Answer:
C
Step-by-step explanation:
x^3+4x^2-9x-36=0
or x²(x+4)-9(x+4)=0
or (x+4)(x²-9)=0
or (x+4)(x+3)(x-3)=0
x=-4,-3 or 3
Answer:
Total amount spend = $6.96
Step-by-step explanation:
Given:
Amount of Skittles = 1.5 pound
Amount of Reese = 4.5 pound
Amount of chips = 2.3 pound
Candy cost = $0.70 per pound
Chips cost = $1.20 per pound
Find:
Total amount spend
Computation:
Total amount spend = [Amount of Skittles+Amount of Reese][Candy cost]+[Amount of chips][Chips cost]
Total amount spend = [1.5+4.5][0.70]+[2.3][1.20]
Total amount spend = 4.2 + 2.76
Total amount spend = $6.96
Let y be the temperature
Let m be the rate of temperature drop in degrees per hour
Let x be the number of hours elapsed since 8PM
The initial temperature (at x = 0) is 0
y = mx
Four hours from 8 PM, the temperature was -16.8 degrees
-16.8 = m(4)
m = -4.2 degrees per hour
At 9PM, one hour will have elapsed.
y = -4.2(1)
y = -4.2 degrees
