The opposite expression of "-2a + 5c" is "5c - 2a".

To rewrite the expression "-2a + 5c" using the guidelines opposite, we will reverse the steps taken to simplify the expression.

Reverse the order of the terms: 5c - 2a

Reverse the sign of each term: 5c + (-2a)

After following these guidelines, the expression "-2a + 5c" is rewritten as "5c + (-2a)".

Let's break down the steps:

Reverse the order of the terms

We simply switch the positions of the terms -2a and 5c to get 5c - 2a.

Reverse the sign of each term

We change the sign of each term to its opposite.

The opposite of -2a is +2a, and the opposite of 5c is -5c.

Therefore, we obtain 5c + (-2a).

It is important to note that the expression "5c + (-2a)" is equivalent to "-2a + 5c".

Both expressions represent the same mathematical relationship, but the rewritten form follows the guidelines opposite by reversing the order of terms and changing the sign of each term.

By using the method subtraction,

1 quarter is 0.25

1 nickel is 0.05

To subtract in mathematics is to take something away from a group or a number of objects. The group's total number of items decreases or becomes lower when we subtract from it. The components of a subtraction issue are the minuend, subtrahend, and difference. An arithmetic operation called subtraction simulates the process of deleting items from a collection. The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.

Given that,

Isaac has 18 coins, all quarters and nickels.

The total value of the coins it $3.50.

Let the quarters be x and nickels be y

x+ y= 18

x= 18 - y... equation 1

1 quarter is 0.25

1 nickel is 0.05

So,

0.25x+ 0.05y= 3.50

substitute x value in above equation

0.25(18-y)+0.05 = 3.50

4.5-0.25y+ 0.05 = 3.50

4.55 - 3.50 = 0.25y

1.05= 0.25y

y= 4.2

y in equation 1

x= 18 - y

x= 18-4.2

x= 13.8

We find the value of the remainder by replacing:

x - 11 ⇒ x = 11

in the equation:

Then, the remainder if we divide the polynomial by (x - 11) is -11. This means that it cannot be a factor, since the remainder is not 0.

In the given formula we have variables:

If we have to solve it for P then it should be called 'Principal' or 'Loan amount'.

If we have to solve it for n then it should be called 'Number of payments' or 'Number of installments'.

Since n is the power of a number we need logarithm to solve it for n.

Answer:

"Principal (loan amount)"

"Term of the loan (in months)" or "Number of monthly payments"

Logarithms

Step-by-step explanation:

Monthly Payment Formula

\(M=\dfrac{Pr\left(1+r\right)^n}{\left(1+r\right)^n-1}\)

where:

If we solve for P, the name of the formula is "Principal (loan amount)".

If we solve for n, the name of the formula is "Term of the loan (in months)" or "Number of monthly payments".

When solving for n, we need to use logarithms:

\(\boxed{\begin{aligned}M&=\frac{Pr\left(1+r\right)^n}{\left(1+r\right)^n-1}\\\\M(\left(1+r\right)^n-1)&=Pr\left(1+r\right)^n\\\\\frac{\left(1+r\right)^n-1}{\left(1+r\right)^n}&=\frac{Pr}{M}\\\\1-\frac{1}{\left(r+1\right)^n}&=\frac{Pr}{M}\\\\\frac{1}{\left(r+1\right)^n}&=1-\frac{Pr}{M}\\\\\left(r+1\right)^{-n}&=1-\frac{Pr}{M}\\\\\ln \left(r+1\right)^{-n}&=\ln \left(1-\frac{Pr}{M}\right)\\\\-n\ln(r+1)&=\ln\left(1-\frac{Pr}{M}\right)\\\\n&=\frac{-\ln\left(1-\frac{Pr}{M}\right)}{\ln(r+1)}\end{aligned}}\)

Amelia was at camp for 6 days. The equation used to determine how many days(D) she was at camp is C x D = 6D and S - (C x D) = E

Given data:

S = initial amount = $54

D = the number of days

C = the cost per day = $6

E: the ending amount = $18

Amelia started with S=$54 and spent C=$6 each day at camp.

Therefore, the total amount she spent at camp is given in an algebraic expression that states the product of two variables:

C x D = 6D

Next, she ended with E=$18. So, the equation can be written in algebraic expression that states the difference between the variable:

S - (C x D) = E

Substituting the values in the equation we get:

54 - 6D = 18

54 - 18 = 6D

36 = 6D

D = 6

Therefore, Amelia was at camp for 6 days.

The amount of money that I will have at the end of 20 years would be =$4,480. That is option D

Compound interest is defined as the interest that is being earned on an account which is based on the rate and the time the investment was made.

The total amount invested (p)= $2,000

The rate of investment (r) = 5%

The time of investment(t)= 12 year

The compound interest warm from that account;

= P×T×R/100.

= 2,000×12×5/100

= 120000/100

= $1200

For the next 8 years with the rate of 8% ;

= 2,000×8×8/100

= 128000/100

= $1280

The total compound interest = $1200+$1280= $2,480

Therefore, the amount of money that I will have at the end of 10 years would be = 2000+2480 = $4,480

Answer:

d=12

Step-by-step explanation:

divide 84 by 7

Answer:

2, -2, and 0.

Explanation:

First, we need to factorize the left side of the equation as:

(x² + 4)² + 32 = 12x² + 48

(x² + 4)² + 32 = 12( x² + 4)

Now, we need to substitute a = x² + 4, so:

a² + 32 = 12a

So, solving for a, we get:

a² + 32 - 12a = 12a - 12a

a² + 32 - 12a = 0

a² - 12a + 32 = 0

(a - 8)(a - 4) = 0

Then:

a - 8 = 0

a - 8 + 8 = 0 + 8

a = 8

or

a - 4 = 0

a - 4 + 4 = 0 + 4

a = 4

Then, a is equal to x² + 4, so replacing a by x² + 4 on each solution for a, we get:

For a = 8:

x² + 4 = 8

x² + 4 - 4 = 8 - 4

x² = 4

x = ±√4

x = ± 2

For a = 4:

x² + 4 = 4

x² + 4 - 4 = 4 - 4

x² = 0

x = 0

Therefore, the solutions for x are 2, -2, and 0.

We are given two numbers to use \(4\frac{1}{12}\) (Houston to Dallas) & \(3\frac{1}{3}\) (San Antonio to Houston).

When a single arithemetic / logic unit (alu), which does the math in a processor, is given 2 independent register sets so that it can quickly alternate between running 2 separate threads, we call it simultaneous multithreading.

Simultaneous multithreading, or "SMT," is the term used when a single Arithmetic/Logic Unit (ALU) is given two independent register sets to swiftly switch between operating two distinct threads.

SMT is a technique used in processor design to improve overall performance by allowing multiple threads to be executed concurrently on a single physical processor core. It enables the ALU to switch between different threads, or sets of instructions, rapidly, providing the illusion of simultaneous execution and effectively utilizing the available resources.

The probability of winning $1000 a day for life is approximately 5.245 x 10^-11 and the probability of winning $1000 a week for life is approximately 1.07 x 10^-8. The probability of winning the jackpot ($1000 a day for life) is 1/(60^5 * 4), while the probability of winning $1000 a week for life is 1/(60^5).

In the Florida Lottery Cash4Life game, a player must select five numbers from 1 to 60 and then one Cash Ball number from 1 to 4. The jackpot prize is $1000 a day for life if all five numbers and the Cash Ball match the winning numbers drawn on Monday nights. If just all five numbers match the winning numbers, the player will win $1000 a week for life.
To determine the probability of winning $1000 a day for life, we can use the formula for the probability of independent events: P(A and B) = P(A) x P(B)

(a) To win the jackpot of $1000 a day for life, the player needs to match all five numbers and the Cash Ball. There are 60 options for each of the five numbers and 4 options for the Cash Ball. The total number of possible outcomes is 60^5 (60 choices for each of the five numbers) times 4 (for the Cash Ball). So the probability of winning the jackpot is 1/(60^5 * 4). (b) To win $1000 a week for life, the player needs to match only the five numbers, without considering the Cash Ball. The total number of possible outcomes for this scenario is 60^5. Therefore, the probability of winning $1000 a week for life is 1/(60^5).
