Katena32 [7]
Daniel spent $4.75 for a lunch and $1.85 for a snack
$4.75+$1.85=$6.6, so Daniel spent $6.6 total

Kyle spent $5.75 for lunch and $1.00 for a snack
$5.75+$1.00=$6.75, so Kyle spend total $6.75.

Final step:
$6.75-$6.6=$0.15. As a result, Kyle spent $0.15 or 15 cent more than Daniel. Hope it help!

What is the equation of the parabola?
Neporo4naja [7]

Answer:

y = -1/8 x² + 5

Step-by-step explanation:

Parabola opens vertically and vertex (h,k) = (0,5), pass point (4,3)

basic formula: y = a(x - h)² + k

y = a (x-0)² + 5

y = ax² + 5         pass (4,3)

3 = 16a + 5

a = (3-5)/16 = -1/8

equation: y = -1/8 x² + 5

check: pass another point (-4,3)

-1/8 * (-4)² + 5 = -2 + 5 = 3
