Answer:
1/5 · 1/5 · 1/5 · 1/5
Step-by-step explanation:
One way of interpreting exponents is as repeated multiplication. When you see (1/5)⁴, you can read that as "4 copies of 1/5, multiplied together." That expansion looks like (1/5)⁴ = 1/5 · 1/5 · 1/5 · 1/5

the number of dimes=50-y
if the number of dimes represents x, the equation would be
y=50-x
Final answer:
The number of dimes that Lindsey has can be represented by the algebraic expression 50 - y, where y is the number of quarters.
Explanation:
Lindsey has a total of 50 coins which are either dimes or quarters. Let y represent the number of quarters Lindsey has. That means the total number of coins, 50, is the sum of the number of quarters (y) and the number of dimes (we'll call this x). So, we can write this equality as x + y = 50, where x is the number of dimes. We want an algebraic expression for x, the number of dimes, in terms of y, the number of quarters. From the equation above, we can solve for x: x = 50 - y. Therefore, the number of dimes Lindsey has in terms of the number of quarters is 50 - y.

C) C = –1.25w + 12.50
D) C = –1.25w – 12.50
Answers
For this case we have a function of the form:
Where,
- b: initial amount
- m: weekly rate of change
- w: number of weeks
- c: total balance
We have then that Avery has a total of $ 12.50 in her piggy bank at home:
Each week she takes out $ 1.25 to ride the city bus:
Substituting values we have:
Answer:
an equation representing the balance, C, in the piggy bank, where w is the number of weeks is:
Option C
bus=number of weeks times how much taken out each time
12.5=amount now
bus=1.25w
C=12.50-1.25w
or
C=-1.25w+12.5
answer is C

Answer: (x - 2)(x² + 2x + 4)
Step-by-step explanation: In this problem, we're asked to factor x³ - 8.
Notice that x³ is a perfect cube and 8 is a perfect cube because 8 is 2 × 2 × 2 or 2³. So we have the difference of two cubes.
To factor the difference of two cubes, we use the following formula.
a³ - b³ can be factored as (a - b)(a² + ab + b²) and in this problem, since a³ is represented by x³, the value of a is x and since b³ is represented by 8, the value of b is 2.
So substituting x and 2 into the formula for a and b, we have
[(x) - (2)][(x)² + (x)(2) + (2)²] and notice that we changed the parentheses in the formula to brackets so that we're not dealing with too many sets of parentheses.
Next, simplifying inside the second set of brackets and changing the brackets back to parentheses, we have (x - 2)(x² + 2x + 4) which is our final answer.
