Mathematics

Answer:

|answer|  \\ 1)0=0 \\ 2)0=28

3)The example equation becomes "x + 10 - 15x = 20," which is then "-14 x + 10 = 20." Subtract 10 from each side, divide by 14 and you have end up with x = -10/14, which simplifies to x = -5/7. Plug in the x value in to the first equation to find out the y value. y = 2 - 3(-5/7) becomes 2 + 15/7, which is 29/7.

If you type the equation into y1 on your calculator and use the table graph you get coordinates that you can graph. ( 0,-9 ) ( 1,-6 ) ( 2, -3 ) ( 3 , 0 ) ( 4, 3 ) ( 5 , 6 ) ( 6 , 9 ), just graph those and that should answer your question :)

Write f(x)= a(x-h)2+k and identify the vertex
Nesterboy [21]
Hello : 
2x²+4x-5 = <span>a(x-h)2+k =a(x²-2xh+h²)+k
</span>2x²+4x-5 = ax²-2ahx +ah² +k
a=2.....(1)
-2ah = 4.....(2)
ah²+k=-5...(3)
in (2) : -4h=4      h=-1
in(3) : 2(-1)²+k=-5    k = -7
conclusion : 2x²+4x-5 = 2(x+1)²-7
<span>the vertex is : A(-1,-7)</span>
