The cost of creating a software program is $5000. Every extra feature added to the software costs $100. The total charge of the software with x extra features is given by the function f(x) = 100x + 5000. How will the graph of this function change if the basic cost is raised to $5200 and the cost of each extra feature is increased to $120? answer choices
the graph will be translated 120 units down and rotated about (0, 5000)
the graph will be translated 120 units up and rotated about (0, 5200)
the graph will be translated 200 units up and rotated about (0, 5200)
the graph will be translated 200 units down and rotated about (0, 5000)

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
