Let f(x) = 2x + 5 and g(x) = x^2 - 3x + 2
denis-greek [22]

Answer:

The answer to your question is below

Step-by-step explanation:

f(x) = 2x + 5

To solve letter a, just multiply each term of f(x) by 3 and subtract 2.

a) 3f(x) - 2 = 3(2x + 5) - 2

                 = 6x + 15 - 2

               = 6x + 13

To f(x) subtract twice g(x)

b) f(x) - 2g(x) = 2x + 5 - 2(x² - 3x + 2)

                    = 2x + 5 - 2x² + 6x - 4

                    = -2x² + 8x + 1

Multiply 5 by each term of f(x) and divide it by g(x)

c)      \frac{5f(x)}{g(x)} = \frac{5(2x + 5)}{x^{2} - 3x + 2}  

                = \frac{10x + 25}{x^{2}-3x + 2}

Gary has (20x + 7) dollars. Gary decides to buy two pairs of jeans. Each pair of jeans costs (2x - 3) dollars. write an expression that represents how much money gary will have left over after the purchase then simplify your expression

Answer:

$(16x - 1)

Given that:

Amount Gary has = $(20x + 7)

Price per pair of jeans = $(2x - 3)

Number of pairs = 2

Cost of 2 Jean pairs = 2 * $(2x - 3) = $(4x - 6)

Amount left after purchase :

$(20x - 7) - $(4x - 6)

20x - 7 - 4x + 6

20x - 4x - 7 + 6

$(16x - 1)
