2 years is the same as 24 months, so the equation would be:
685 = 24x + 85, where x is the monthly fee.
600 = 24x
600/24 = x
x = 25
The monthly fee is $25.
-16t² + 180t
-16(2)² + 180(2)
-64 + 360
The fireworks height after 2 seconds is 296 feet
2 students more were introducced in the class and each group had 8 people
Answer:
x²/9 − (y + 1)²/81 = 1
Step-by-step explanation:
-2y − 82 + 9x² = y²
9x² = y² + 2y + 82
9x² = y² + 2y + 1 + 81
9x² = (y + 1)² + 81
9x² − (y + 1)² = 81
x²/9 − (y + 1)²/81 = 1
$650-100=$550
30x=550 where x is number of weeks
divide each side by 30
x=18.33 weeks so 19 weeks
Hope that helps.
