1000 x .085 x 3 = 255
answer is <span>A: $255</span>
Answer:
8,000 - 24x
Step-by-step explanation:
Let
y ----> depreciated value of the car
x---> rate of depreciation
t ----> the time in months
we know that
The linear equation that represent this situation is
y=8,000-xt
For
t=2 years=2*12=24 months
substitute
y=8,,000-x(24)
y=8,000-24x
Hello!!
Obviously, there are many possibilities for a real world problem. But, here's one option.
"Jeanette owes her friend, Debbie, a sum of money that is a multiple of 8. During the summer, Jeanette earns 60 dollars by selling cookies at a bake sale. After paying Debbie back for the borrowed sum of money, Jeanette has 28 dollars left. What was the sum of money divided by 8 that Jeanette owed Debbie?"
Hope this helps!! Let me know if you have ANY questions.
Population density = population/area
Califonia = 36,500,000 / 163,707 = 223.0 persons per square mile
Florida = 18,300,000 / 65,758 = 278.3 persons per square mile
Iowa = 2,990,000 / 56,276 = 53.1 persons per square mile
New Jersey = 8,690,000 / 8,722 = 996.3 persons per square mile
Wyoming = 522,000 / 97,818 = 5.3 persons per square mile
Answer:
<h3>D. -1, 1</h3>
Step-by-step explanation:
If x-1 is a factor of x⁴ + 2x³ - 2x - 1, then x-1 =0 is a factor
if x-1 = 0
x = 1
To get other factors we will divide the polynomial by x-1
Find the division in the attachment
x⁴ + 2x³ - 2x - 1,/x-1 = x³ +3x²+ 3x + 1,
let x = -1 be a factor of the resulting expression
f(-1) = (-1)³ +3(-1)²+ 3(-1) + 1
f(-1) = -1 +3(1)-3 + 1
f(-1) =-1+1-3+3
f(-1) = 0
Since f(-1) =0, hence x+1 is a factor of the resulting polynomial'
Dividing x³ +3x²+ 3x + 1, by x+1 to reduce the power of the polynomial
x³ +3x²+ 3x + 1/x+1 = x²+2x+1
Factorizing x²+2x+1
= x²+2x+1
=x²+x+x+1
= x(x+1)+1(x+1)
= (x+1)(x+1)
if the function is equal to zero
x+1 = 0 and x+1 = 0
x = -1 twice
Hence the solutions to the polynomial are 1 and -1(three times)
