Answer:

on the 5th week they would both have the same amount of money they would both have a total of 85$

Step-by-step explanation:

The number of weeks will pass before Michelle and Pierre have the same amount of money will be 5.

The solution of the equation means the value of the unknown or variable.

Let x be the number of the weeks and y be the total amount.

Michelle and Pierre both want to buy guitars, Michelle has already saved $60, and plans to save $5 per week until she can buy the guitar, Pierre has $25, and plans to save $12 per week.

Then the equations will be

y = 5x + 60    ....1

y = 12x + 25  ....2

Subtract equation 1 from equation 2. Then we have

7x – 35 = 0

       7x = 35

         x = 5 weeks

Then the number of weeks will pass before Michelle and Pierre have the same amount of money will be 5.

Answer:

f(x)=x^2+4x-21

Step-by-step explanation:

Answer:

f(x) = (x + 7)  (x - 3)

Step-by-step explanation:

f(x)=(x+[tex]2)^{2}[/tex]-25

(x + 7) (x - 3) we put the 2 x's because of the (x+2)^2

now the + 7 and - 3, multiply the 2 numbers = -21 then use those 2 in

(x+2)^2 to add for the answer = -25

Answer:

A: 57

Step-by-step explanation:

We are told that;

When x = 7, log y = 1.755

Since we want to find the value of y when x = 7, and the log function is in base 10, we will just use anti log to solve for y in the equation.

Thus;

Log₁₀y = 1.755

y = 10^(1.755)

y = 56.89

Approximating to a whole number gives;

y = 57

Answer:

8, 6, 3, 2, 1

Step-by-step explanation:

g(x) = -x + 3

using g(x),

g(-5) = (-1 x -5) + 3

= 5 + 3

= 8

g(-3) = (-1 x -3) + 3

= 3  + 3

= 6

g(0) = 0 + 3

= 3

g(1) = -1 + 3

= 2

g(2) = -2 + 3

= 1

Answer:

FV= $10,342.64

Step-by-step explanation:

Giving the following information:

Initial Investment (PV)= $2,500

Interest rate (i)= 0.095/12= 0.00792

Number of periods (n)= 15*12= 180

To calculate the future value (FV), we need to use the following formula:

FV= PV*(1 + i)^n

FV= 2,500*(1.00792^180)

FV= $10,342.64

Answer:

Simplifying radicals is the process of manipulating a radical expression into a simpler or alternate form. Generally speaking, it is the process of simplifying expressions applied to radicals.

Estimation (or estimating) is the process of finding an estimate, or approximation, which is a value that is usable for some purpose even if input data may be incomplete, uncertain, or unstable. The value is nonetheless usable because it is derived from the best information available.

Step-by-step explanation:

The radical symbol represents the root of a number and is read as x radical n or the nth root of x.

The symbol " that expresses a number's root is known as radical, and it is read as x radical n or the nth root of x. The horizontal line that surrounds the number is known as the vinculum, and the number beneath it is known as the radicand. The index or degree is the number n written before the radical.

The process of transforming a radical expression into a simpler or alternate form is known as simplifying radicals. In general, it is the process of simplifying expressions that are applied to radicals.

Estimation (or estimating) is the process of determining an estimate, or approximation, which is a value that can be used for a specific purpose despite the fact that the input data may be incomplete, uncertain, or unstable. The value is still useful because it is based on the best available information.
