A computer repair shop charges a flat rate of $50 plus $35 per hour spent repairing each computer. Let H be the number of hours spent repairing a computer, use function notation to write an equation that gives the total charges for repairing a computer as a function of h. Graph the function.

f(h) = 50 + 35h

Step-by-step explanation:

Let h = number of hours spent repairing a computer

if a computer repair shop charges a flat rate of $50 plus $35 per hour spent repairing each computer, then:

f(h) = 50 + 35h

graphing the function:

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
