it's actually none of these.

Step-by-step explanation:

if we divide 15 by 3 we also have to divide 42 by 3. We end up with 5:14. 15 isn't divisible by any number other than 1, 3, 5, and 15.

Answer:

[tex]V_2= \frac{28}{3} u^3[/tex]

Step-by-step explanation:

Given

Represent the volume of the cylinder with V1 and the volume of the sphere with V2

So, from the first statement: we have:

[tex]V_2 =\frac{2}{3}V_1[/tex]

and

[tex]V_1 = 14u^3[/tex]

To solve for [tex]V_2[/tex], we simply substitute [tex]14u^3[/tex] for [tex]V_1[/tex] in [tex]V_2 =\frac{2}{3}V_1[/tex]

[tex]V_2 =\frac{2}{3}V_1[/tex]

[tex]V_2= \frac{2}{3} * 14u^3[/tex]

[tex]V_2= \frac{2* 14}{3} u^3[/tex]

[tex]V_2= \frac{28}{3} u^3[/tex]

Hence, the volume of the sphere is [tex]\frac{28}{3} u^3[/tex]

Answer:

x,y =3,-4

Step-by-step explanation:

// Solve equation [1] for the variable  y

 [1]    y = 2x - 10

// Plug this in for variable  y  in equation [2]

  [2]    3x - 2•(2x-10) = 17

  [2]    -x = -3

// Solve equation [2] for the variable  x

  [2]    x = 3

// By now we know this much :

   x = 3

   y = 2x-10

// Use the  x  value to solve for  y

   y = 2(3)-10 = -4

Answer:

y= -2.5x-4

Step-by-step explanation:

we have to isolate our y

subtract 5x from 5x+2y=-8 and move it to the right side

2y= -5x-8

divide everything by 2

y=-2.5x-4

I hope this helped you :)

Answer:

Step-by-step explanation:

(-3 -5)/(9+5)= -8/14= -4/7

y - 5 = -4/7(x + 5)

y - 35/7 = -4/7x - 20/7

y = -4/7x + 15/7

Answer:

y = 3/5x - 17/5

Step-by-step explanation:

slope formula: (y₂ - y₁) / (x₂ - x₁)

First, plug in these values of the two given points.

(-4 - (-1)) / (-1 - 4)

Simplify within the parentheses.

(-4 + 1) / (-1 - 4)

(-3) / (-5)

3/5

This is your slope. Plug this into a standard slope-intercept equation: y = mx + b

To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (-1, -4). Plug in the x and y values into the x and y of the standard equation.

-4 = 3/5(-1) + b

Multiply.

-4 = -3/5 + b

Add 3/5 to both sides. -- To add it easier, convert 4 to a have a denominator of 5.

-20/5 = -3/5 + b

-20/5 + 3/5 = b

-17/5 = b

Now, plug this into your standard equation.

y = 3/5x - 17/5

Check this equation by plugging in the other point you did not use (4, -1)

-1 = 3/5(4) - 17/5

-1 = 12/5 - 17/5

-1 = -5/5

-1 = -1

Your answer is correct!

Hope this helps!

The quadrilateral that is illustrated based on the information and diagram is a square.

A quadrilateral is a plane figure with four edges and four corners, also known as vertices. The quadrilateral's four vertices or corners all have angles. A quadrilateral has four straight sides and is a two-dimensional shape. Parallelograms, trapezoids, rectangles, kites, squares, and rhombuses are a few examples of quadrilaterals.

A quadrilateral with four equal sides and angles is called a square. Due to its equal sides and angles, it is also a regular quadrilateral. A square has four 90° angles, just like a rectangle does. It can also be thought of as a rectangle with equal lengths on its two adjacent sides. A square is a quadrilateral with four equal sides and four equal angles that is a regular quadrilateral. The square's angles are at a right angle or 90 degrees.

Step-by-step explanation:

They are all the same its just different form

==================================

Work Shown:

m = -5 is the slope

(x1,y1) = (-3,-7) is the point the line goes through

Plug this into the point slope form below and simplify.

y - y1 = m(x - x1)

y - (-7) = -5(x - (-3))

y + 7 = -5(x + 3)

Side note: If we solved for y, we'd get y = -5x - 22 showing that -22 is the y intercept.

Answer:

If A Point, Ray, Line Segment, or Plane intersects a segment at its midpoint, then it Bisects the segment.

Step-by-step explanation:A segment, ray, line, or plane that is perpendicular to a segment at its midpoint is called a perpendicular bisector. If a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment. Point is equidistant from two points if its distance from each point is the same.
