + 5(2) = 13
3x + 10 = 13
3x = 13 - 10
3x = 3
x = 3/3
x = 1

so if x = 1 and y = 2.....then y/x = 2/1 = 2 <==
Answer 2

The value of the variables 'x' and 'y' will be 1 and 2, respectively. Then the value of the expression y / x will be 2.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The system of equations is given below.

3x + 5y = 13          ...1

6x + 7y = 20        ...2

Multiply the equation 1 by -2, then we have

6x + 7y = 20            ...2

- 6x - 10y = - 26          ...3

Add both equations, then we have

- 3y = - 6

y = 2

Then the value of the variable 'x' will be given as,

3x + 5(2) = 13

3x = 3

x = 1

The value of the expression y / x will be given as,

y / x = 2 / 1

y / x = 2

The value of the variables 'x' and 'y' will be 1 and 2, respectively. Then the value of the expression y / x will be 2.

Given 7x + 11y = N, what is the highest number N can be to produce an answer of No solution. (X,y) must be positive.

Answers

Since x and y must be positive, 7x and 11y are positive either. That means 7x + 11y > 0. Then we would obtain N > 0 because 7x + 11y = N. That also means N must be positive. So if we set N to be zero or negative, there would be no solution. Thus, to produce an answer of No solution, the highest number N could be is 0.

a regular polygon must have ___ sides if each interior angle measure is four times the measure of each exterior angle

Answers

Int Angle + Ext Angle = 180
4Ext + Ext = 180
Ext = 36 degrees
-----
360/36 = 10 sides

The sum of the interior angles of the polygon is 1440° and the number of sides of the polygon is 10 sides

What is the sum of the interior angles of a polygon?

The sum of the interior angles of a polygon is given by the formula

Sum of Interior angles of a polygon with n sides is

nθ = 180 ( n - 2 )

where n is the number of sides

θ = angle in degrees

Given data ,

Let the sum of the interior angles of the polygon be S

Now , the number of sides = n

The sum of the exterior angles of a polygon = 360°

And , each interior angle measure is four times the measure of each exterior angle

Substituting the values in the equation , we get

180 ( n - 2 ) = 4 ( 360 )

On simplifying the equation , we get

180n - 360 = 1440

Adding 360 on both sides of the equation , we get

180n = 1800

Divide by 180 on both sides of the equation , we get

n = 10 sides

Hence , the number of sides of the polygon is 10 and it is a decagon

The horizontal beams are what I like to think of as "rail road tracks". The metal portion of the tracks anyway. Notice how angle 2 and angle 8 are inside the tracks, so we consider them "interior angles"

Furthermore, they are on opposite or alternate sides of the transversal line. The transversal line is the non-parallel line that cuts through the "rail road tracks".

Two airplanes leave chicago's midway airport at the same time, traveling in opposite directions. one travels at 25 miles per hour faster than the other. after 2 hours they are 490 miles apart. find the speed of each airplane.

Answers

Final answer:

The first airplane travels at 110 miles per hour, and the second airplane travels at 135 miles per hour.

Explanation:

The question deals with two airplanes leaving Chicago's Midway Airport at the same time and heading in opposite directions.

One travels at a speed that is 25 miles per hour faster than the other.

After 2 hours, they are 490 miles apart, and we need to find the speed of each airplane.

Let's define the speed of the slower airplane as x miles per hour.

Then, the faster airplane's speed would be x + 25 miles per hour.

Since they are traveling in opposite directions for 2 hours, we can set up the equation:

2x + 2(x + 25) = 490

Solving for x will give us the speed of the slower airplane, and x + 25 will give us the speed of the faster airplane.

2x + 2x + 50 = 490
4x + 50 = 490
4x = 440
x = 110

Thus, the speed of the slower airplane is 110 mph, and the faster airplane is 135 mph (110 mph + 25 mph).

Write an equation for a rational function with: vertical asymptotes at x = -4 and x = 4 x-intercepts at x = -6 and x = 5 horizontal asymptote at y = 8

Answers

Final answer:

A rational function with the required characteristics is f(x) = 8(x + 6)(x - 5) / (x + 4)(x - 4), considering vertical asymptotes, x-intercepts, and a horizontal asymptote.

Explanation:

To write an equation for a rational function with given characteristics, we need to incorporate the vertical asymptotes, x-intercepts, and horizontal asymptote into our function.

Firstly, vertical asymptotes at x = -4 and x = 4 suggest that the denominator of our function will be in the form (x + 4)(x - 4), as setting x to -4 or 4 will make the denominator zero, which creates the asymptotes.

Secondly, x-intercepts at x = -6 and x = 5 indicate that the numerator will have factors that become zero at these x-values. Hence, the numerator should be(x + 6)(x - 5).

Finally, for the function to have a horizontal asymptote at y = 8, the degree of the numerator and denominator must be the same, and the leading coefficients of the numerator and denominator must have a ratio that equals 8. To achieve the horizontal asymptote, we multiply the numerator by 8, thus the leading coefficients of the numerator and denominator are in the ratio 8:1.

Combining all these elements gives us our rational function: f(x) = 8(x + 6)(x - 5) / (x + 4)(x - 4)

As Mercury revolves around the sun, it travels at a rate of approximately 30 miles per second. Convert this rate to miles per minute. At this rate, how many miles will Mercury travel in 4 minutes?

Answers

30 miles per second times 60 seconds = 1,800 miles per minute.
To find out for 4 minutes, now we multiply 1,800 miles times 4 which = 7,200 miles.
In 4 minutes, Mercury will travel 7,200 miles.

The number of miles that Mercury travels in 4 minutes will be 7,200 miles.

What is the rate?

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

Unit modification is the process of converting the measurement of a given amount between various units, often by multiplicative constants that alter the value of the calculated quantity without altering its impacts.

As Mercury revolves around the sun, it travels at a rate of approximately 30 miles per second.

Convert the rate into miles per minute. Then we have

Rate = 30 x 60

Rate = 1,800 miles per minute

At this rate, the number of miles that Mercury travels in 4 minutes will be given as,

D = 1,800 x 4

D = 7,200 miles

The number of miles that Mercury travels in 4 minutes will be 7,200 miles.

Given △ABC≅△JKL , m∠B=55° , and m∠L=25° , what is the measure of ∠J ? Enter your answer in the box.

Answers

<J = 100 is your answer!

Answer:

m∠J = 100° is the answer.

Step-by-step explanation:

Given : ΔABC ≅ ΔJKL,

            m∠B = 55°

            m∠L = 25°

To find : ∠J

Since in both the triangles ABC and JKL

m∠A ≅ m∠J

m∠B ≅ m∠K = 55°

m∠C ≅ m∠L = 25°

Since measure of ∠K and ∠L are known then we can calculate the third angle j

m∠J + m∠K + m∠L = 180°

55° + 25° + m∠J = 180°

80° + m∠J = 180°

m∠J = 180 - 80

        = 100°

Therefore, m∠J = 100° is the answer.

Is y=4x-1 and 12x=3y+7 parallel, perpendicular, or neither

Answers

first, you simplify 12x=3y+7. Subrtact 7 from both side, get 12x-7=3y. Divide 3 from both sides, get y=4x-(7/3). Your 2 equations are y=4x-1 and y=4x-7/3. The 2 lines are parallel, since they have the same slope but different b's.

Answer:

Neither is the answer.

Step-by-step explanation:

If a line y = m₁x + c₁ and y = m₂x + c₂ are perpendicular to each other then m₁ × m₂ = -1

If both the lines are parallel to each other then m₁ = m₂

Now two lines have been given as

y = 4x - 1 ----------(1)

12x = 3y + 7

3y = -12x + 7

y = -4x + [tex]\frac{7}{3}[/tex]------(2)

Now from equation (1) and equation (2),

m₁ = 4 and m₂ = -4

Since m₁ ≠ m₂

Therefore, these lines are not parallel

m₁ × m₂ = 4 × (-4) = -16

Therefore, both the lines are neither parallel nor perpendicular.
