Please show the work/explain. I need to write it down.
Maksim231197 [3]

9514 1404 393

Answer:

  • 20 months
  • $5500

Step-by-step explanation:

There are a couple of ways to work a problem like this. You have probably been taught to write equations for each of the payment amounts as a function of time, then equate those values to solve for the time that makes them equal.

  at dealer 1, the total amount paid (y) will be a function of months (x):

     y = 2500 +150x

  at dealer 2, the corresponding equation is ...

     y = 3000 +125x

These are equal when ...

  y = y

  2500 +150x = 3000 +125x

  25x = 500 . . . . . . . . . subtract 125x +2500 from both sides

  x = 500/25 = 20

The total paid will be the same after 20 months.

That amount is ...

  y = 2500 +150(20) = 5500

$5500 will be paid to either dealer after 20 months.

__

The other way to work the problem is to "cut to the chase". The difference in down payment is made up at the rate of difference in monthly payments. So The number of monthly payments (x) required to equal the difference in down payments is ...

  25x = 500 . . . . . . . . . you may recognize this equation from above

  x = 500/25 = 20

Help please, what’s: 5x-7+2-2x=-26
svetoff [14.1K]

Answer:

7

Let's solve your equation step-by-step.

5x−7+2−2x=−26

Step 1: Simplify both sides of the equation.

5x−7+2−2x=−26

5x+−7+2+−2x=−26

(5x+−2x)+(−7+2)=−26(Combine Like Terms)

3x+−5=−26

3x−5=−26

Step 2: Add 5 to both sides.

3x−5+5=−26+5

3x=−21

Step 3: Divide both sides by 3.

3x

3

=

−21

PLEASE PLEASE PLEASE HELP I really don’t understand this.
Amiraneli [1.4K]

Answer:

The second option is the answer.

Step-by-step explanation:

Do f(x) first, and then plug that into g(x).

f(x)=\sqrt{x+3}

(g o f)(x) = \frac{\sqrt{x+3}^{2}+2 }{\sqrt{x+3}}=\frac{x+5}{\sqrt{x+3}}
