Answer:
100
Step-by-step explanation:
This is true. An arithmetic sequence is one that either goes up or goes down by the same number every time. This equation that they gave you is linear, therefore, it will always go up or down by the same amount every time. Not so with other types of functions, but always with linear.
2,273 - 1,920.47 is = to 352.53
and the other problem is
2,281 - 1,945.07 is = to 335.93
I think rational, what's the situation
H (x) = 5x^2+40x+64
y = (5x^2+40x+60) + 4
y = 5(x^2+8x+12) + 4
y = 5(x+2)(x+6) + 4
y-4 = 5(x+2)(x+6)
This means that the solutions, or where the parabola crosses the x-axis, are at x+2=0 and x+6=0, or x=-2, -6
So the midpoint of -2 and -6 is -4, the axis of symmetry is x=-4
