Answer:
4x-90(3)=50%m
Step-by-step explanation:
m= marbles (take note of my user name
16.6 with a line on top of 6. When you divide 50 by 3 you get 16.6 a repeating decimal.you would round and get 17. I think it's correct!!
Ok 15% is 0.15 in decimal form so you multiply 0.15 by 16000$ and get 2,400$ (the down payment not amount owed) you then subtract 2,400$ from 16,000$ and get 13,600$ which is how much he still owes
Answer:
a = 2, b = - 3, c = - 8
Step-by-step explanation:
Expand f(x) = a(x + b)² + c and compare coefficients of like terms, that is
a(x + b)² + c ← expand (x + b)² using FOIL
= a(x² + 2bx + b²) + c ← distribute parenthesis by a
= ax² + 2abx + ab² + c
Compare like terms with f(x) = 2x² - 12x + 10
Compare coefficients x² term
a = 2
Compare coefficients of x- term
2ab = - 12, substitute a = 2
2(2)b = - 12
4b = - 12 ( divide both sides by 4 )
b = - 3
Compare constant term
ab² + c = 10 , substitute a = 2, b = - 3
2(- 3)² + c = 10
18 + c = 10 ( subtract 18 from both sides )
c = - 8
Then a = 2, b = - 3, c = - 8
Example:
12+24
GCF:
12: 1,2,3,4,6,12
24: 1,2,3,4,6,8,24
Common factors: 1,2,3,4,6
Greatest factor: 6
Divide:
12 divided 6= 2
24 divided 6= 4
12+24= 6x(2+4)
