Answer:
it is X-.3333 or X -1/3
Step-by-step explanation:
Answer:
26
Step-by-step explanation:
if you can get 8 oranges for 10.40 then divide 10.40 by 8. you can get each orange for 1.3. you need to know how many oranges you can get for 33.8 so divide that by 1.3 and you get 26
If the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.
Then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.
One way in which you can find the vertex is to calculate x = -b / (2a). Here, that comes to
-(-2)
x = ---------- = 1. f(1) = 1^2 - 2(1) - 8 = - 9. Vertex is at (1, -9).
2(1)
Find another point on the curve: Let x=0, for which y=-8. Then (0, -8) is on the curve. Plot the vertex and this point and draw a smooth parabola thru both.
divide 9 by 10. (the numerator and denominator) = 9 / 10 = 0.9
add the 0.9 to the 3 so, 3 + 0.9 = 3.9
answer: 3.9
The answer is four... i had to write it out instead of plainly stating 4. hope you get it correct. goodluck . la la al ala la al mla
