6 0

Answer:

one solution (0,-1)

Step-by-step explanation:

y=5x-1

-15x-3y=3

LEts solve for x  and y, Substitute  5x-1 for y in second equation

-15x-3y=3

-15x-3(5x-1)=3

-15x-15x+3=3

Combine like terms

-30x+3=3

Subtract 3 on both sides

-30x=0

Divide both sides by -30

x=0

Now plug in 0 for x in first equation

y=5x-1

y=5(0)-1=-1

So one solution (0,-1)

A rental car company is running two specials. Customers can pay $40 to rent a compact car for the first day plus $6 for each add
Flura [38]

Answer: she wants to rent the car for 11 days.

Step-by-step explanation:

Let x represent the number of additional days that Pamela wants to rent the car for.

Customers can pay $40 to rent a compact car for the first day plus $6 for each additional day. This means that the total cost of using this special for x days would be

40 + 6(x - 1) = 40 + 6x - 6

= 34 + 6x

Also, they can rent the same car for $30 the first day and $7 for every additional day beyond that. This means that the total cost of using this special for x days would be

30 + 7(x - 1) = 30 + 7x - 7

= 23 + 7x

Since she found out that the two specials are equivalent for x days, then

34 + 6x = 23 + 7x

7x - 6x = 34 - 23

x = 11

myrzilka [38]

Answer:

She have to pay the bank at the end of the 6 years = 222000$

Step-by-step explanation:

Formula applied in this case where price, interest rate and time duration is mentioned.

Interest = prt/100

Substituting all the given values in the formula.

interest = 15000 * 6 * 8/100

150 * 6 * 8 = 7200

Interest + 15000 = 15000 + 7200 = 222000$ has to pay the total.

In this question amount is 15000 multiply by 6 and by 8 then divide it by 100 so we get the interest then we add it in to amount so we get an answer that is total amount which he has to pay.                                                                           Hope this helps! :P PLZ GIVE ME BRAINLIST
