9. Jamie threw a softball that traveled along a path described by the parabola y = - x2 + 10x, where x is the horizontal distance in feet that the ball has traveled from Jamie and y is the height of the softball in feet. What is the ball's horizontal distance from Jamie when it is 24 feet up in the air? Solve the problem algebraically. Only one of your solutions makes sense. Why?

3; 9 is 8 to -4

step-by-step explanation:

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
