The graph of a quadratic equation is a U-shaped curved called parabola. It is because the parabola makes very easy to find the axis of symmetry to plot selected points and finding the roots and vertex.
Good luck :)
Answer:
9/10
Step-by-step explanation:
There are 20 and 2 green 20-2 is 18 so 18/20 simplified is also 9/10
Answer:
\frac{276}{5}-8x)
Step-by-step explanation:
We are given with
H(x)=1/3x3/3 3x2+9x-2
And
M(x)=13 3/5x+6x3-2x2-4x
And asked to determine
[h(x) +m(x)]-[h(x)-m(x)]
Opening the second parenthesis
h(x) +m(x)-h(x)+m(x)
As we subtracted the second bracket, the sign get reversed.
As h(x) has opposite signs , they get cancelled
h(x) +m(x)-h(x)+m(x)
=2m(x)
=2(13\tfrac{3}/{5}x+6x3-2x2-4x)
=2(\frac{13 \times 5 + 3}{5}+18-4-4x)
=2(\frac{68}{5}+14-4x)
=2(\frac{68+70}{5}-4x)
=2(\frac{138}{5}-4x)
=\frac{276}{5}-8x)
Answer:
(9, -3)
Step-by-step explanation:
The coordinates of the midpoint are the averages of the coordinates of the endpoints.
For the x coordinates:
3 = (-3 + x) / 2
x = 9
For the y coordinates:
3 = (9 + y) / 2
y = -3
The other endpoint is at (9, -3)
