Answer:
It's the first option.
Step-by-step explanation:
It is turned down so the one half is negative (-1/2)
parabola will be in the form of a(x-h)^2 + k. (-h, k) is your vertex, in this case that is (15,25). so in the equation, you will have
-1/2(x-15)^2 + 25. first one.
Hope this helps!
Answer:
2/5
Step-by-step explanation:
3/5 / 2/3
3/5 ÷ 2/3
Convert ÷ sign into multiplication, that will turn 2/3 into 3/2
3/5 X 2/3
Divide by 3
3/5 by 3
1/5
2/3 by 3
2/1
1/5 X 2/1
2/5
The # in decimal form would be A
Both sides are equal, so the equation has infinite solutions.
25 - 4x = 15 - 3x + 10 - x
= 25 - 4x = 25 - 3x - x
= 25 - 4x = 25 - 4x
