Which of the following are possible equations of a parabola that has no real solutions and opens downward?
y > = -(x + 4)2 - 2
y > = -(x + 4)2 + 2
y > = -x2 - 2
y > = (x - 4)2 + 2
y > = -(x - 4)2 - 2

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

step-by-step explanation:

answer is because 4×10=40

and 98×4= is 392

40,392

hope this !
