3x+3y+2(2x-y) equivalent fractions to this problem

Mathematics
1 answer:
Anastaziya [24]3 years ago
6 0
Distribute the 2 into the 2x and -y

Then add “like terms” which are 3x and 4x... 3y and -2y

Which then becomes 7x+y

There are no more “like terms” so that is your final answer

If p=(-3,-2) and q=(1,6) are the endpoints of the diameter of a circle find the equation of the circle
stira [4]

Answer:

<em>The equation of the circle   (x +1) )² +(y-(2))² = (2(√5))²</em>

<em>   or </em>

<em>The equation of the circle    x² + 2 x + y² - 4 y  = 15</em>

<u>Step-by-step explanation:</u>

Given points end  Points are p(-3,-2) and q( 1,6)

<em>The distance of two points formula</em>

P Q = \sqrt{x_{2} - x_{1})^{2} + ((y_{2} -y_{1})^{2}   }

P Q = \sqrt{1 - (-3)^{2} + ((6 -(-2))^{2}   }

P Q = \sqrt{16+64} = \sqrt{80}

<em>The diameter 'd' = 2 r</em>

                       2 r = √80

                            = \sqrt{16 X 5}

                           = 4 \sqrt{5}

                     <em> r =  2√5</em>

<em>Mid-point of two end points </em>

<em>                        </em>(\frac{x_{1} + x_{2} }{2} , \frac{y_{1} +y_{2} }{2} ) = (\frac{-3+1}{2} ,\frac{-2 +6}{2} )<em></em>

<em>                                               = (-1 ,2)</em>

<em>Mid-point of two end points = center of the circle</em>

<em>                                     (h,k) = (-1 , 2)</em>

                 

The equation of the circle

           (x -h )² +(y-k)² = r²

<em>          (x -(-1) )² +(y-(2))² = (2(√5))²</em>

<em>         x² + 2 x + 1 + y² - 4 y + 4 = 20</em>

<em>          x² + 2 x + y² - 4 y  = 20 -5</em>

<em>           x² + 2 x + y² - 4 y  = 15</em>

<u><em>Final answer</em></u><em>:-</em>

<em>The equation of the circle   (x +1) )² +(y-(2))² = (2(√5))²</em>

<em>   or </em>

<em>The equation of the circle    x² + 2 x + y² - 4 y  = 15</em>

<em>                  </em>

An ice cream cone is filled with a vanilla and chocolate ice cream at a ratio of 2:
nirvana33 [79]
\bf \textit{volume of a cone}\\\\&#10;V=\cfrac{\pi r^2 h}{3}\quad &#10;\begin{cases}&#10;r=radius\\&#10;h=height\\&#10;----------\\&#10;diameter=2\\&#10;r=\frac{diameter}{2}\\&#10;\quad = 1\\&#10;h=6&#10;\end{cases}\implies V=\cfrac{\pi\cdot  1^2\cdot 6}{3}&#10;\\\\\\&#10;V=2\pi \\\\&#10;-------------------------------

\bf \cfrac{\stackrel{vanilla}{volume}}{\stackrel{chocolate}{volume}}\qquad 2:1\qquad \cfrac{2}{1}\implies \cfrac{2\cdot \frac{V}{2+1}}{1\cdot \frac{V}{2+1}}\implies \cfrac{2\cdot \frac{2\pi }{2+1}}{1\cdot \frac{2\pi }{2+1}}&#10;\\\\\\&#10;\cfrac{2\cdot \frac{2\pi }{3}}{1\cdot \frac{2\pi }{3}}\implies \cfrac{\quad \frac{4\pi }{3}\quad }{\frac{2\pi }{3}}

What is 1 3/7 as an improper and equivalent fraction?
Alex777 [14]
Improper: multiple the 1 by the denominator 1x7 = 7 then add to numerator number.

Final answer is 10/7

And equivalent fraction could be anything as long as it’s equal to the original.

Possible could be 1 9/21

What is the equation of the line in slope–intercept form that passes through the point (0, 3) and is perpendicular to the line y
Liula [17]
Y = 2x - 6 => slope is 2
For perpendicular lines, m2 = -1/m1
Slope of the required line is -1/2
Required equation is (y - 3)/(x - 0) = -1/2 => y - 3 = -1/2 x => y = -1/2 x + 3

The Sum of two numbers is 25. One of the numbers exceeds the other by 9. Find the numbers.
Step2247 [10]

Answer:

8 and 17

Step-by-step explanation:

Let the number x and y

Sum of numbers, x + y = 25 -----------( 1 )

One number exceeds other by 9,

 that is difference between the numbers is 9, x - y = 9

                                                                       => x = 9 + y   --------- ( 2 )

Substitute ( 2 ) in ( 1 )

( 9 + y ) + y = 25

2y = 25 - 9

2y = 16

y = 8

Substitute y = 8 in ( 2 ) : x = 9 + y

                                        = 9 + 8 = 17

Therefore the 2 numbers are 8 and 17
