Answer:

x = 10/3 , y = 25/3

Step-by-step explanation:

Let's solve your system by substitution.

5x−2y=0 ; 5x+10y=100

<u>Step 1: </u>Solve 5x−2y=0 for x:

5x−2y=0

5x−2y<u>+2y</u>=0<u>+2y</u> (Add 2y to both sides)

5x=2y

5x=2y

5x/5=2y/5 (Divide both sides by 5)

x=2y/5 (Simplify)

<u>Step 2:</u> Substitute 2y/5 for x in 5x+10y=100:

5x+10y=100

5 2/5y +10y=100

12y=100 (Simplify both sides of the equation)

12y/12=100/12 (Divide both sides by 12)

y=25/3

<u>Step 3:</u> Substitute 25/3 for y in x=2/5y

x=2/5y

x=2/5 * 25/3

x=10/3 (Simplify both sides of the equation)

<u>At the end we have the following answers : </u>

x = 10/3

y = 25/3

P (n), given below, is the price P in dollars for n grams of vitamins.P(n)=0.4n+5.7Complete the following statements.
Amanda [17]

(a)

In the function P(n) = 0.4n +5.7, P(n) is price of n grams of vitamins. So for the function x = P(n); x is price of n grams of vitamins.

The inverse of function determine amount of the vitamins for the known price of x dollars. So answer is,

The amount of vitamins (in grams) for a price of x dollars.

(b)

Let P(n) = x, So

x=0.4n+5.7

Replace n by x and x by n in the given equation.

n=0.4x+5.7

Simplify the equation for x.

\begin{gathered} n+0.4x+5.7 \\ n-5.7=0.4x \\ x=\frac{n-5.7}{0.4} \\ =\frac{10n-57}{4} \end{gathered}

So inverse of function is after interchange of variables,

P^{-1}(x)=\frac{10x-57}{4}

(c)

Substitute 8.3 for x in the inverse equation to obtain the valur of P^-1(8.3).

\begin{gathered} P^{-1}(8.3)=\frac{10\cdot8.3-57}{4} \\ =\frac{83-57}{4} \\ =\frac{26}{4} \\ =6.5 \end{gathered}

So answer is 6.5.

How wil the graph of the function y=x^3 transform when changed to y=x^3+4
dem82 [27]

Every point on the original graph will move up 4 units. See the enclosed graph

Legend

Red: y = x^3

Blue: y = x^3 + 4

Green: A vertical line that shows that when x = 1 on the original red graph, x = 5 on the blue.

What equation best represents the circumference of a circle with a radius of 6 feet? A y = 2π B y = 6π C y = 12π D y = 16π
professor190 [17]

Answer:

12π

Step-by-step explanation:

The circumference is the distance you need to walk to do 1 full rotation of a shape. The formula to calculate the circumference of a circle will be

circumference =2πr

where π is a constant that equal to 3.14 or 22/7 and r is the radius of the circle (radius = 6 feet).

The circumference of this circle will be:

circumference =2πr

circumference =2π(6)

circumference =12π
