Which of the following graphs represents the equation x-5y=27

Answers

Answer 1

The graph that shows the straight line → x - 5y = 27 is plotted and attached.

What is the general equation of a straight line?

The general equation of a straight line is -

y = mx + c

where -

[m] is slope of the line.

[c] is the y - intercept of the line.

Given is the equation of the line as -

x - 5y = 27

The given equation of the line is -

x - 5y = 27

Rearranging the equation, we get -

5y = x - 27

y = (1/5)x - (27/5)

y = 0.2x - 5.4

Now, refer to the graph attached. The slope [m] of the equation will be -

m = 0.2 and the [y] - intercept will be y = - 5.4.

Therefore, the graph that shows the linear relation → y = 0.2x - 5.4 is plotted and attached.

y = 13x + 18
1. Find the slope of the two points. 6-(-7) is 13 and -1 -(-2) is 1, so the slope is 13/1.

2. Write the equation in point slope form.
y - y1 = m(x - x1)
y - 6 = 13(x -(-1)

3. Use distributive property.
y - 6 = 13x + 13

The admission fee at the museum is 8.50 for children and 12.50 for adults on a certain day, a total of 240 people entered the museum and 2400$ was collected.

Use the variable c to represent children and the variable a to represent the adult

Answers

Answer:

Below

Step-by-step explanation:

a + c = 240 re-arrange to c = 240-a

revenue from child tix = 8.50 ( 240-a)

revenue from adult tix = 12.50 a summed, the revenues = 2400

8.5(240-a) + 12.5 a = 2400

2040 - 8.5 a + 12.5 a = 2400

4.5 a = 360

a = 80 tix then c = 240 - a = 160 tix

write an expression that is equivalent to 2/3 (4x + 9)

Answers

Hello,

I hope you and your family are doing well!

To write an expression that is equivalent to 2/3 (4x + 9), you can simply distribute the 2/3 over the parentheses:

2/3 (4x + 9) = (2/3 * 4x) + (2/3 * 9)

This simplifies to:

2/3 (4x + 9) = (8/3)x + (18/3)

Therefore, an expression that is equivalent to 2/3 (4x + 9) is (8/3)x + (18/3).

Please rate this answer 5 stars and brainliest if you find it helpful.

Happy Holidays & New Year!

Answer: 2 2/3x + 6

Step-by-step explanation: 1 of 3 ways to find how to make the equivalent is to use the distributive property. So, that means we need to multiply or distribute 2/3 to both 4x and 9. So, 2/3 x 4 is roughly 2 2/3. Also, 2/3 x 9 = 6. So, I combined the like terms to get 2 2/3x + 6 as my equivalent expression. I hope this helps.

The probability of choosing red ribbon on both Monday and Tuesday is 1/4.

What is the probability?

The Probability in mathematics is possibility of an event in time. In simple words how many times that incident is happening in any given time interval.

Given that each morning Tess chooses either red ribbon or blue ribbon at random to wear in her hair.

That means probability of choosing between blue or red is 1/2 in one morning.

Now the probability of choosing red ribbon on both Monday and Tuesday,

1/2 × 1/2

What is triangle ?

A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.

A triangle is a 3-sided polygon that is occasionally (though not frequently) referred to as the trigon. There are three sides and three angles in every triangle, some of which may be the same.

AC and BD bisects one another

AE = CE --- Side

and

BE = DE --- Side

When both lines bisect one another, they form a pair of vertical angles and

When we apply the theorem of vertical angles to this, we have that:

∠AEB = ∠CED --- Angle

At this point, we have established:

Two sides of ABE and CDE are congruent and One angle in each of ABE and CDE are also congruent

Hence, the triangles are congruent by SAS.

Answer:

A = 25t + 300

B = 55t + 150

Less than 5 hours, company B would be cheaper. At 5 hours the cost is equal. After 5 hours, company A would be cheaper.

Step-by-step explanation:

Company B would be cheaper for lower hours.

The the two equation equal to each other and solve for to find out when the costs will be equal.

25t + 300 = 55t + 150 Subtract 25t from both sides

300 = 30t + 150 Subtract 150 from both sides

150 = 30t Divide both sides by 30

5 = t

At 5 hours the cost are the same, after 5 hours company A would be cheaper.

6x + 3y = 3 3x - y = 4

Answers

Answer:

x = 1

y = -1

Step-by-step explanation:

Given equations:

6x + 3y = 3 -------------(1)

3x - y = 4 ----------------(2)

Multiply Eq. (2) by 2

2(3x - y) = 4 × 2

6x - 2y = 8 -------------(3)

Subtract Eq. (3) from Eq. (1)

6x + 3y - (6x - 2y) = 3 - 8

6x + 3y - 6x + 2y = -5

3y + 2y = -5

5y = -5

Divide 5 to both sides

y = -5/5

y = -1

Put y = -1 in Eq. (1)

6x + 3(-1) = 3

6x - 3 = 3

Add 3 to both sides

6x = 3 + 3

6x = 6

Divide 6 to both sides

a) Work out the minimum number of dogs that could have a mass of more than 24kg}
b) Work out the maximum number of dogs that could have a mass of more than 24kg

Answers

The minimum number of dogs 24kg is 6 and the maximum number of dogs is 18

Maximum and Minimum:

The highest amount or value or number that may be obtained or reached or can be counted is the Maximum value

The least amount or value or number that may be admitted or reached or can be counted is the Minimum value

Here we have a table

Which represents the masses of various dogs

Mass (x) kg frequency

0 ≤ x < 10 2

10 ≤ x < 20 7

20 ≤ x < 30 12

30 ≤ x < 40 6

Here the mass of dogs is represented in class intervals

a) The minimum number of dogs with a mass of more than 24kg.

From the given table,

24 kg will lie in class intervals 20 ≤ x < 30, and 30 ≤ x < 40

In class interval 20 ≤ x < 30, there is a possibility that the mass of dag will be less than 24 kg since it started from 20 kg and is up to 30 kg

In class interval 30 ≤ x < 40, there is no possibility that the mass will be less than 24 kg since it started from 30 kg and is up to 40 kg

So The minimum number of dogs that have a mass of more than 24kg the frequency of class interval 30 ≤ x < 40

Therefore,

The minimum number of dogs with a mass of more than 24kg is 6

b) The maximum number of dogs that have a mass of more than 24kg.

To get the maximum number of dogs we need to take the class interval of 20 ≤ x < 30 as in this the mass could be more than 24 kg.

And in class 30 ≤ x < 40 the mass will be more than 24 kg.

Thus, the Maximum number of dogs with more than 24 kg = 12 + 6 = 18

Therefore,

The maximum number of dogs with a mass of than 24kg is 18

How to calculate the value of x(angle)?

A straight line's total number of angles adds up to 180°. Supplementary angles are two angles whose sums equal 180 degrees. Angles are referred to as neighbouring if they have a similar vertex and side.A straight angle in mathematics is one with a degree value of 180. Because it resembles a straight line, it is called straight.Angles in a straight line are the total of all the angles that can be arranged in a straight line. Straight line angles add up to 180°.

The angle of the straight line = 180°

156° + x = 180°

The ordered pair of the inequality 6x + 5y < -15 are (2, 0) and (3, 2).

What is inequality?

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.

Considering the provided inequality and the provided ordered pairs, we will check it by replacing one by one in the inequality; if the inequality is fulfilled, they are the solution; otherwise, they are not, so we obtain:

(2, 0):

6x + 5y > 2

6(2)+5(0)>2

12+0>2

12>0

Since the inequality holds, then the ordered pair is a solution.

(7, -8):

6x + 5y > 2

6(7)+5(-8) > 2

42-40>2

2>2

Since the inequality is not satisfied, then the ordered pair is not a solution.

(3, 2):

6x + 5y > 2
