Substitution is where you place a number instead of a letter. If you they give you a question let’s say “what is he value of x when x=5”
And he equation is
8x=40 (super easy equation but oh well)
So you “substitute” the x
So it will be
8*5=40
Hope this helped and I’m not sure if I made any sense at all but I tried

Pablo graphs a system of equations. One equation is quadratic and the other equation is linear. What is the greatest number of p
Nady [450]
For this case we have the following type of equations:
 Quadratic equation:
 y = ax ^ 2 + bx + c

 Linear equation:
 y = mx + b

 We observe that when equating the equations we have:
 ax ^ 2 + bx + c = mx + b

 Rewriting we have:
 ax ^ 2 + (b-m) x + (c-b) = 0

 We obtain a polynomial of second degree, therefore, the maximum number of solutions that we can obtain is 2.
 Answer:
 The greatest number of possible solutions to this system is:
 c.2

( this is my summer math homework, please help!)
Ilia_Sergeevich [38]

Using proportions, the selling prices are given as follows:

1. $46.92.

2. $15.29.

3. $17.16.

4. $20,280.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

To find the selling prices, we have to multiply the original prices by either 1.02(2% sales tax) or 1.04(4% sales tax), hence they are given as follows:

  • 1. 46 x 1.02 = $46.92.
  • 2. 14.99 x 1.02 = $15.29.
  • 3. 16.50 x 1.04 = $17.16.
  • 4. 19500 x 1.04 = $20,280.
