John needs a plumber to repair the kitchen drain. The plumber charges $85 for the parts that he will need for the repair plus $30 for each hour worked. The maximum amount of money john can spend is $250. Which inequality would represent this situation if x is the number of hours worked?

Answers

Answer:

[tex]30x+85y\leq 250[/tex]

Step-by-step explanation:

Cost of each part is [tex]\$85[/tex]

Cost of working one hour is [tex]\$30[/tex]

Let number of hours worked be [tex]x[/tex] and

The maximum amount of money that John can spend is [tex]\$250[/tex].

From the question we have

[tex]30x+85y\leq 250[/tex]

The required inequality is [tex]30x+85y\leq 250[/tex].

Answers

Given:

The function is

[tex]f(x)=x^2+2x+1[/tex]

To find:

The value of [tex]f(x+h)[/tex] in simplified form.

Solution:

We have,

[tex]f(x)=x^2+2x+1[/tex]

Putting [tex]x=x+h[/tex], we get

[tex]f(x+h)=(x+h)^2+2(x+h)+1[/tex]

[tex]f(x+h)=x^2+2xh+h^2+2x+2h+1[/tex]

[tex]f(x+h)=x^2+h^2+2xh+2x+2h+1[/tex]

Therefore, the simplified value of [tex]f(x+h)[/tex] is [tex]x^2+h^2+2xh+2x+2h+1[/tex].
