Mimi owes the bank a little less than $20. Which choice could be her balance?

1 answer:

7 0

The answer is c.

owing the bank means she has a NEGATIVE balance. therefore, choices (a) and (d) are wrong.

(b) is negative, but the absolute value of -20.75 is 20.75. this would mean that she owes the bank 20.75, but this cannot be right as that is more than 20.

(c)'s absolute value is 19.75, which is a little less than 20.

If a ∝ b and a = 18 when b = 3, then find a when b = 5.

Elden [556K]

"a ∝ b" means "a is proportional to b", which in turn means there is some constant k such that

a = kb

We're given that a = 18 and b = 3, so that

18 = 3k ⇒ k = 6

Then when b = 5, we would have

a = 6 × 5 = 30

madreJ [45]

Answer:

5x³ - 2x²

Step-by-step explanation:

Step 1: Write out expression

4x³ - x² + 4x + x³ - x² - 4x

Step 2: Combine like terms (x³)

5x³ - x² + 4x - x² - 4x

Step 3: Combine like terms (x²)

5x³ - 2x² + 4x - 4x

Step 4: Combine like terms (x)

5x³ - 2x²

What is the answer?

Bad White [126]

Answer:

k=3

Step-by-step explanation:

+ we note f(p)= $p^{4}+p^{2} +p -k$

+ Because of "p-1 is a factor of f(p)", that means f(p)= (p-1)* g(p)

Then we have f(1)= (1-1)*g(1)= 0* g(1)= 0

+ We replace p=1 in f(p) and we have:

f(1)=0

that means: $1^{4}+1^{2} + 1 - k=0$

then 1+1+1-k = 0, 3-k=0 or k=3

Hope that useful for you.
