Answer:

=2xy²+2x²y

Step-by-step explanation:

Delete the parenthesis of both operations.

= x²y - 3y² + 5xy² + x²y - 3xy² - 3y²

Then you have to make the simplification

= 2xy²+2x²y

WILL MARK BRAINIEST!!! 20 POINTS!!! Determine the equivalent system for the given system of equations. 4x − 5y = 2 10x − 21y = 1
aniked [119]

Answer:

none of the options

Step-by-step explanation:

4x − 5y = 2 , 10x − 21y = 10

---------

the first equation is same in all answer choices, let's check which is equivalent to second, the easy way is to consider x/y ratio which is 10/ -21

4x − 5y = 2 , 3x − y = 4

  • no, ratio is 3/ -1

4x − 5y = 2 , 24x − 47y = 22

  • no, the ratio is 24/ -47

4x − 5y = 2 , 10x + 3y = 15

  • no, the ratio is 10/3

4x − 5y = 2 , 14x + 26y = 12

  • no, the ratio is 14/26

What are the two ways you can find the distance between points (X1,Y1) and (x2,y2) in the coordinate
igomit [66]

The first (and most typical) way to find distance of two points is by using the distance formula.

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

One alternative is the Manhattan metric, also called the taxicab metric. This option is much more complicated, and rarely used in high school math. d(x,y)=∑i|xi-yi|

The equation of line CD is Y=3X -3. Write an equation of a line perpendicular to line CD in slope intercept form that contains p
OLga [1]
(I'm learning this right now!)

y = 3x - 3
If a line is perpendicular to another line, they have negative reciprocal slopes.
So you would use the slope -1/3.

Use y - y₁ = m(x - x₁) to get an equation in slope intercept form.
Plug the numbers in.

y - 1 = -1/3(x - 3)
y - 1 = -1/3x + 1
y = -1/3x + 2

An equation of a line perpendicular to line CD is y = -1/3x + 2.

403010Pa2 4 8 10Number of ticketsThe graph shows the cost of buying raffle tickets.19. write an equation shows the cost y in ter
Lana71 [14]
Simple..

you have y which is the cost of the tickets..and you have x which is the number of tickets..

So, you have those points on the graph....find an equation!

Take any of those coordinates..and find the equation of the line...in the form of y=mx+b

(2,10) and (5,25)

Using: \frac{ y_{1}- y_{2}  }{ x_{1}- x_{2}  }

\frac{10-25}{2-5} = \frac{-15}{-3} =5

Thus, you know your slope. m=5

But, remember it's in the form of y=mx+b

So, use any of the coordinates...let's use (2,10)

10=5(2)+b

10=10+b

0=b

Thus, your equation is... y=5x

Thus, your answer.
