What are the solutions to y=10x2+29x−21

Jlenok [28]

Answer:

x 2 +(29/10)x-(21/10) = 0 Add 21/10 to both side of the equation : x 2 +(29/10)x = 21/10 Now the clever bit: Take the coefficient of x , which is 29/10 , divide by two, giving 29/20 , and finally square it giving 841/400 Add 841/400 to both sides of the equation

5y=2x<br> Can someone explain the steps to solving this

Elena-2011 [213]

Answer:

You can't solve this with only this much info.

Step-by-step explanation:

There are 2 varibles y and x. You have to at least have 2 different equations with only variables y and x or know the value of one. Of course you could guess but then there would be multiple answers. like y=1, x=2.5, etc.

B(4, 0) and c(10, 4) are the endpoints of a line segment. what is the midpoint m of that line segment? answer

Lilit [14]

The midpoint formula is $Midpoint: ( x_{m} , y_{m} )=( \frac{sum of x coordinates}{2} , \frac{sum of y coordinates}{2} )$

Therefore,
$x_{m}= \frac{4+10}{2} =7$
$y_{m}= \frac{0+4}{2} =2$

Answer: (7,2)
You could also plot the points and fold the paper so the points are on top of each other. Make a crease in the paper and when you open it the point where the crease intersects the segment is the midpoint.
