a. 3x - 7y = -14 b. y - 4 = -1/4 (x+4) c. y + 5 = 3 (x+2) d. y = -7x + 2

Answers

Answer:

A and D

Step-by-step explanation:

a.

3x - 7y = -14

-7y = -3x -14

y = 3/7x + 2

b.

y - 4 = -1/4 (x + 4)

y - 4 = -1/4x -1

y = -1/4x + 3

c.

y + 5 = 3 (x + 2)

y + 5 = 3x + 6

y = 3x + 1

3y + 2 = 4x , x+ 5y = 3 what is the solution to the system of equations shown above? (in fraction form)

Answers

We have x+5y=3 => x= 3-5y
So 3y+2=4x
<=>3y+2=4(3-5y)
<=>3y+2=12-20y
<=>3y+20y=12-2
<=>23y=10
<=>y=10/23 => x=3-5(10/23)=19/23

Ok done. Thank to me :>

Answer:

19/23, 50/23

Step-by-step explanation:

We can take the first equation and isolate the x:

x + 5y = 3 ⇒ -5y ⇒

x = 3 - 5y.

Then we can substitute the x in the first equation by this:

3y + 2 = 4(3-5y) ⇒

3y + 2 = 12 - 20y ⇒ +20y

23y + 2 = 12 ⇒ -2

23y = 10 ⇒ ÷23

y = [tex]\frac{10}{23}[/tex]

Then we can add the value of y into the equation equaling x we made:

x = 3 - 5([tex]\frac{10}{23}[/tex]) ⇒

x = 3 - [tex]\frac{50}{23}[/tex] ⇒

x = [tex]\frac{19}{23}[/tex]

Hope this helps! :)

A scrapbooking store is selling rubber stamps for four dollarsand $4.95 each. The total sales F(n) is a function of the number of rubber stamps n sold
A. Identify the independent and dependent variables
B. What values of the domain and range make sense for this situation? explain
C. Write a function to represent the total sales. Then determine the total sales for five stamps

Answers

A. Independent variable: number of rubber stamps n sold. Dependent variable: F(n), the total sales.

B. Only whole numbers. It is impossible to have negative and/or fractional stamps.

C. F(n) = $4.95n, which is 4.95 times n.

So, plugin 5 for n
