One idea is:
Paul wants to buy an iphone X. He has savings of $100 to start with. Local McDonalds pays $7 per hour (after tax) to students on summer break for helping out at the counter. The iphone costs $1000. At least how many hours does Paul need to work at McDonalds to be able to afford the iphone.
So, that matches ax+b>c in that
a is the hourly earning
b is the initial savings
c is the price of the iphone

Step-by-step explanation:
Using <em>cos</em> and <em>sin</em> you are able to find the height of the ladder from the bottom of the house to the place the top of the ladder is. You can do this by making a triangle. By using the lengths and angles already present you are able to find all angles of the triangle.
Answer:In this case, if you substitute x = 10 into the equation you will find that y must be 41 ... f(x)= 4x + 1 is written in function notation and is read “f of x equals 4x plus 1
Step-by-step explanation:
This is a systems of equation problem.
First, set up the equation.
814=w+d w=d-36
Second, insert w= in for w in the equation.
814=d-36+d
Third, combine like terms.
814=2d-36
Fourth, solve the equation by adding 36 and dividing by 2 to both sides.
814=2d-36
+36 +36
___________
850=2d
----- ----
2 2
__________
425=d
So the dryer (d) costs $425.
