Answer:

1x+2=8+-1​

1+2=7

(x+2) + (-2) = 7 (-2)

x + 2-2=7-2

x=5

Explanation:

  • <em>Number 1  as a factor, does not need to be explicitly written.</em>
  • <em>In our example, the above transformation has been applied once.</em>
  • <em>In order to solve this linear equation, we need to group all the variable terms on one side, and all the constant terms on the other side of the equation.</em>
  • <em>In our example,  term 2 , will be moved to the right side.  </em>
  • <em>Notice that a term changes sign when it 'moves' from one side of the equation to the other.</em>
  • <em>We need to get rid of expression parentheses.</em>
  • <em>If there is a negative sign in front of it, each term within the expression changes sign.</em>
  • <em>Otherwise, the expression remains unchanged.</em>
  • <em>In our example, there are no negative expressions.</em>
  • <em>Numerical terms in this expression have been added.</em>

A clothing store advertises that it is having a 25% off sale. for one day only, the store advertises and additional savings of 1
kogti [31]

Let assume x be the sale price

A clothing store advertises that it is having a 25% off sale.

The sale price with 25% discount is f(x) = sale price - 25% of sale price

f(x)= x - 0.25x = 0.75x

For one day only, the store advertises and additional savings of 10%.

The sale price with 10% discount is g(x) = sale price - 10% of sale price

g(x)= x - 0.10x = 0.90x

Use composition function

g(f(x)) = g( 0.75x) = 0.90(0.75x) = 0.675x

That is 0.675/100 = 67.5%

The total percent discount = 100% - 67.5% = 32.5%

what would be the sale price of a $40 sweater?

Here sale price x= 40

So we plug in 40 for x

g(f(40)) = g( 0.75(40)) = 0.90(0.75(40)) = 0.675(40) = 27

The sale price of sweater = $27
