Answer:
Step-by-step explanation:
<u>Total earning:</u>
- Salary + commission + extended warrant fee
- 2300 + 0.03*44000 + 41*8 =
- 2300 + 1320 + 328 =
- 3948
x^2-9x-6=0
Use the quadratic formula to get (9+sqrt(105))/2 or (9-sqrt(105))/2
#2: Her earnings were no more than $64. Let e represent her earnings. E is less than or equal to 64 (since it says no more than $64).
e ≤ 64.
#4: A checking account was no more than $500. Let a represent the amount in the checking account. A is less than or equal to 500.
a ≤ 500.
#5: Max. ceiling height of 8 ft is required. Let f represent length in feet. Length in feet has to be less than or equal to 8.
f ≤ 8.
#6: Min. number of 12 participants required. Let n represent the number of participants. There has to be at LEAST 12 participants. So, the number of participants has to be greater than or equal to 12.
n ≥ 12.
Answer:
B) 12
Step-by-step explanation:
(9y + 7)° + (7y - 19)° = 180° (interior angles in the same side of transversal)
(9y + 7 + 7y - 19)° = 180°
(16y - 12)° = 180°
16y - 12 = 180
16y = 180 + 12
16y = 192
y = 192/16
y = 12
