Step-by-step explanation:
☆Remember: 
☆Slope-intercept: 
---
☆We need to find the slope first. So just plug in according to the slope formula!

---
☆Now we need to find the y-intercept. We are going to plug in the slope and a set of coordinates to find the y-intercept.

---
☆Now all we need to do is plug in and we are done!

In general, you identify the terms containing the variable. Then figure out what is being done to the variable. Here, it is multiplied by 1/2 and then 3 is subtracted. You undo these operations in reverse order.
Undo the subtraction of 3 by adding 3. Undo the multiplication by 1/2 by multiplying by its inverse, 2. Of course, the rules of equality tell you that anything you do to one side of the equation must also be done to the other side.
You can consider it as "unwrapping the package". You start at the outside, the last operation applied, and work your way in.
Answer:
Step-by-step explanation:
the way it is written, the answer is
5x^2 - 6x + 2 + 19x - 7
5x^2 + 13x - 5 is the answer.
However I suspect you mean
5x^2 - 6x + 2 + 9x^2 + 10x - 7
14x^2 + 3x - 5 is the answer if the revision I've made is correct.
First, lets figure out how many pencils we will need. so we can do that by 4 pencils x 28 children and we get 112. Then if there are 8 pencils in a package, we divide 112 by 8 and get 14
