wut is this answer . i have no clue what this is

Answer:

\(\sf y=\dfrac{1}{3}x\)

Step-by-step explanation:

First find the slope:

\(\sf slope\:(m)=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{4-5}{12-15}=\dfrac{1}{3}\)

Use the point-slope form of linear equation:  \(\sf y-y_1=m(x-x_1)\)
(where m is the slope and (x₁, y₁) is a point on the line)

with the found slope and one of the points:

\(\begin{aligned}\sf y-y_1 &=\sf m(x-x_1)\\\\\implies \sf y-4 &=\sf \dfrac{1}{3}(x-12)\\\\\sf y-4 &=\sf \dfrac{1}{3}x-4\\\\\sf y &= \sf \dfrac{1}{3}x\end{aligned}\)

Step-by-step explanation: The answe is y= 3 because first of all to find the answer for this question you need to divide first x and then y like this steps that i did that are shown below.

21/7=3

15/5=3

12/4=3

so hopefully 3 is the correct answer and have a great day everyone and if you want please give me brainliest.

Vertical change is -2.1 and horizontal change is 8.4, so slope is (-2.1)/(8.4)=-1/4.

Answer:

1/2 pi

Step-by-step explanation:

This is 1/4 of a circle

Find the  circumference and multiply by 1/4

1/4 C

1/4 ( 2*pi*r)  where r is the radius

The radius is 1

1/2 pi*1

1/2 pi

Answer:

Step-by-step explanation:

A full circle has a circumference of 2*pi * r

r = 1

so Full Circle = 2 * PI

1/4 Circle = 2*pi / 4 = 1/2 pi

The length of the arc length = 1/2 pi

Just in case you prefer the more numerical answer, 1/2 * 3.14 = 1.57

Step-by-step explanation:

If possible, please provide a picture otherwise we do not know what to answer. First move 0.25+ along the x axis, then -1.75 in the y direction. it should look like this

This figure is a triangle. Using the definition of triangles, it is determined that angles 1, 2, and 3 add up to 180 degrees. In this instance, we know the values of 2 combined angles. With this information it is only necessary to subtract the values of angles 1 and 2 (134) from 180 degrees to find the value of angle 3. This leads us to the solution that angle 3 has a value of 46 degrees.

A, C, and D.

Step-by-step explanation:

(a) Christine will decompose the shape into 2 trapezoid

(b) Christine will need 29 square feet area of carpet

area of the trapezoid is calculated using the formula: 1/2 × (AB + CD) × height, where AB and CD are the lengths of its parallel sides.

(a). The shape will be decomposed into two (2) trapezoid

(b). For the bigger trapezoid;

8ft 6in = 8.5 ft

area of bigger trapezoid = 1/2 × (8.5 + 12) × 2 ft²

area of bigger trapezoid = 20.5 ft²

For the smaller trapezoid;

2ft 6in = 2.5 ft

area of smaller trapezoid = 1/2 × (2.5 + 6) × 2 ft²

area of smaller trapezoid = 8.5 ft²

Total square feet area of carpet = 20.5 ft² + 8.5 ft²

Total square feet area of carpet = 29 ft²

Therefore, (a) Christine will decompose the shape into 2 trapezoid

(b) Christine will need 29 square feet area of carpet

Step-by-step explanation:

Q6)

Kerry's workday is 10 hrs. and works 40 hrs. per week, Kerry works for 4 days

Watson's workday is 8 hrs. and works 40 hrs. per week, Watson works for 5 days

Kerry: works 4 days and gets paid $ 12.75 per cat & grooms 15 cats per day, so Kerry makes = 4(12.75 × 15) = 4(191.25) = $ 765

Watson: works 5 days and gets paid $ 12.75 per cat & grooms 10 cats per day, so Watson makes = 5(12.75 × 10) = 5(127.50) = $ 637.50

∴ The difference between their weekly earning is 765 - 637.50 = $ 127.50

Answer: hope this helps ♡

A:  \(-\frac{3}{8}\) b + \(\frac{15}{24}\)

B:  \(-\frac{1}{8}\)  (3b - 5)

Step-by-step explanation:

Part A

\(-\frac{1}{4}\) b + \(\frac{1}{12}\) -  \(\frac{1}{8}\) b + \(\frac{13}{24}\)

=  \(-\frac{1}{4}\) b -  \(\frac{1}{8}\) b + \(\frac{1}{12}\) + \(\frac{13}{24}\)

=  \(-\frac{2}{8}\) b -  \(\frac{1}{8}\) b + \(\frac{1}{12}\) + \(\frac{13}{24}\)

=  \(-\frac{3}{8}\) b + \(\frac{1}{12}\) + \(\frac{13}{24}\)

=  \(-\frac{3}{8}\) b + \(\frac{2}{24}\) + \(\frac{13}{24}\)

=  \(-\frac{3}{8}\) b + \(\frac{15}{24}\)

Part B

• \(-\frac{1}{8}\)  (3b - 5)

Answer:

5x + 15y =20  = - 3x +25y =75

= 8 minutes

Step-by-step explanation:

5x + 15y =20    multiply all by 3 to get 15x

15x +45y=60

- 3x +25y =75 multiply all by -5 to get 15x

15x -125y = -375

rewrite ans together

15x +45y=60

15x -125y = -375

      -80y = -315

y = -315/ - 80

y = 3.9375  = y= 4 substitute to find x

5x + 15(4 )=20  

5x +60 = 20

5x=-40

x= -40/5

x=-8

15x +45(4)=60

15x +180 =60

15x =-120

x=-8

Answer:

The art teacher is incorrect.

Step-by-step explanation:

Coming Up with Compatible Estimate Numbers:

The teacher has 47 1/3 pounds of clay. We can round this to 50. Now we have 50 pounds of clay.

Explaining the Operations:

The teacher wanted to distribute the clay by 2.5 lbs. This means we need to divide the amount of clay by 2.5.

Performing the Operations:

Divide 50 by 2.5 ---> 50÷2.5=(5÷2.5)*10--->5÷2.5=2--->2*10=20

Final Conclusion

For every student, the art teacher plans to give 2.5 lbs of clay. This means he will divide his 47 1/3 pounds by 2.5 piles and hand them out to the students. If we round 47 1/3 to 50 (about 2 points higher) and divide 50 by 2.5, you get 20. This means he would have a little less than enough clay for 20 students, not 9. Therefore, the art teacher is incorrect.

****ANOTHER POSSIBLE SOLUTION****

You can also multiply 9 x 2.5 and see if the product is close to 47 1/3. In this case, you can round 2.5 to 3 and proceed with the multiplication. 9*3=27 Since 27 is a lot lower than 47 1/3, the art teacher is incorrect.

Answer:

its A brainly plz

Step-by-step explanation:

Answer:

In the given equations, "m" represents the slope of the line and "b" represents the y-intercept.

Part A includes four different equations, and they all have different values for "m" and "b". However, since there is no information about any changes in the equations or the values of "m" and "b", it is not clear which equation is being referred to in Part B.

Therefore, without additional context, it is impossible to determine whether "m" or "b" will change in the equation.
