Find the vertex of the parabola y=2x^2-16x+34

Mathematics
1 answer:

3 0

Answer:

The standard equation is y=ax^2+bx+k and the vertex way is y=a(x-h)(x-h)+x

so the coordinate for x is -b/2a, for your problem a=-4   b=-16 so the coordinate for x is -(-16)/(2*(-4))=-2. Now you have to replace x=-2 in your equation y=-4(-2)^2-16(-2)-11= 5.

The vertex is (-2, 5)

Factor each expression 16x+40y
prohojiy [21]
Hi there!

To factor this expression, you must first find the greatest common factor of each term, 16x and 40y.

To do this, first list the factors of each coefficient since they do not share any variables:
16:1,2,4,8,16
40:1,2,4,5,8,10,20,40

Notice that among the factors of each term, 8 is the greatest common factor.

Finally, factor 8 from the expression to get 8(2x+5y) as your final answer.

Hope this helps, and have a nice day!

MAVERICK [17]
The five essential hypothesizes of Geometry, additionally alluded to as Euclid's proposes are the accompanying: 
1.) A straight line section can be drawn joining any two focuses. 
2.) Any straight line portion can be expanded uncertainly in a straight line. 
3.) Given any straight line fragment, a circle can be drawn having the portion as a span and one endpoint as the inside. 
4.) All correct points are harmonious. 
5.) If two lines are drawn which meet a third such that the total of the internal points on one side is under two right edges (or 180 degrees), then the two lines unavoidably should converge each other on that side if reached out sufficiently far.
